In terms of pricing, you’ll find a bit of a range depending on what other components come with the PC itself.

• Includes Core-i9 14900KS for top tier performance
• Offers huge 64GB 6000MHz DDR5 RAM

If you want the very best combination of components in an RTX 4090 gaming PC then you’ll want the best of all CPUs – step forward the ABS Eurus Aqua RTX 4090 system. 

This PC features the incredibly quick Core i9-14900KS, alongside an Nvidia GeForce RTX 4090 GPU 24 GB, 64GB DDR5 6000MHz RAM, and a 2TB SSD. That’s quite the collection of components, and only slightly lacking if you want ample storage. 2TB is more than enough for most users though – unless you’re a content creator or otherwise require large amounts of drive space.

Let’s face it though, an i9 14900KS CPU paired with the 4090 is the pinnacle of performance in gaming PCs as of the 14th gen era, and there’s nothing this PC won’t be able to handle in multi-tasking, gaming, streaming, or editing functions. This PC does have a more understated appearance which will be better for those who prefer performance over appearance, but there is RGB support throughout, and a tempered glass side panel to help show off the core of the system.

The most impressive thing here though is the price, as this Advance Battle Stations Eurus Aqua system comes in at a similar price we’ve seen for systems lacking the pairing of 4090 and 14900KS. This system may not have additional features like a mouse or keyboard – you’ll need your own – and it may lack for some in storage. But otherwise, it’s a top-tier option. 

What users say

Owners of the ABS Eurus Aqua RTX 4090 prebuilt on Amazon have commented on just how well the PC works straight out of the box, stating it “Worked great right out of the box”, and that it’s an “Amazingly built gaming PC, everything comes built and it fires up just as it should”. Value was also a popular feature, with multiple buyers sharing that they think “This is a very powerful machine considering the lower price”, and that they’re “still trying to find out why this thing is so cheap and arrived so quickly”.

However, one caveat that came up was the size of the 4090 itself – it’s a powerful card, and this is obvious from how big it is. So, users have recommended that you “buy a support for the graphics card due to the large size and the risk of the graphics card sagging and damaging the pricey part.”

You won’t really find a budget RTX 4090 gaming PC, but you can find slightly more affordable options on the market that pack a punch – like the MPG Velox by MSI.

This gaming PC is built with an i7-11700F CPU, Nvidia GeForce RTX 4090 GPU 24 GB, 32GB DDR4 RAM, 512 GB SSD, and 3 TB HDD. Now while that’s not as maxed out as some of the other prebuilds on this list, it will still deliver when it comes to performance. The i7 CPU coupled with 4090 graphics can breeze through practically everything, gaming, multitasking, streaming, and more. 

One area it is slightly lacking is the case itself, however does have LEDs and RGB fans that can be customized through the app. It also comes with a wired backlit gaming keyboard and mouse, which is great if you want to dive right in out of the box – but ultimately we’d recommend swapping out with something a little more tailored to your needs. 

Overall, as far as affordability goes when it comes to RTX 4090 gaming PCs, this MPG Velox does hold some appeal. However, if you’re after the very latest components to go alongside your powerful graphics card, such as DDR5 RAM, a larger SSD, or a 13th Gen Intel CPU, you may find what you’re looking for by increasing your budget.

If you’re looking for an RTX 4090 gaming PC that packs one of AMD Ryzen’s best CPUs, we think this Yeyian offering is well worth considering.

This gaming PC packs a powerful AMD Ryzen 9 7950 X3D processor, which is one of the very latest to hit the market and comparable with Intel 13th Gen – to find out more about that particular processor, check out our 7950 X3D review. Alongside this, you’re getting 32GB DDR5 RAM, a massive 2 TB SSD, and a 2TB HDD, for speedy performance and excellent storage capabilities. 

When it comes to cooling, this PC boasts a 360mm AIO premium liquid cooler, alongside 3-120 mm and 4-140mm ARGB fans which keep things running smoothly, but without too much noise.  that maximizes cooling performance, 3-120 mm and 4-140 mm ARGB fans with low-noise efficiency.

As for design, we really like it. The RGB components look great, and the front of the gaming PC is quite unique with its mesh-like covering.

Overall, for those who want to game at the highest settings, stream, edit, and more, this gaming PC seems to tick all the boxes.

What users say

Across user reviews for the Yeiyan Odachi on Amazon, a common positive comment was on how the combination of components achieved really high performance. Some were straight to the point, simply saying “This computer has the goods on delivering fast results”, and praising that it’s a “well built PC using quality parts backed by extremely responsive and helpful support and customer service”.

However, buyers have also commented on some possible issues with the cooling capabilities of this case. One user in particular comments that their “only suggestion is not to try and overclock this machine without getting a better case. The case doesn’t cool well enough for that”

If you’re after one of the most premium RTX 4090 gaming PCs out there, then you’ll want to check out this Corsair Vengeance i8100 series prebuilt.

Corsair is one of the best brands for all things PC, and this rig is an absolute beast. Alongside its powerful RTX 4090 GPU, it features the still praiseworthy Intel i9 13900KS CPU, cooled by Corsair’s impressive iCUE H150i Elite liquid CPU cooler. This combination will ensure that you can throw everything at this PC and it will be able to handle it with ease. From AAA gaming at max settings to demanding rendering tasks, and much more.

In terms of the other components it brings to the table, you’re getting a massive 4TB M.2 SSD and 64GB of DDR5 RAM to keep everything running fast and give you plenty of space for gaming.

When it comes to design, we’d argue that this is the best-looking prebuild on the list.  From its synchronized lighting that can either react dynamically or be set to your own signature profiles, to its stunning case that really puts all these top-end components on full display, it’s an amazing-looking machine and one that’ll look fantastic in your setup.

Overall, if you’re looking to go all-in and really splurge with your budget, this is definitely an RTX 4090 gaming PC to consider.

The Skytech Gaming Azure is one of the best RTX 4090 gaming PCs you can buy now and is a great option for those looking to play AAA titles at some of the highest settings.

It features a powerful Intel i9-13900K CPU alongside its NVIDIA GeForce RTX 4090 GPU which should be able to handle pretty much anything you can throw at – whether that be playing games like Cyberpunk 2077 or handling complex 3D rendering tasks. It also packs a substantial 2TB SSD and 64 GB of DDR5 RAM – meaning you get pretty much all the space you need, plus more than enough RAM to keep everything running fast and smoothly. 

In terms of cooling, this gaming PC has four RGB RING fans to enhance airflow, and of course, the RGB lighting can be synchronized too. On top if that, we like the fact it’s a mid-tower gaming PC so it’s not going to completely dominate your setup and take up loads of space. 

Overall, as far as RTX 4090 gaming PCs go, we think this one has a lot going for it. Sure, it’s pricey, but if considering the qualify of all the components, we think it’s actually solid value for money.

What users say

Just as we’ve mentioned in our reasons for buying the Skytech Gaming Azure, reviews on Amazon also commented on how good-looking this PC is, with one buyer saying “The design of the kytech Archangel Gaming PC is a showstopper. The sleek black case with clean lines and well-placed air vents not only looks impressive but also contributes to efficient cooling during extended gaming sessions”. RGB was also highly praised, with users stating that “The RGB lights are just perfect”, and that “The colorful lighting not only adds a vibrant touch to my gaming setup but also enhances the overall gaming atmosphere”.

Things to consider when buying an RTX 4090 gaming PC

If you’re on the hunt for an RTX 4090 gaming PC, you’ll want to factor in a few things before making your purchase, especially as these are some of the priciest gaming PCs on the market.

Is an RTX 4090 gaming PC overkill?

It may sound obvious, but RTX 4090 GPUs are actually pretty overkill for most people. We’d say the best candidate for an RTX 4090 gaming PC is someone who uses it for playing AAA games at the very highest settings possible, someone who works in 3D rendering, or someone who is a mid-pro level streamer or competitive gamer. If you meet the requirements, great! But if not, we’d recommend going for something less powerful that will ultimately save you money, and be more appropriate for your needs.

How much should you spend on an RTX 4090 prebuilt gaming PC?

You’re looking at anywhere between $2500 to around $4500 from what we’ve come across, however, you may find some options lower if they are pre-owned or higher if they pack the absolute latest components or have something unique about them. At the lower end, you’ll come across gaming PCs that have older-generation CPUs, not as much RAM, and smaller SSDs. At the higher end, you’ll find the latest CPUs, loads of DDR5 RAM, massive SSDs, and also more visually impacting cases and lighting.

Is it worth getting an RTX 4090 gaming PC now?

Now is as good a time as any in our opinion. RTX 4090 gaming PCs are still the very best and we’re not expecting the 50-series options in the future to make them obsolete by any measure.
