If you are new to premium custom PC building, it can be hard to know what parts to pair – especially when looking for the best PSU for an RX 7800 XT. AMD has reliably put out great graphics processors for several generations now, with a sterling reputation for great gaming graphics cards, so it is no surprise that the RX 7800 XT, is the perfect mid-range RDNA 3 GPU. It is still important to in an appropriate PSU that meets the 7800 XT’s power supply requirements.

Thankfully, we’ve already compiled a list of the best 7800 XT power supply units, so that you can spend less time wondering what to buy, and more time assembling your newest PC build! With options across a range of power supply needs and budgetary limits, our top picks should be perfect for you no matter the build you choose!

AMD RX 7800 XT Power Supply Requirements

The 7800 XT draws on slightly more power than the 7700, being a slightly more powerful GPU. AMD recommends a PSU with a wattage of at least 700W, as the RX 7800 XT draws around 263W on average. This sits right between two common power supply wattage specifications, with a 650W PSU being too low and 750W being a touch above what you need. However, we always recommend overshooting your power supply requirements: not only does it mean that you will always have enough power for your current PC components, but for future upgrades as well.

That said, a 750W PSU will be serviceable for the 7800 XT: GPU manufacturers tend to overestimate the power drain of their components as a precaution. However, do consider a long-term investment in your PSU for the 7800 XT, as the best PSUs can last you through several generations of other PC parts.

FAQs

Is it bad to have a high-wattage PSU?

There are no issues with having a PSU that has a higher wattage than you need, in fact we actively encourage punching a little above your PC’s weight, but having a PSU with wattage that is too low can cause damage to your PC.

Is an 850W PSU good?

For most modern PSU builds, an 850W power supply will be plenty for all components to receive the right amount of power. Though there are wattages as high as 1300W for PCs, these are generally overkill for the average PC build.
