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.

Sometimes you need more power to make sure it’s safe to overclock your gear or to upgrade it in the future. This is when getting an 850W PSU like the Asus ROG Thor 850 is a good idea.

Asus isn’t known for their line of PSUs in particular, but they do offer a few solid options. This Platinum-rated PSU is rich in features and the only thing that can hold us back from purchasing is the price. If we can get past that, what we’ll get is a modular power supply, packed with ROG heatsinks and a silent 135mm winged-blade fan. Optionally, we can press the 0dB button to turn off the cooler while the PSU operates under a light to medium load. As for its design, it’s certainly sleek and modern-looking, especially thanks to its OLED panel which displays how much power is drawn by the PSU.

In addition to these features, we get to enjoy Thor for 10 years without stress, thanks to Asus’ warranty and support. So budget aside, Asus ROG Thor 850 is easily one of the top choices for an RX 6800 XT setup.

4. CoolerMaster MWE Gold 750

Key Features

  • Up to 90% efficiency
  • Modular flat cables
  • Low-noise LDB bearing fan
  • Good thermal resistance under full load

CoolerMaster offers a good balance between price, performance, and features with the MWE Gold 750. This 750W PSU is rated with Gold for efficiency, which is considered by many to be the sweet spot, and it’s entirely modular. But unlike a lot of modular PSUs, this one comes with flat cables, which take up less space, are easier to arrange inside a tight case, and improve the overall cooling of the computer. Furthermore, the MWE Gold is a quiet power supply thanks to the LDB bearing fan.

As for support, CoolerMaster offers a 5-year warranty, which is less than what other manufacturers have to offer. However, that’s possibly one of the reasons why this PSU is on the cheaper side.

5. NZXT C750


Form factor: ATX | Capacity: 750W | Efficiency rating: 80 Plus Gold | Modularity: Full | Warranty: 10 years

Key Features

  • Fully modular with sleeved main cables
  • Compact size with 150mm-long casing
  • Zero noise fan mode cooling switch
  • Fluid dynamic bearings

As another solid Gold-rated PSU on our list, the C750 fits the requirements of a typical RX 6800 XT setup. Its power output is stable, it’s entirely modular, and the manufacturer supports it with a 10-year warranty. As for its size, it’s smaller than the typical 750W power supply, which is both a good and a bad thing.

Due to its compact size, the manufacturer chose a 120mm FDB fan, which is silent only under normal loads. Once the PSU is under full load, the small fan begins to struggle and it starts making some noise.

All in all, the C750 is a good choice for a midrange build due to its ventilation shortcomings. Heavy gaming or demanding rendering operations might stress it too much.

The Asus ROG Strix 750 is a 750W PSU with a Gold-rated efficiency that offers enough power for a standard, not over the top RX 6800 XT build. This fully modular power supply is silent, efficient, and good looking. While it’s not as impressive as the Thor line from Asus when it comes to features, the Strix version comes with everything we need. It has 0dB cooling mode which is automatically engaged during light load, and it’s cooled by a robust 135mm fan that will stay silent even under heavy load.

The interior is as impressive as the sleek exterior since Asus is known for using premium-quality hardware, including the highly-rated Japanese capacitors and ROG heatsinks. As for support, the Strix is under a 10-year manufacturer guarantee. If 750W is all we need, this PSU is one of the top choices, though it might be a bit pricey for those on a strict budget.

8. CoolerMaster MasterWatt 750


Form factor: ATX | Capacity: 750W | Efficiency rating: 80 Plus Bronze | Modularity: Semi | Warranty: 5 years

Key Features

  • Thick 16AWG PCIe cables
  • Low-noise LDB bearing fan
  • Fanless operation up to 15% load

The MasterWatt 750 is a good quality power supply for those who are on a budget. It offers plenty of performance and reliable features for its price. Despite its Bronze-rated efficiency, this PSU is well-built and it will sustain a midrange RX 6800 XT build. However, it is semi-modular, but lacking full modularity shouldn’t be too much of a big problem since we can put aside all the peripheral cables we don’t need.

As for features, the MasterWatt is equipped with fanless operation up to 15% load, which isn’t much, but it will keep the PSU as silent as possible when performing simple tasks. When engaged, the fan is quiet, especially when considering it’s only 120mm in size.

In essence, MasterWatt is an excellent choice for systems built on a budget.

9. Thermaltake Toughpower Grand 750W
