ehabash1I wouldn't if you plan to overclock at all.If stock then you should be fine
kringyou are 100% totally fine. I have similar rig and have a 3090. and when I run the power test in the new version of Precision X1 it says only 702W are max draw and EVGA recommends a 750 Gold or better. so with a 3080 you are totally fine with a quality 750, and that's even with overclocking. go ahead and grab PX1 184.108.40.206 and there's a new feature at the top with icon POWER. run that to confirm.
ehabash1can you download gpuz and or HWinfo and check some of your power draw?the 9700k is pretty power hungry but stock doesnt pull THAT much. Since there are so many variables like are you watercooling at all? pump needs power. Lots of fans or only a couple? You should probably be fine but if i were you i wouldnt try messing around with 450watt XOC bios for the 3080. stock bios even if you overclock the gpu i think you will be fine but you should check your current power draw to make sure
EpicSurvivorSo I plan on getting an FTW3 RTX 3080 and wanted to get some input. I have an EVGA SuperNova 750 G2 PSU was wondering if that would be enough or if I would have any issues? The rest of the specs are 9700k (Stock) 16GB RAM, One 2TB HDD and One 1TB SSD. Motherboard AORUS PRO Z390. EDIT: I need to update the signature.Thanks

EDIT: I need to update the signature.Thanks As long as you don't use the 450W BIOS OC, that's fine. They recommended 850W if you updated the BIOS to the 450W, anything else is fine with a 750w.
RobobI have overclocked CPU and GPU together on 750w with 3090 and I’m running good so far.I don’t run optical drives anymore but just have 3 ssd and fans.As others stated as long as you don’t load the extreme O/C 450w bios you should be good.
mchang1984The best time to buy a PSU would be Black Friday though. I bought an EVGA 1600W T2 last year for $150 from EVGA during black friday. Best Deal ever. 750W is probably OK, but you can never go wrong with better efficiency with a higher PSU.
mchang1984That said, that also means that a 1600 W PSU is also NOT going to pull 1600 Watts from the wall 24/7. But what it can do is provide much better efficiency since your system is using between 500 Watts to 750 Watts of power and 1600W divided by 2 is 800 Watts so that is still much more efficient power conversion than a 750W PSU.
