AMD RX 7900 XTX Review

We measure system-wide power draw from the wall while running Cyberpunk 2077 for 30 minutes. We do this at 1080p, 1440p and 2160p (4K) to give you a better idea of total system power draw across a range of resolutions, where CPU power is typically higher at the lower resolutions.

As for total system power draw, we test a range of resolutions to give you an idea of what to expect. This does vary from game to game, as of course CPU load is included in these figures, but we're looking at 580-610W in Cyberpunk 2077 so that gives you a good idea. AMD officially recommends an 800W PSU.
