The Cooler Master V850 V2 Gold is a powerful and efficient PSU. It can handle the power requirements of a high-end GPU such as the RX 7900 XTX. Its platform is designed to deliver high performance and save you money on electricity bills. While it may not be at the top of its class, it is still a solid choice that is worthy of consideration.
Its major competitors in the 850W category include the Seasonic Focus Plus Gold 850, Corsair RM850x and RM850, XPG Core Reactor 850, and the Super Flower Leadex III and V models. With the recent release of demanding high-end graphics cards from Nvidia and AMD, the 850W category has become increasingly popular. Since these cards require a strong power supply to function properly.
This PSU offers ample connectivity options with two EPS and six PCIe connectors. It’s noteworthy that it comes with three PCIe cables, which can be utilized in high-end VGAs with three PCIe sockets. It is worth noting that it is recommended to not use both PCIe connectors of the same cable with high-wattage graphics cards such as Nvidia’s. But, the 7900 XTX should not pose a problem. The number of peripheral connectors is sufficient, however, it could be improved by having more space between them. On the downside, it does not have in-cable capacitors.
Considerations for the best PSU for RX 7900 XTX
The first thing to bear in mind is the recommended PSU capacity for the 7900 XTX. According to AMD, a 750W PSU will suffice to feed the GPU and the rig. However, we consider that amount a bit on the edge. It won’t leave you any space for overclocking or even upgrading other components of your PC to be more power-hungry. So the first thing to consider will be that the PSU has a wattage of at least 850W.
The second thing to consider is the efficiency rating of the PSU. A high-efficiency PSU will use less power to run, which can save you money on your electric bill and help keep your PC running cooler. Look for a PSU with an 80 Plus rating of at least Bronze, which means it’s at least 82% efficient.
Another important factor to consider is the number of connectors and the type of connectors available on the PSU. The 7900 XTX requires one 8-pin and one 6-pin power connector.So make sure the PSU you choose has those connectors available. Additionally, it’s a good idea to choose a PSU with plenty of additional connectors for other components in your PC, such as extra hard drives or fans.
It is also important to consider picking the best all-round elements for your rig. What do we mean by this? Well, you are going to want to pick the top GPU and CPU to maximise your gameplay and overall experience. We have curated guides for all of these features so make sure to check them out below.
