The RX 6800 XT is one of the high-end additions to AMD’s new line of RDNA 2 graphics cards. Built as a rival to Nvidia’s RTX 3080, the RX 6800 XT is essentially the RX 6800 taken up a notch. It has an identical number of transistors, the same 16GB of VRAM, and the same processing node. But, what sets the XT apart is the rendering configuration and higher clock speeds, which in turn demand more power. So to find out which power supply is the ideal choice for our setup, we’re going to go through a list of the 10 best PSUs for the RX 6800 XT.
Before you can find the right PSU for your configuration, you need to take into account the graphics card’s requirements, next to the requirements of your processor and other components. A midrange setup will differ from one that runs an overlocked Threadripper, for example. So make sure you take everything into account before making the purchase.
AMD Radeon RX 6800 XT PSU Requirements
As mentioned earlier, the downside of the RX 6800 XT, when compared to the RX 6800, is that it requires more power. According to AMD, this GPU requires 300W of power on its own and therefore a 750W PSU is recommended. That power demand may go further up if you decide to overclock the GPU to its limits and if you get a high-end CPU.
Furthermore, a good PSU needs to provide us with more than just raw power. When dealing with demanding hardware, we always need to think about efficiency, cooling, and having plenty of overclocking or upgrading headroom. Buying a feature-rich PSU, preferably a modular one is recommended if you aren’t too heavily restricted by your budget.
