That said, there aren’t specific benchmarks like you’d find with a CPU, which would tell how a PSU performs, which can make selecting one a bit challenging. On top of that, there is a sea of options available from various brands, which is great, but too many options can get confusing. 

So, if you find yourself in the same boat, we’ve got you covered. We took the liberty of doing the research for you and put together this in-depth guide that lists multiple options, their details, and the pros and cons so you can make an informed decision. So, without further ado, let’s get right into it.

How we picked

It comes as no surprise that PSUs don’t get the limelight that CPUs or GPUs get because they lack the bells and whistles or simply the “wow” factor. That said, a PSU is the most important component in any build as it is responsible for ensuring that every component gets the necessary power and saves them in case of a surge. 

So, considering its purpose, we take into account the efficiency, fan size, capacitors, form factor, and modularity of each PSU, test them in-house, and present you with a list of contenders that were able to tough it out. If you’re interested in learning how we test our CPUs, GPUs, routers, and printers, check out our PC Guide Testing Lab, where we explain the process in detail. Besides that, we’ve also explained how we test and review products to provide the utmost clarity to our readers.

Corsair is known for producing many components, and its power supplies are well-liked among users. For our top pick, we went with the Corsair RM750x. 

This is an ATX power supply unit with dimensions of 150mm W x 86mm H x 160mm L (5.9” x 3.3” x 6.2”). What this means is that it doesn’t have the form factor you’d find in an SFX PSU, but it should comfortably sit in mid- and full-tower cases. An advantage of ATX power supplies is better heat management due to their size. Since the internal components aren’t cramped, the thermal output has more space to dissipate. 

The RM750x is also fully modular, meaning the cables aren’t attached to it. This should allow you to only connect the cables you want and put the rest of them back in the box, leading to less clutter and better cable management. As to what cables come with the RM750x, you should get the following:

These cables should be more than enough for even the most high-end setups and should ensure that you can power everything adequately in your build. 

This PSU has an 80-plus efficiency rating of Gold, which means that it should be at least 87% efficient at 50% load. Considering the efficiency of any PSU at 50% load is a sweet spot as it isn’t under a lot of load or sitting completely idle. However, according to Cybernetic, the RM750x is 88.397% efficient at 115V and 90.485% efficient at 230V. 

These percentages are great as they showcase minimum electricity loss and maximum utilization of the PSUs draw from the socket. This also means lower electricity bills in the long run.  

Regarding its noise output, according to Corsair's quick start guide for RM750x, it should generate less than 5dB at 300W; for reference, a whisper, generally, is around 30dB. The higher you go, the more sound it’ll make, but at its maximum operational capacity, 750W, the noise level should be around 35-36dB. 

It also features a 135mm magnetic levitation or maglev fan. Due to the magnetic separation, these fans don’t have any moving parts coming in contact. In other PSUs, bearings and fluid keep the fan spinning, but as time goes on, the fluid can dry up, leading to increased friction, noise, temperature, and the eventual failure of the fan or even the PSU. However, since maglev fans don’t have any moving parts coming in contact, they have a longer lifespan and almost no noise. 

This RM750x also has a Mean Time between Failure (MTBF) of 100,000 hours. To put things into perspective, that means the PSU or any internal component can fail in 11 years. While this isn’t a definitive value, and the output can change depending on various external factors such as temperature, surge, or physical damage, it is good to know that a reliable PSU is powering your rig. 

Also, it has a 10-year warranty, so if it fails, you can get it repaired or replaced during that time. What more could you ask for? 

Lastly, it comes with Overvoltage Protection (OVP), Undervoltage Protection (UVP), Short Circuit Protection (SCP), Overtemperature Protection (OTP), and Overpower Protection (OPP). These protection technologies help ensure the PSU's longevity and prevent PC components from frying.

To help you understand these technologies, we’ve explained them below. 

Overall, the RM750x is a solid power supply unit with excellent protection features, an aesthetic design, a low noise output, and, best of all, its fully modular nature. 

What users say

According to Amazon reviews, this power supply unit has a stable output, great efficiency, low acoustics, and the ability to power various setups. One reviewer stated: “I fully recommend this product if you want enough power to provide for any gaming build with a good amount of headroom for future hardware that may consume more power.”

Next, we have the perfect PSU for all the minimalist design enthusiasts or those with a smaller PC case, the Corsair SF850L. We had the pleasure of testing this PSU in-house, and in our review, we found that it has great performance and efficiency, but the small form factor contributes to some extra noise. 

This PSU has dimensions of 130mm L x 125mm W x 63.5mm H (5.11” x  4.9” x 2.5”), making it much smaller than ATX power supplies and enabling it to comfortably fit inside small PC cases. While SFX PSUs do have the advantage in smaller spaces, their internal components pay the price for it as they have less space between them.

This can lead to overheating issues if not adequately cooled down. That said, this power supply unit has a 120mm Fluid Dynamic Bearing (FDB) fan, which should help keep its temperature at manageable levels. These fans are quiet and can be mounted in various orientations without compromising the fan spin.

That said, during our testing, it produced 36.09dB at 115V and 35.92dB at 230V. This aligns with its Cybernetics rating of Standard+, which is for the 35dB to 40dB noise range. While it isn’t very loud, generally, 40dB is compared to the sound level of a library or bird calls; it is comparatively more audible than other PSUs on our list. 

As a small form factor choice, it provides great power and performance with great efficiency. 

Regarding its efficiency, it has two ratings: 80 Plus Gold and Cybernetics gave it a platinum rating. However, its average efficiency in our tests was 90.577% at 115V and 92.33% at 230V. This means it certainly matches Cybernetics' platinum standard, so it's like getting a platinum PSU for the price of a gold PSU. 

This PSU is also fully modular, meaning you can pick and choose which cables to use and reduce the clutter of additional wires. With this PSU, you should get:

A neat aspect of this power supply is that despite its small form factor, it still has the capability to output 850W of power on the single +12V rail and 150W on the multi, +3.3V, and +5V, rails. This means that you should be able to get more than enough juice to power your rig and comfortably overclock your GPU and the CPU without worrying about low power issues or crashing. 

Along with its small size, it is also fully modular, which is great for cable management but also allows you to add various components when the need arises. On top of that, it has the same 100,000 MTBF hours as our top pick. However, it only has a seven-year warranty, which is less than RM750x’s ten years, but it should still be enough to shield your PSU through various upgrades and any potential failure or damage.

Last, it comes with a handful of protection technologies, the same as the RX750x. However, it also has Catastrophic Failure Protection (CFP), which ensures that the PSU shuts down in case of failure due to flame, fused PCB conductor, charred PCB, smoke, etc. 

So, all things considered, the SF850L is another solid addition from Corsair, and given its performance and price tag, it is worth the investment if you’re on the market for an SFX PSU. 

What users say

The user reception of the Corsair SF850L is massively positive, and its reviews praise it for its compact design, efficiency, and stable performance. Many reviewers were pleased with its quiet operation, which should let you know that 35-36db isn’t deafening. One reviewer stated: “With its efficiency, reliability, modular design, and quiet operation, it provides everything you need for a high-performance system without compromising on space.” which we believe sums up this PSU perfectly.

For our third pick, the reign of Corsair continues with the HX1000i power supply as our best efficient pick. This PSU has a platinum efficiency rating from Cybernetic and 80 Plus. In our Corsair HX1000i review, we verified its operational efficiency with our test setup and were glad with its performance. 

This is a fully modular ATX power supply unit with dimensions of 180mm L x 150mm W x 86mm H (7.09” x 5.91” x 3.39”). These dimensions mean it needs a spacious casing to be comfortably housed, and it isn’t designed for mid-tower or mini PC cases. 

That said, its full modularity means the cables won't be an issue even if you’re slightly tight on space but can manage to fit it. You can only connect the necessary cables, keep the rest stored away, and bring them out when you need to connect another component. As for what cables come in the package, you should get the following: 

These cables should be enough to connect and power various components, with enough left over for future upgrades. 

It has a 140mm FDB fan, which makes sense since it's a powerful PSU and requires adequate airflow to keep it cool. Cybernetics has rated this PSU as an “A” in noise levels, which means its range is 20-25dB. This noise level is barely noticeable, yet the fan does a good job of keeping the temperature under control. 

The Corsair HX1000i is an outstanding power supply, for a component that might not be at the forefront of your build it brings about so much more than the rest.

Regarding its performance and efficiency, our testing found that it remained at 90% efficiency when idle and peaked at 93.93% when tested against heavy workloads. So, not only does it provide a good overhead for extreme hardware and overclocking for your system, but it also keeps it running optimally and ensures low electricity bills in the long run.

Our findings matched the Cybernetic results, which claim that the HX1000i has an 89.9% average efficiency with 115V and 91.4% efficiency with 230V.

This PSU comes with 2 EPS and 5 PCIe connectors, meaning you should have enough cables to power various PCIe devices. The 12VHPWR connector, in addition to its ATX 3.0 support, should ensure you can effortlessly run modern Nvidia and AMD GPUs. 

The maximum load of its 12+ single-rail connection is 83.3A, which means you should have plenty of headroom to power an overclocked GPU. If the power draw exceeds that, the OCP should trigger a shutdown, saving your components from shorting. 

The HX1000i has a zero RPM mode, which means the fan won’t spin unless necessary. This should reduce the already low noise levels but ensure that the PSU won’t heat up, as the fan will start spinning as soon as load is detected. 

Lastly, the most cool aspect of this PSU is its compatibility with Corsair’s iCUE software. This should enable you to set the fan curve according to the workload and temperature, check the power settings, and more. This is a great addition, particularly for individuals located in hotter regions, as the components require more cooling due to ambient temperature. Setting custom fan curves should help with that. 

Overall, this is one of the best PSUs available, and while it does come at a premium, its performance and efficiency make it worth every penny.  

What users say

According to customer reviews on Amazon, this PSU has amazing performance, efficiency, and build quality. The almost noiseless acoustics of this power supply are a major hit among the reviewers, and one user stated: “I would wholeheartedly endorse this PSU and wouldn't hesitate to purchase it again.” 

For our more budget-conscious readers, we recommend giving the Thermaltake Smart RGB 500W power supply a shot. In our Smart RGB 500W review, it had decent performance fitting for a budget option. 

This is a non-modular PSU, which means its cables are permanently attached to it. In terms of cable management, this means you won’t have the refinement of a fully modular PSU, and you’ll have to tie the unused cables and store them in the PSU compartment. As for the cables, it has the following:

This is 150mm in length, 140mm in width, and 83mm in height (5.9” L x 5.5” W X 3.3” H). These dimensions are seen in most ATX PSUs, which means the Smart RGB 500W can fit in a mid-tower case, but that wouldn’t be possible in a smaller casing. 

It features a 120mm fan with a maximum RPM of 1800. According to Thermaltake, it has intelligent RPM control, meaning it’ll adjust its speed according to the load and temperature. They also claim that it has a noise level of 27.1dB at 100% load. Our testing found that it reached 43.97dB and 43.32dB for the 115V and 230V versions, respectively. According to the Cybernetic noise level standards, this puts this PSU in the standard category. 

The Thermaltake Smart RGB 500W is a perfectly fine choice for a budget build when you want a good value option.

Regarding its efficiency, Thermaltake has rated it 82-86% efficiency at 20%-100% load. We tested its efficiency for the 115V and 230V versions, and it managed 82.838% and 85.490% efficiency, respectively, which makes sense since it has an 80-plus white rating. 

So, it delivers what it promises in terms of efficiency, but the acoustics are far from quiet, and if you want a noiseless build, this PSU wouldn’t be an ideal fit. 

The Smart RGB 500W PSU comes with an RGB lighting button on the back, which you can turn on/off for RGB effects. There are a multitude of effects available, and you should be able to choose the color that matches the aesthetic of your build. 

Regarding protection technologies, it features OVP, OPP, and SCP. These technologies should protect it from undervoltage or a power surge by turning it off immediately when the current exceeds the value set as the limit. The Overvoltage protection is set at the following values:

In addition, it has similar 100,000 MTBF hours but a 5-year warranty. That said, we need to keep in mind that this is a budget pick, and options with better features and warranties also come with a directly proportional price tag.

Overall, this is a solid budget PSU choice. While its fan noise might deter some from opting for it, this should work perfectly fine if you’re operating on limited cash and your setup doesn’t require a heavy PSU. 

What users say

According to Amazon reviews, the Thermaltake Smart RGB 500W PSU is a reliable and inexpensive option that delivers what it says. One reviewer said: “No experience with a warranty claim as I've never had to do that with these,” which tells that they are more than satisfied with their purchase and never experienced any faults.

For our last pick, we see Corsair making a coming back and planning to conclude things with a bang. And for that, we’ve got the RM850x Shift White PSU. 

This is an ATX power supply unit with dimensions of 160mm L x 150mm W x 86mm H (6.2” x 5.9” x 3.3”). This means it's not as small as an SFX PSU but smaller than the HX1000i. So, it should fit snuggly inside a mid- or a full-tower case. 

That said, the Shift series from Corsair brought an interesting design change by moving the cable interface on the side of the PSU. This should allow for easier cable management, combined with its fully modular nature, and enable different installation settings. 

The RM850x Shift White is fully modular, which allows you to add or remove the connecting cables depending on the requirements. For example, if you want to expand your storage by installing an HDD, you can do so by connecting the HDD to the power supply and attaching a SATA cable to the HDD. As for what cables come with the RM850x Shift White, you should get the following:

In addition to the necessary cables, like the ATX power cable, the 4 PCIe cables should allow you to connect multiple PCIe devices, allowing you to customize and upgrade your build further. 

This PSU has an 80-plus efficiency rating of Gold. This generally means that a PSU is 87% efficient at 20% and 100% load and 90% efficient at 50% load. This gives us an idea of how a particular PSU should perform under heavy loads and idle conditions. 

The higher the efficiency, the more electricity is utilized instead of wasted as heat, resulting in lower electricity bills. That said, according to Cybernetic, the RM850x Shift White is 88.672% efficient at 115V and 90.817% efficient at 230V, which puts it in the Cybernetic Gold standard as well. 

Cybernetic gave it an “A” for fan noise, meaning its noise output falls between 20 and 25 dB. According to the RMx SHIFT quick start guide, it should have an output of 20db at 680W and gradually move above the 30dB mark as the load reaches its maximum capacity of 850W. That said, even if you manage to draw out its full potential, 30db shouldn’t be bothersome as it is generally compared to the sound level of a whisper. 

It also features a 140mm fluid dynamic bearing or an FDB fan. These fans are better than rifle-bearing fans and can be mounted in different orientations without compromising the fan spin. Since it is a powerful PSU, the 140mm fan should keep it cool, and, as we discussed, it doesn’t make much sound either. On top of that, it has a zero RPM mode where the fan stops spinning if it doesn’t detect a significant workload. This should also contribute toward the unit consuming less electricity but ensure good cooling as it should start working as soon as the workload is detected. 

This RM850x also has a Mean Time between Failure (MTBF) of 100,000 hours. This means the unit or the internal components can fail once in 11 years. That said, it comes with a 10-year warranty, which is plenty of time. So, if it fails in that time frame, you can claim the warranty to replace or repair it. However, we recommend reading the fine print of the warranty claim as there are some factors that nullify a warranty claim, like water damage in the case of mobile phones and such. 

This power supply unit also has a handful of protection technologies that safeguard its operations. These technologies include the following: 

All of these safety measures ensure the PSU runs optimally, and any low voltage or power surge will shut it off before it damages itself or short-circuits your PC components.

Lastly, it comes with Overvoltage Protection (OVP), Undervoltage Protection (UVP), Short Circuit Protection (SCP), Overtemperature Protection (OTP), and Overpower Protection (OPP). These protection technologies help ensure the PSU's longevity and prevent PC components from frying.

What users say

According to customer reviews on Amazon, this power supply unit is outstandingly efficient and reliable. Its modular and new design allows for easy cable management. Its low-noise fan is well-liked, and even at high loads, it's barely noticeable. One user stated, “I highly recommend the Corsair RM850x to anyone in need of a powerful, efficient, and silent power supply for their PC build. Corsair has once again raised the bar with this outstanding product.”

How to pick the best power supply 

Before you settle on any one power supply, there are a couple of factors that you need to consider. Keeping those in mind should help you narrow down your list of options and select a PSU that has a good performance-to-value ratio and is the perfect fit for you. We’ve listed some of the factors below. 

Power requirements

The first factor you need to consider is your power requirements. For example, if your setup has plenty of fans, RGB components, and an RTX 4090 paired with an i9-13900K, a 500W would be too underpowered, and either your system won’t boot, or it’ll keep crashing. In that case, opting for a 1000W or even a 1200W PSU would be better suited.

On the other hand, if you have a budget rig with more power-efficient components like the Ryzen 5 5600X paired with an RTX 3070 Ti, then a 750W or even 650W PSU should be able to power all of it without disruptions.

So, calculate how much power each component requires and opt for a PSU with a 100W overhead to the total number. For example, if your complete system requires 550W, a 650W PSU would be ideal.  

Form factor 

The next thing you need to consider is how much space your PC case has to accommodate a PSU. Depending on that, you’ll have to get an ATX or an SFX PSU. SFX PSUs are smaller in size and can easily fit into smaller cases. However, if space isn’t an issue, an ATX PSU should serve you well, and they have better thermal design. 

Efficiency

The PSU's efficiency rating determines how much energy is utilized and how much is wasted. For example, there are six standards: 

The higher you go, the more efficient a PSU is, and the less electricity is wasted. This results in lower electricity bills and peace of mind that your system is well protected, which is priceless. 

Modularity 

There are three types of PSUs: modular, semi-modular, and non-modular. The modular PSU is fully customizable in the sense that you can only attach the cable you need and put aside the others. This leads to better cable management and less clutter.

Semi-modular PSUs only have a couple of cables attached, while the rest can be attached if needed. The attached cables generally include the ATX 24-pin, the 8-pin CPU connector, and others. 

Non-modular cables have all the cables permanently attached, meaning that you can’t remove any of them. With these PSUs, the cables that won’t get used are stuffed inside the PSU compartment, which leads to poor cable management and possibly overheating issues since everything is cramped up.  

Is a 1000-watt PSU overkill?

There isn’t a one-size-fits-all answer to this question, and it varies from scenario to scenario. For example, if you’re running an RX 590 with an i7-4770 processor, a 1000-watt PSU is overkill, as a 500 or even 450W PSU could power that setup.However, if you’re running an RTX 4090 with an overclocked i9-13900K, a 1000W power supply should be a good fit, and some might even suggest going for the 1200W category. So, it all depends on your components and whether you’re overclocking them. 

Producing CPUs with a TDP that consumes a low wattage has become a standard for AMD; the Ryzen 7 5700X3D has an efficient TDP that only consumes 105W. With this in mind, we’ve decided to compile a list of the best PSUs for the Ryzen 7 7500X3D. We will consider this CPU as a gaming unit that will normally be matched with a mid-range and above GPU. So, PSU wattage will vary in accordance with which GPU it’s paired with.

As a rule of thumb, we’ll include PSU above 650W up until 1000W to consider every type of user. Whether you’re a budget user who will pair it with an RTX 3060 or 4060 Ti or a power user who will push the CPU to its limits, pairing it with an RX 7800 XT or an RTX 4070 Ti Super.

Considerations for the best PSU for 7600 XT

Choosing a power supply (PSU) for your PC might seem daunting, but understanding key aspects simplifies the process. Here's a breakdown of crucial factors to consider when pairing a PSU with your RX 7600 XT.

Wattage

Wattage denotes the PSU's maximum power delivery. As mentioned, AMD recommends a minimum 600W PSU for the RX 7600 XT. However, consider future upgrades. High-end graphics cards like the RTX 40-series or RX 7900 XTX demand significantly more power, necessitating a higher wattage PSU (ideally 850W or above) for optimal performance.

Efficiency

The 80 Plus certification denotes a PSU's efficiency - its ability to convert AC power to DC power for your components. While a Bronze-rated PSU might suffice for budget builds, aiming for Gold-rated or higher is recommended for the RX 7600 XT. This translates to lower operating temperatures within your case due to reduced heat generation from the PSU itself, along with lower energy consumption for cost savings in the long run. If you want to go more premium, you can check out some of the best high-end PSUs.

Design

Modular PSUs offer a significant advantage in cable management. Non-modular PSUs have fixed cables that can block airflow, and they also make building and maintaining your system a bit harder. Semi-modular units have detachable peripheral cables, allowing you to connect only the essential ones for your build.

Fully-modular PSUs are the pinnacle of cable management. All cables are detachable, enabling a clean and organized interior. This not only improves aesthetics but also enhances airflow within the case, potentially contributing to lower component temperatures. While fully modular PSUs typically carry a premium price tag, the benefits for airflow and ease of maintenance are substantial, especially for performance-oriented builds.

Cooling

When selecting a PSU, consider its cooling solution. Higher wattage PSUs often utilize larger fans to dissipate heat effectively. Look for PSUs with temperature-controlled fan profiles that adjust fan speed based on the PSU's load, ensuring quiet operation at idle and optimal cooling under heavy loads.

By prioritizing these factors, you can select a PSU that delivers the power, efficiency, and clean aesthetics necessary to fuel your RX 7600 XT and future upgrades.

What is the 7600 XT minimum PSU requirement?

As per AMD's recommendation, the minimum PSU requirement for the Radeon RX 7600 XT is 600W. With that said, you an consider going a bit above 600W if you're planning to make upgrades.

Power supplies are often overlooked when considering how your computer system is built effectively. However, if your PC uses a powerful GPU, such as Nvidia’s RTX 4070 Ti Super, then choosing the right power supply can be an important step in ensuring your system runs smoothly. In this article, we've cherry-picked a list of the best PSUs for RTX 4070 Ti Super.

Products at a glance

How we picked

On the whole, we've taken a specific focus on PSUs that provide stable and efficient power delivery, particularly under typical gaming and workload scenarios. This involves evaluating PSUs for their ability to maintain consistent voltages and handle peak loads without faltering. The goal is to recommend units that not only meet the power requirements of the RTX 4070 Ti Super but also offer reliability and longevity: leaving room for upgradeability is a smart move. Of course, as we mentioned earlier we've already done our review of the 4070 Ti Super, so we're familiar of how it performs under load, and are comfortable recommending this list of CPUs we think will be a good match-up based on our hands-on experience.

Recommended specs don't go out the window either. We've noted how the 4070 Ti Super uses the same 285 watts of power as the RTX 4070 Ti, and connects to your power supply with the same (problematic) 16-pin 12VHPWR cable. Nvidia advises a 700 total system watts as a minimum for both cards. Needless to say, all our picks today go above and beyond this.

Noise level is another consideration, especially for users who prefer a quiet working or gaming environment. By integrating technical performance with user experience, our recommendations aim to provide users with PSUs that not only meet the power needs of the RTX 4070 Ti Super but also fit seamlessly into their overall system build.

What are the 4070 Ti Super PSU requirements?

As we mentioned just above there, Nvidia recommends a 700W minimum PSU for both the RTX 4070 Ti Super and the original 4070 Ti, so going for a unit of 700W or 750W at least should get you covered on the power supply front. In terms of dipping above or below this figure, it could be said that if you have a CPU that uses under 100W under full load, you might be fine with a 600W unit - these recommendations might be assuming that you've got something like a 14900K in your rig that's already pulling 300W. However, we advise that you aim for above minimum requirements, as when you eventually upgrade to a bigger and better card, you'll already have the necessary power already available to you.

Features and considerations - GTX 1080 Ti PSU requirements

When it comes to finding a suitable power supply, you can’t just go for any. It’s important that the power supply has the right amount of wattage needed for the graphics card so that you aren’t wasting electricity, and so that you aren’t possibly damaging the components by not having a high enough wattage. For the GTX 1080 ti, it is recommended that you use a power supply with a minimum of 600 watts, so anything above that should be fine. However, going too high above that will just lead to waste, so the ideal is around 600 to 800 watts, or so.

There are plenty of suitable power supplies available, so choosing the best possible one might be tricky, especially considering that they all very much look the same! So let’s look at the main factors that you can take into consideration. Remember that the power supply needs to suit your needs and preferences, and not the other way around!

Efficiency

When it comes to a power supply, efficiency is key. The higher the efficiency, the better the performance and the smoother and more stable the supply of power will be. Usually, this efficiency will be rated and ranked accordingly, so that you can quickly see how good it is.

For the GTX 1080 ti, you should aim for a power supply that has a rating of 80+ Gold, 80+ Platinum, or 80+ Titanium. Any lower ranking will likely be unable to keep up with the graphics card, and will therefore not be functioning at the best possible capacity.

Fan Cooling System

One of the biggest issues in gaming setups is overheating. With so many components, working at a demanding pace, and at such a high capacity, it is no wonder that the power supplies in use are going at full speed, with the risk of overheating and malfunctioning. That is why the fan cooling system is one of the most important factors to consider, as it is what will keep the power supply running smoothly and without interruption, and what will protect it from becoming damaged and worn too soon.

Whether it uses intelligent thermal technology or has an auto-adjustable fan speed, it’s important that the fan system is able to detect and accurately prevent overheating.

Design

Although most power supplies pretty much look the same, it’s still important to pay attention to the design, and the different features that it presents. A more compact design is usually better, not only because it will be better to fit into your setup, but also because it will be a lot less prone to overheating. There are also some designs that purposefully situate extra components at the top of the power supply, leaving the bottom less clustered, for an improved airflow that once again helps prevent overheating.

Something we recommend is that you look out for modular or semi-modular designs. With these, you have the ability to only use the cables that are needed, allowing you to store away all other cables, as they can be removed from the power supply. This helps reduce clutter, improves the airflow, and it also saves you space, and makes the setup look a lot better!

When is it time to replace my GTX 1080 Ti PSU?

On average, a power supply for an at-home gaming setup should last you between five to eight years. However, the amount of time a power supply lasts depends on the use that you give it, and on the care you give it.

Ultimately, you should replace the power supply whenever it starts to become faulty, or if it begins to malfunction on a regular basis. You should also replace it if you switch from the GTX 1080 Ti to a different graphics card, as it will then require a different amount of power.

In this article, we will guide you through the process of selecting the best PSU for your RTX 4070 build, taking into account the efficiency, reliability, and overall value. With the right power supply, you'll be able to harness the full potential of your RTX 4070 and enjoy an incredible gaming experience.

Considerations for the best RTX 4070

When selecting one of the best PSUs for your RTX 4070, there are several factors to consider. Each of these aspects plays a crucial role in ensuring you have a stable and efficient system that can handle the demands of the GPU and other components in your build.

First and foremost, consider the wattage of the PSU. Although the recommended wattage for the RTX 4070 is 600W, it's a good idea to leave some headroom for future upgrades, overclocking, or other power-hungry components. A PSU with slightly higher wattage can provide extra peace of mind and ensure your system remains stable even under heavy loads.

Efficiency is another important factor to consider. PSUs with higher efficiency ratings not only save you money on electricity but also generate less heat, which can help keep your overall system temperatures in check. Look for PSUs with an 80 PLUS certification, which guarantees a minimum efficiency of 80% under various loads. The higher the certification level (Bronze, Silver, Gold, Platinum, or Titanium), the more efficient the PSU.

Next, consider the form factor and dimensions of the PSU, as this will determine whether it fits in your PC case. The most common form factor is ATX, but there are smaller options like SFX or SFX-L for compact builds. Make sure you choose a PSU that will fit comfortably in your case and leave enough room for proper cable management.

Cable management is another crucial aspect to consider when selecting a PSU. Modular PSUs allow you to only connect the cables you need, reducing clutter and improving airflow within your case. Semi-modular and non-modular PSUs are typically more budget-friendly but can be more challenging to manage due to the fixed cables.

To put it simply, the sudden loss of power to a PC or home working system can be pretty catastrophic, especially if you're working on a creative project, complex equations, or even upholding a business. Luckily, in order to prevent that, some great innovator came up with the uninterruptible power supply - a handy little tool that acts as a backup generator when you're experiencing a power cut or a power shortage. It's basically a backup battery for when you're not getting electricity from your mains.

There are many uninterruptible power supply options to choose from on the market, and if you're a first time buyer, it can be hard to know what to look for. In this article, we’ve boiled down the best of these options to five strong top selections. Whether you’re using a low-power laptop, a console, a high-end gaming PC, or anything in-between, one of our recommendations should suit your budget and your needs. We’ll walk you through each of the main specs listed, and help you make the right selection for you.

How we picked the best UPS

At PCGuide we know power – yes we keep things switched off when not in use –  and we know how underserved so many technology users are. So we’ve picked the best options for a range of use cases, drawing on our in-depth topic knowledge of both power supplies and PCs in general to separate the chalk from the cheese and outline a selection of top picks from across the board.

You may want to keep your laptop, tablet, or phone charged in an emergency or power-cut, or to keep playing on your console or PC ins a similar situation. As different devices have different power supplies, we’ve opted for a mix of the best UPS options to reflect this. How? By using our own knowledge and personal experience of units, as well as looking at prices and features and their requirement for specific users. So what follows is a considered and varied list of best UPS devices, which should sort you out in a pinch.

Our top picks

If you refuse to settle for anything less than the best, the APC Back-UPS PRO 1500VA is the right uninterruptible power supply for you. Its 1500VA/900W capacity should be more than enough for any modern gaming PC, as well as any monitors, TVs, speakers, or any peripherals you have plugged into it.

In addition to the crazy-high capacity of 900W, you also have stellar build quality and software. As the “Pro” in its name implies, this is a UPS intended for professional use, and it shows in its features and quality. All of the most important features are here: USB interface, great quality, great capacity, and a built-in LCD display to monitor your UPS.

If you refuse to settle for anything less than the best, the APC Back-UPS PRO 1500VA is the right uninterruptible power supply for you.

We really only have one downside of note for this unit: its high price. This is the most expensive unit on this list and is the highest-end UPS available to consumers. If you have truly high-end hardware, though, this is worth every penny. What’s an extra ~$170 to protect $1,000+ in hardware?

What users say

As our top pick, it's no surprise that the APC Back-UPS PRO 1500VA is highly rated on Amazon too, with 78% of users giving it that golden 5 star rating. In particular, users like the value that this UPS offers, as well as its security features and how easy it is to install. One user mentions that they would consider this unit an excellent "all-in-one solution that's worth every penny" that protects your electronics from under or overvoltage conditions. As we discussed earlier though, some buyers have mentioned that it has a tendency to get a little noisy when it's charging.

Next up is the APC 650VA Back-UPS unit. The 650VA here translates to 390W, which makes it ideal for full console + TV setups, as well as low-power PC setups.

In terms of PCs, you aren’t likely to be able to use this with budget gaming PCs. Even when their real wattage requirements are lower than the 390W target of this unit, you still face the issue of power supplies with low efficiency. Unless you’ve calculated your max wattage to be 350W or lower and you’ve invested in a 400W PSU with 80+ Gold Certification or better, you probably shouldn’t use this with a budget gaming PC.

The 650VA here translates to 390W, which makes it ideal for full console + TV setups, as well as low-power PC setups.

Where this UPS will come in handy is as a unit for low-power PCs and consoles. Many prebuilt HTPCs and office PCs, for instance, will have much lower wattages than the 390W target required by this unit. The gaming console with the highest power consumption (the PS4 Pro, at 310 Watts) also leaves generous room for a medium-sized HDTV to share the battery backup on this unit.

What users say

As you can tell from its dimensions, the APC 650VA Back-UPS is a much more compact UPS compared to others: and this is one thing that users on Amazon liked about it in particular. One user states that the unit does what it's supposed to do "with grace, simplicity, and intelligent design and forethought" - how's that for a compliment? However, similarly to the unit above, there are quite a few comments that pick up on the noise levels, with one user mentioning that there is an intermittent beeping "which occurs when the device is not connected to a power source".

This has over twice the total power capacity as the previous entry on this list. With a modern gaming PC, the 815W wattage is far beyond anything the PC should actually consume… so long as your PSU has a respectable power efficiency and isn’t larger than 800W, of course. (For reference: a modern high-end PC with an i7-9700K and RTX 2080 Ti should consume no more than 375 Watts of power before overclocking.)

All the extra wattage here should be suitable for a fully-fledged gaming setup. That means a large TV, speakers, or multi-monitor setup should all be within this UPS system’s capabilities, so long as you aren’t pushing its maximum with your PC by itself. The built-in display will also serve as a great way to measure your power consumption in real-time, so you know for a fact whether or not you’re pushing this UPS too far for its own good.

In terms of battery life and software features, CyberPower offers quality up there with the best in the industry, including APC. Plus, you also have the added benefit of voltage regulation with this unit, which should come in handy in areas with particularly poor or inconsistent power.

The only real downside with a UPS like this one is its high price, but if you truly want to protect your tech investment it’s worth every penny.

What users say

As you can tell from the photos, this unit is pretty easy on the eye (as far as UPS's go), so it's no shock that users on Amazon praised the CyberPower CP1500PFCLCD for its appearance: while one user comments that it's a "nice, small, and compact" unit, another mentions that "a reliable, feature-rich, and well-designed product that provides essential protection for my electronics". However, that's not to say that its performance wasn't complimented either - "its blend of performance, features, and value is unmatched".

If you’re looking for a computer battery backup, then you’re in luck; we’ve finally reached a UPS good enough for desktop PC usage.

As you may or may not know, most actual PC power consumption is well under 400W, even with high-end components. Modern PCs especially have low power requirements– my own PC at max load shouldn’t ever exceed 310 Watts, for instance. With an 80+ Gold-certified PSU, that means I should be consuming a maximum of ~370W, with a fair 50W remaining for my monitor and peripherals. Not bad, right?

Well… that is a little bad, actually. At least, it is bad if I were to be running my system at max load when my power goes out, since I would be dangerously close to meeting my maximum threshold. My PC is actually pretty old, though– what about a newer gaming PC?

Looking at our gaming PC build, these parts combined should never consume more than 250W. With an 80+ Gold Efficiency PSU, that’s about 300W of maximum power consumption. This leaves roughly 120W of power free for peripherals and a monitor, which is a much safer range to be working within.

You’ll want to calculate the exact power draw of your desktop PC to be sure, but any modern midrange gaming build or prebuilt PC should fall well under the limitations of this PSU.

In addition to the high-enough-for-proper-desktops wattage, you also have the added benefit of better software, auto-restarting functionality, and even a nifty little LCD panel to work with.

Things to consider in the best UPS options

Why you need a UPS (Uninterruptible Power Supply)

As the name implies, an uninterruptible power supply is just that: uninterruptible. This means power surges, blackouts, brownouts, and any other power-related problems won’t result in your UPS going offline. The UPS will only turn off if its battery is emptied, it’s turned off manually, or it is physically destroyed by an outside force. Otherwise, these machines are built to be durable and to resist even the worst power conditions.

The purpose of an uninterruptible power supply is to protect whatever is plugged into it. For a PC user, this means your PC and your monitor. For a console gamer, this means your console and possibly your TV, though you can safely turn off modern consoles using only the power button, unlike with desktop PCs. This same logic can also be used for non-PC or non-console devices, like Smart TVs or media players.

In the case of electronics, especially “smart” electronics like a PC, console, or smart TV, clean and consistent power is integral. With power surges or outages, you risk damaging or destroying the entire system, especially in the case of a power outage. If you’re also using your PC for important work, a sudden power outage can result in all of that work being lost.

To protect your likely expensive investment, an uninterruptible power supply is integral. This applies especially to areas that suffer from frequent power outages, particularly rural areas, extreme climates, or places with bad power grids.

In order to buy the right UPS, however, you’ll need to make sure that some basic requirements are met. The most important of them is wattage, which we’ll explain just below.

Wattage is the most important factor to consider when buying a UPS. The UPSes we’ve listed all come with VA and wattage ratings. You don’t need to worry about VA– it’s a different measurement for the same thing, and we’ve included the wattage ratings for each of the UPSes we have listed above.

To get a better idea of what you need, we’ll list common wattage ranges below.

As a PC user, you’ll always want to opt for a UPS with a wattage matching your PSU, with at least 50W extra power for a standard monitor or small TV. Higher-efficiency power supplies will also come in handy here, since PCs rarely need to pull 100% power load from their PSUs.

If you’re building a PC, and this is part of your building process, take a look at our power supplies guide as well.

Warranty

Note: If your battery dies after your warranty period has passed, you won’t get a free replacement. You’ll need to buy it instead.

Your warranty is fairly important here– be sure to register your UPS properly!

Your warranty will cover both your battery and the uninterruptible power supply unit itself. If either fails within the specified warranty period, you’ll be entitled to a replacement from the manufacturer. A 3 year warranty is standard, and this warranty period corresponds to the battery life expectations for your standard UPS battery.

What is a UPS?

The acronym UPS stands for Uninterruptible Power Supply. Essentially, if the power goes out, your devices shouldn’t do. This allows you to shut down and save work or turn devices off safely.

As such, UPS devices are rated for power (the amount they can supply) and LCD models will advise how run time they have in them too.

How do I connect to my UPS?

An important factor to consider when buying an uninterruptible power supply is its software.

Every uninterruptible power supply we’ve listed provides the software you can use to monitor the UPS. If you’re a PC user, this software can also be used to automatically shut down your PC once the UPS power backup battery life is low, which is especially great if you aren’t around to turn off the PC yourself. Aside from this basic functionality, higher-end software will also provide superior monitoring and control features.

In terms of interface, a USB interface is standard. You’ll see a USB interface for every UPS on this list, with the exception of a model that also offers serial connectivity.

Features and considerations

When deciding on what SFX PSU is right for you it's important to consider a number of factors. One of the main things to look at is longevity. How long do you think this PSU will last? And, will it work well with my system settings for an extended period of time? Usually, PSUs will have a warranty that demonstrates how long manufacturers believe their product will remain a reliable source of power. It's a good idea to look at this warranty and decide whether you think this means the product will last you a long time.

Another way to decide this is by looking at the future-proofing technology that has been included in the product. For example, if a PSU includes PCIe 5.0 then it will be able to withstand modern technologies that have been made with this feature. On top of this, efficiency is an important feature to consider when purchasing your PSU. Looking at the ratings of PSUs is a great indicator of how efficient your PSU will be. Anything with an 80 Plus rating will provide you with a reliable and efficient source of power.

What is the difference between SFX and SFX-L PSUs?

Both SFX and SFX-L PSUs are designed to save space within your build, however, there is a slight difference between the two in terms of dimensions. SFX-L are 30mm longer than SFX PSUs, so if you're looking for the most amount of extra space in your system then opting fo a smaller SFX-L might be the right choice for you.

Whether you’re just joining the PC enthusiast community or you’re a seasoned veteran with multiple builds under your belt, you should know that the power supply is one of the most important aspects of your build. With household names like Corsair and EVGA working around the clock to provide you with power-efficient and reliable PSUs (power supply units), this highly competitive segment of the PC component market has given birth to modular units. 

We've tested all three types of PSUs and have enough knowledge to let you know the difference between the three and which one you should go for. So, without any further ado, let's dive in! 

Fully modular, semi-modular, and non-modular PSUs - what are the differences?

If you've never built a PC before, then it is important for you to learn about each PSU type so you can get an idea about which one to go for. To help you out, we're going to discuss the key differences between all three types so you can make an informed decision. Also, we'd recommend checking out what power supplies ratings mean so you know what rating to aim for when selecting a PSU.

Non-Modular PSUs

Non-modular power supplies have all of the cables already connected to the power supply. They typically have a less-premium feel than their modular counterparts, have color-coded cables that are not usually braided, and have an overall outdated aspect. Non-modular PSUs are mainly for those who are tight on a budget or don't really care about the aesthetics of their build.

Still, don’t let that discourage you. Low-end power supplies still function in the same way high-end PSUs do. If you’re buying from a reputable manufacturer and factor in your components’ total power draw before buying, then you should be safe. However, make sure to get at least 80+ bronze certification, as it is an investment in both power efficiency and reliability. 

Non-modular PSUs are also ideal for beginners. Since all the cables are permanently attached, there is no need for you to worry about connecting or managing additional cables when building your PC. However, do keep in mind that this will make cable management difficult, as you'll have to do something about the unused cables since they can not be removed.

In case you're planning to get a non-modular PSU, we recommend checking out the EVGA 550W N1 Series PSU.

Semi-Modular PSUs

Semi-modular power supplies only have basic cables attached to the unit, like the 24-pin motherboard connector, the 8-pin CPU cable, and the PCIe power connector that will go into your GPU. Whatever else you may need to power your future system can be connected, so you can customize the power supply based on your needs while having the barebone configuration already installed. For example, cables like SATA, extra PCIe, and other peripheral cables can be attached/removed whenever needed.

In terms of budget, they’re in the middle, with the non-modular on the low end of the spectrum and the fully-modular models at the high end of the spectrum. Value-wise, this might be your sweet spot. You’re getting the best of both worlds while not paying for the full price of a modular power supply. However, do keep in mind that as some cables are still permanently attached to the PSU, semi-modular PSUs can get in the way of improving the overall aesthetics of your build.

If you're interested in getting a semi-modular PSU for your build, then you should check out the Corsair CX750M. This is a semi-modular ATX 750-watt power supply and is a great option for cards like RTX 4070 Ti and RX 7900 XT.

Fully-Modular PSUs

Modular power supplies allow you to use only the cables you need, making for better cable management, improved airflow, and a much cleaner aesthetic. However, while the modularity aspect is welcomed in almost any build, it also adds a bigger price tag to the component. But if you're all about aesthetics, then choosing a fully-modular PSU is the way to go.

Unlike non-modular and semi-modular PSUs, fully-modular PSUs have no cables attached to them. This allows you to improve the cable management inside your build, as you won't have to worry about taking care of unused cables. You can simply use the ones you need and leave the rest of them inside their box.

Fully modular PSUs can help give your PC a cleaner and more streamlined look. Improved cable management also leads to better airflow inside your case. However, compared to the other two types, fully modular PSUs are more expensive, have braided cable sleeves, and are bigger in size.

If you're opting for a fully-modular PSU, then we'd recommend the MSI MPG A1000G. This is a PCIE 5 and ATX 3.0 PSU and is ideal for high-end cards such as the RTX 4090, RTX 4080, and RX 7900 XTX.

Which PSU should you go for?

You’re probably wondering “What type of power supply do I need?”, and that’s a pretty fair question. First off, no matter the type of power supply, you need to make sure that it’s power-efficient. You should get at least 80 PLUS certification on your power supply. This means that at 20%, 50%, and 100% loads, it will convert at least 80% of the AC it draws from the outlet to AC, so it will draw 125 watts to output 100 watts of DC. This is important for your power bills and for the safety of your builds and components, as efficiency translates into better temps. As Intel claims, the more efficient your PSU is, the less power it uses, which leads to less heat generation.

Secondly, make sure you calculate the total power draw of your components and pick a power supply with a buffer. So, if your components need around 500 watts, invest in a PSU that’s rated for 650 watts or more. This way, you won’t put your components under stress, you’ll avoid random shutdowns at high loads, and you’ll gain more efficiency, considering that power supplies become more inefficient at higher loads. 

With that in mind, here’s where modularity comes into play. Picking a non-modular power supply is OK if you’re not interested in optimal cable management and clean aesthetics. If your PC case has a PSU cage, then you can use the cage to mask the extra cables without any airflow or visual penalties. 

You should get semi-modular power supplies if you’re interested in getting a value option that also provides you with good cable management design, higher-quality cables, and a better, more premium feel. 

Fully-modular power supplies are very useful in a lot of different cases. First off, they’re most likely better built, with hybrid fans running silently while keeping your unit cooled and premium cables giving you a professional and visually appealing finish. In addition to the premium materials, you can use fully-modular supplies to customize your PC. If you’re building in a small form-factor case, then you can order custom-length cables to maximize the airflow, a crucial aspect to consider when working in small cases. Moreover, you can also order custom sleeves and even individually-sleeved cables to give your build more character. If you want to explore some fully modular options, we recommend checking out the best high-end PSUs.

Conclusion

You should always aim to get a power supply with a higher efficiency rating and with a sensible buffer rather than investing in a semi or fully-modular unit. That being said, the extra money that goes into a fully-modular power supply ensures that you’re getting better-quality materials, better cable management options, and easier troubleshooting in case something goes wrong. If you're tight on a budget, then you'll have to skip the extra features and get a non-modular PSU. But if you want better aesthetics and flexibility, then you should definitely opt for either a semi or fully-modular power supply.
