Nvidia RTX 4080 Founders Edition 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.

Total system power draw hit a peak of just under 500W in our testing, and that was at 1440p resolution. This will vary depending on the exact game due to CPU load (we use Cyberpunk 2077), but it is clear to see the 4080 does not draw as much power as the RTX 3080, despite sharing the same 320W rated TGP. Nvidia officially recommends a 750W PSU.
