Even otherwise though, you need 750 for a 3080
Yeah I replaced the link. I'd rather not replace the 650w if not needed and I keep reading others say their 650w works out fine for them and according to some power calculator it turned out to be 554 watts so I'm not sure.

I'm sorry but I STILL can't find the link 😂 650 is walking the edge basically, you got no headroom theoretically it should be like

65+325+150 + 30 or 40 that's about 580 under 100% load. You can probably get away with it

Yeah I accidentally fused it with other text. Should be fixed now. I just really don't wanna spend another $100 on a better power supply if I don't have to. Is there any risk of damage if I just plug in the 3080 and test it out?

Nah I don't think so. Most that can happen is it'll shut down probably

Wish I could disagree and say your 650w PSU would be ok, but hes right, you need a GOOD 750w unit.

The max power draw is higher than my RX Vega 64 which in some games would hit OCP and crash on a Seasonic Titanium 650w PSU. I replaced it with a 750 and no problems since.
