You want to hear something wild? I've got a Ryzen 3600/GTX-1080 system that runs on a 450w power supply.
3600 and the 100 are like peak efficiency. I had my 1080 undervolted so it used just under 180 watts, and even my 5800x3d used maybe 100 watts at any given moment outside of 100% load.
Honestly though a 450 watt power supply is probably just old/low quality at this point. I'd be more worried about the PSU blowing up randomly, than the PSU blowing up from being over loaded.
Yeah I kinda wish I hadn't done that. It's a Corsair SF450 small form factor PSU, they don't even sell it anymore.
I built this rig during the GPU shortage, I stole the GPU out of an old computer a relative was retiring. The CPU was chosen for TDP more than anything else, small form factor case without much room for heat sinks meant a power ceiling.
