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.
In terms of total system power draw, we measured a peak of 470W in Cyberpunk 2077 when running at 1080p, with less power drawn at 1440p and 4K. Nvidia officially recommends a 700W power supply.
