We measure system-wide power draw from the wall while running Cyberpunk 2077 for 30 minutes at 2160p (4K) resolution.
For a quick look at total system power draw, my test rig with an i9-13900KS pulled below 400W with the 4070 Super, when running Cyberpunk 2077 at 4K. Of course this will vary depending on the CPU and game, though Nvidia does recommend a 650W power supply.
