To get the most out of the AMD Radeon RX 6900 XT GPU, you'll need a capable power supply (PSU). Luckily, AMD doesn't have obscene power requirements for one of its best graphics cards, meaning you should be able to use plenty of PSUs with this GPU and not encounter any performance or stability issues. We rounded up a few of our favorites if you need any ideas.
Corsair RM 650x
Great Value Performance
Corsair makes some excellent power supplies, and the RM 650x is a fine example. This 650W PSU is more than enough to handle the RX 6900 XT. It's also 80 Plus Gold certified, meaning it's fairly energy efficient, especially if you plan on gaming often enough on the PC. Finally, this PSU is fully modular, allowing you to connect only what you need for easy cable management. A 10-year warranty is included.
EVGA SuperNOVA P2 750
Clean & Reliable
If you find 650W of power to be a little limiting, you can always check out the EVGA SuperNOVA P2 PSU, which comes with a capacity of 750W. This may cost significantly more, but it has an 80 Plus Platinum efficiency rating, making it a far more efficient PSU. There's also a 10-year warranty, and it's fully modular for clean PC builds.
Cooler Master MasterWatt 650
Cooler Master makes some quality PSUs, and its MasterWatt 650W option comes at a great price. It has an 80 Plus Bronze efficiency rating and a five-year warranty, which aren't as impressive as the top picks, but it'll still get the job done. The 120mm fan runs quietly when not under load, and it's partially modular to help with cable management.
be quiet! Dark Power Pro 12 1200W
Have some budget to spare? Be quiet! Dark Power Pro 12 is one of the best power supplies you can buy, largely due to its construction, components used, and 80 Plus Titanium rating. You have multiple safety systems installed, and the PSU can deliver plenty of stable and reliable power to your PC. There's also a 10-year warranty.
Thermaltake TOUGHPOWER Grand 650
Did you know you can get RGB lighting inside your PSU? Well, you do now. Thermaltake decided that the PSU was too boring as a mere black slab of metal and decided to throw in an RGB ring around the fan. You won't see this within the chassis if your PSU is saving outward, but may create quite the effect by providing some light underneath your PC case. It's also reliable with an 80 Plus Gold rating and a 10-year warranty.
Choosing the best PSU for AMD Radeon RX 6900 XT
When selecting the best PSU for your AMD Radeon RX 6900 XT GPU, you need to bear a few things in mind. Firstly, for single-card use (as in you only have a single GPU in use), it's best to have a PSU with a capacity of at least 500W. For the Radeon RX 6900 XT, we'd bump this up to 600W, especially if you plan on using power-hungry CPUs like the Ryzen 9 3900X.
80 Plus certification isn't a must but does help with efficiency. Anything at Gold or above tends to be the sweet spot for PC builds, though if you're on a tight budget, a Silver or White certified PSU would do just fine. Make sure the PSU is from a reputable brand, and you'll be in safe hands. The last thing you want to do is kill the rest of your components for saving a little too much on power delivery.
Our top recommendation for the Radeon RX 6900 XT goes to the Corsair CM 650x (opens in new tab). It's well-priced, is certified for 80 Plus Gold and comes with a 10-year warranty. It'll provide stable, reliable power to your GPU and all other PC components.
If you have more money than you know what to do with, the be quiet! Dark Power Pro 12 (opens in new tab) is a solid option for a high-end or enthusiast PC build. With 1200W of power (there's a 1500W option (opens in new tab) too!), you've got everything you need for a powerful gaming rig.
