Since the Nvidia Ampere Keynote, we've known the RTX 3080 and RTX 3090 are going to be absolute power suckers, Nvidia itself recommends a bare minimum of a 750W power supply for the RTX 3080 and RTX 3090, but you'll need larger power supplies for some systems. Our testing backs that up, too; we observed up to a 335W average power draw from just the 3080. This means many of us will need new power supplies, unfortunately right during a PSU shortage that has sent pricing skyward on some models (more on that shortly).
NVIDIA RTX 30 series is aggravating PSU shortage
