Gamers have been eagerly anticipating the launch of AMD’s new RDNA4 GPUs ever since Nvidia’s been struggling to keep itself afloat amidst the trilogy of catastrophic issues haunting the RTX 50 Series launch, which includes, but isn’t limited to the BSODs, melting power connectors, and missing ROPs.
But enough of Nvidia for now. Thankfully, the AMD Radeon RX 9070 and RX 9070 XT officially launched worldwide on 6th March 2025, and I’m delighted to inform you that you can actually find both GPUs in stock at prices similar to the MSRP, which is more than can be said for Nvidia’s RTX 50 GPUs, which are becoming increasingly difficult to source, even at 2-3x the MSRPs thanks to stock shortages.
The RX 9070 and RX 9070 XT sport TDPs of 220W and 304W respectively, which seem very tame next to Nvidia’s monstrous Blackwell GPUs’ power requirements. Plus, in our RX 9070 review, we saw that the card not only performs exceptionally well, but its power consumption is also rather decent, as it was taking around 250W on average during heavy load. On that note, we have worked night and day and spent several weeks testing and reviewing a variety of PSUs to round up the five best power supplies for these GPUs.
Here’s an overview of our selections along with a brief breakdown of each of their specs.
Before you proceed further, I’d strongly advise you to give our PSU Watts Calculator a trial run. It’s an in-house tool that’s been designed specifically to help you choose the most suitable PSU for yourself as per your gaming PC and its specific components.
