I just RMA’d my card. Two PSUs over 750w when calculator says 550w and still restarting. My enthusiasm for these cards slammed into a wall.
I know my system pulls a lot more than that... With the 3080 FTW3 Ultra. (And 2080Ti FTW3 Ultra)
Plug yours into the Seasonic calculator, it's at least pretty accurate.
My actual max power draw is 700W from the PSU to the system, that's not from the wall.
Not including power spikes.
Gaming loads are between 550W and 600W depending on the game, not including power spikes.
GPU not overclocked.
