Though the Radeon RX 6800 XT has been surpassed by AMD’s newer GPUs, the graphics processor is still a capable PC component, when paired with the right power supply. The best PSUs for RX 6800 XT PC builds give you reliable power supply without overheating or being too noisy, for professional or gaming PCs to run as smoothly as possible. Choosing a product that meets the RX 6800 XT PSU requirements is crucial, but in this buyer’s guide, we’ve also made some future-proofing precautions. A PSU is a part you should buy once every three years rather than three times a year; so we’ve chosen 6800 XT PSUs that will guarantee longevity, stability, and quality.

RX 6800 XT PSU Requirements

AMD lists the RX 6800 XT power supply requirements as starting at 750W, with the GPU itself taking on 300W of that total power. If you have a demanding CPU or other components, it may be worth double-checking what overall power you need using a PSU calculator. Regardless, we always encourage PC builders to go a cut above what they need when upgrading to a new PSU. Parts such as graphics processors come and go, and with the 6800 XT wattage being as low as it is, a lower-spec PSU will have to be replaced as soon as you want to play more recent releases. We’ve selected a range of power supplies, with wattages that match or surpass the 6800 XT PSU requirements, in order to future-proof your next PC build.

We hailed the Corsair RM850x as the best 850W PSU on the market, and for good reason: this PSU is affordable, efficient and gives just the right amount of headroom for upgrades. The RM850x comes with a Zero-RPM fan mode for smooth and near-silent running on all but the most computationally demanding settings. Another 80+ Gold-rated power supply for the 6800 XT, the PSU keeps ongoing costs low whilst also having a reasonable upfront cost.

For a more affordable 850W PSU, the Thermaltake Toughpower GF1 is a reliable budget option for those wanting extra wattage. One of the few budget power supply units that is ATX 3.0 and PCIe 5.0 compatible, this fully-modular PSU runs smoothly and near silent, and gives you headroom for future upgrades. Though the cable management itself is somewhat ruined by poor cable quality, they are the only thing this budget power supply loses points for. For affordable and efficient power supply for the RX 6800 XT, the GF1 is hard to beat!

750W

Certification

80+ Platinum

Modular?

Yes

Pros
  • Hyper-efficient PSU
  • Silent running
Cons

On the other hand, if you are after the bare minimum wattage in your RX 6800 XT PSU, then the Straight Power 11 matches the power supply requirements to a fault. The only PSU on our list with 80+ Platinum efficiency, this power supply module runs staggeringly quietly. With an internally wire-free design and fully modular build, the Straight Power 11 can be easily inserted into nearly any PC build. You’ll have to pay a bit more for this PSU, however, and at only 750W it isn’t particularly future-proofed. But for the most efficient 6800 XT power supply, we find the Straight Power 11 hard to beat!
