Prev card 2080S (oc'd) and rest of spec in sig drew 520W peak from the wall when folding, more than any game.
My 8-9 yr old AX860 blew up when I booted RDR2 with the 3080, loud BANG. Pretty scary and worried i'd damaged the PC obviously.
Got a STRIX 750W PSU from OCUK and installed today. Booted and luckily PC and GPU all fine YES!
So what I've seen so far with +100mhz on the core is 722W peak from the wall!
Thankfully there's the safety margin of multiplying by about 0.9 to obtain true power used inside the PC, owing to PSU efficiency not being 100%.
However it is RIGHT on taking 450W as quoted as I measured my CPU folding and it took 215W. I haven't even got her under water yet and flashed the XOC BIOS and pushed it.
THESE GPUS ARE NO JOKE PEOPLE.
They are the second coming of Fermi. Batton down the hatches, get a GOOD PSU.
NB this is most I could capture, app is annoyling not in realtime you have to get snapshots from the smart plug:
