10 Best PSUs for RX 6800 of 2021

The RX 6800 is part of AMD’s new 6000s series line of GPUs. Designed to compete with Nvidia’s RTX 3070, the RX 6800 with its 16GB of VRAM is the ideal choice for 1440p gaming builds. So, if you’re planning to upgrade your system with this powerful graphics card, you’ll need to make sure your power supply is up to the task. That’s why we’re going to explore a list of the 10 best PSUs for RX 6800.

There’s a wide range of RX 6800 builds and each one may require a different power supply. So we’ll discuss a series of PSUs that will provide plenty of power without causing any power distribution issues.

AMD Radeon RX 6800 PSU Requirements

According to AMD, the RX 6800 requires 250W of power and therefore they recommend a 650W power supply as the minimum. Compared to higher performing graphics cards, the RX 6800 doesn’t need an exceeding amount of juice. A 650W PSU should cover most midrange setups as long as it comes with two 8-pin PCIe connectors. However, leaving some headroom for overclocking or future component upgrades is always recommended so you should go for a 750W PSU if possible.

Furthermore, when looking at PSUs we want more than just raw power. Every good PSU should have a full suite of protections to avoid any risk to your hardware, and it should be reasonably efficient. A minimal efficiency rating of 80+ Bronze is recommended, though a Gold rating is usually the sweet spot. Finally, we want a solid 5 to 10-year warranty as proof of the manufacturer’s trust in their PSU design. Anything more than that, such as “silent operation mode”, is a bonus.
