Upgrading your graphics card can sometimes mean upgrading your power supply, especially if it’s one of the latest generation flagship cards like the AMD Radeon RX 7900 XTX. If you want to make sure everything is smooth and stable, it’s best to check if your current power supply can handle the upgrades offered by AMD’s new range of GPUs, called the RDNA 3 or Radeon RX 7000.
So far, the new GPU range has only two cards: RX 7900 XTX and 7900 XT. Of the two, the RX 7900 XTX is the more power hungry. Even then, it’s still pretty conservative compared to Nvidia’s flagship RTX 4090. In Nvidia’s case, the Founders Edition has a total board power (TBP) of 450 watts and requires an 850 watt PSU. However, some of Nvidia’s board partners who have built custom versions of the GPU require much more powerful power supplies, going up to 1200 watts.
In the case of AMD’s RX 7900 XTX, it won’t be too bad. AMD focuses heavily on performance per watt, which means that RDNA 3 packs a lot of power with relatively little power. Even then, you still need a solid power supply to ensure everything runs smoothly.
If you’re going to use one of AMD’s best graphics cards, you probably pair it with a great CPU, and those things add up. Below we’ll talk about some of the best power supply options to pair with AMD’s new flagship GPU, so dive in and pick yours.
What power supply do you need for AMD Radeon RX 7900 XTX?
AMD’s Radeon RX 7900 XTX, while a powerful GPU in its own right, isn’t overly demanding when it comes to power consumption. The card’s TBP is set at 355 W, which is almost 100 W less than Nvidia’s RTX 4090.
This is not unexpected: AMD’s flagship isn’t really of the same caliber as Nvidia’s RTX 4090. Instead, it bills itself as a rival to the Nvidia 4080, which actually uses less power with its 320W TBP. On the other hand, AMD’s second-best GPU has recently experienced an earthquake when it comes to power requirements. As a result, the RX 7900 XT now has a TBP of 315 W.

Although AMD has yet to release an official recommendation when it comes to the RX 7900 XTX power supply, there are some safe bets you can take right away rather than wait for AMD’s opinion on the matter. Before we get to that, it’s important to note that AMD’s motherboard partner Asus recommends between 850 W and 1200 W, and our recommendations fall within that range.
The absolute minimum for the RX 7900 XTX will be a 750W power supply. Going up to 850W gives it a bit more breathing room and is probably a safer option. Keep in mind that AMD partners can ask for even more than that, so if you’re building a beast, going with a 900W to 1000W power supply is probably a good idea.
Privateer
Now, let’s start at the top. If you want a great 750W power supply for a budget build, the Corsair RM750x is a good choice. This is a 750W Gold PSU. Corsair has a great reputation when it comes to their cooling and power solutions, so you’re making a good choice here, and it’s only around $120 at the time of writing. this article.
EVGA
EVGA may have given up on making GPUs, but they still exist and make some solid power supplies, along with other components. An example of these excellent components is EVGA Supernova 850 G7. This 850W Gold Plus PSU is efficient, supporting an RX 7900 XTX and a good processor, and is quite affordable at just $70 more than the 750W Corsair.
If you’re not a fan of EVGA, some other good options for 850W power supplies include or haggle.
Seasonal
Assuming you always want to err on the side of caution, you can choose a really powerful power supply that will leave plenty of headroom and help future-proof your equipment. This is not required at all for the base RX 7900 XTX, but some of AMD’s partners may require you to use a similarly powerful PSU. In any case, this is most likely overkill, but it could be useful for higher-end PC builds.
If you’re willing to spend around $320, the Seasonic Prime TX-1000 is a fantastic 80+ titanium option. It’s quiet, reliable, and ready to power an enthusiast’s gaming system. It is also expensive.

Asus
We’re now in the big leagues with various 1200W power supplies. Like the 1000W options, these will be overkill for most RX 7900 XTX based systems. However, since some of AMD’s partners really demand that kind of power, you might want to go all out and go with a 1200W PSU to secure your build for years to come.
As long as the $400 price tag doesn’t put you off, one of the best PSU options in this category is the Asus ROG Thor 1200W. This 80+ Platinum certified power supply is quiet and reliable when your system really needs all that extra power. With this power supply, you can easily pick up one of the best CPUs on the market (even the most power-hungry Intel models), add all the RGB lighting you can dream of, and still have plenty of power.

AMD avoided a potential fiasco
Jacob Roach / Digital Trends
AMD uses a standard 8-pin connector for its latest graphics card: two, to be exact. Some models, especially those made by AMD’s motherboard partners, may use three connectors. Still, that’s good news for you, the person building the computer, because you won’t have to mess with new technology for something as crucial as achieving a constant flow of electricity.
Nvidia’s latest flagship, the RTX 4090, as well as the RTX 4080, are based on a 16-pin connector. Since most power supplies don’t come with one, Nvidia has connected its GPUs to a 12V HPWR adapter that is designed to deliver up to 600W of power over a single cable. Unfortunately, you didn’t anticipate the fact that bending the wire could cause serious thermal problems.
As a result, some users experienced something quite scary: their adapters and connectors caught fire and completely melted down. AMD seems to have made the right decision by avoiding the 12HVPWR adapter, which is still under investigation by Nvidia.
Better safe than sorry
When choosing a power supply, it’s always best to leave some leeway. You never know what updates you might get in the future. You could also end up overclocking either the GPU, the CPU, or even both, and that will put extra strain on your power supply.
It’s easy to treat the power supply as an afterthought and try to pick something cheap, but trust us, it’s not worth it. A computer without stable power will do you no good. It’s better to spend a little more on a Gold or Platinum power supply than regret it later if something goes wrong.
However, there’s no need for anything completely over the top. It’s best to add up the potential power consumption of your components, and then leave some extra headroom. There are PSU calculators online that can help you with this, like this one created by Newegg.
If you’re running an AMD Radeon RX 7900 XTX in your next build, any of the PSUs mentioned above will work just fine, but if you’d like to check out other options, be sure to check out our roundup of the best PSUs on the market right now.
