2080ti with 650w psu

[CHEESYnachoMAN4]

I have a 650w psu and I wanted to upgrade my gpu to a 2080ti but I was wondering if I would also need to upgrade my power supply or is 650w is enough.

My cpu is overclocked to 4.5ghz.

Is it the EVGA P2 650W listed in your signature? That's perfectly fine for a 2080Ti. No need to change.

Yes it is. Im glad it works. Will it still be ok even if im running a aio on my cpu and im gonna overclock both cpu and gpu?

Yeah, it'll be fine.
I have a 6700k and a 1080Ti (similar power requirements to the 2080Ti) and when pushing 4.9GHz at 1.5V 4.8Ghz at 1.4v on the CPU in games and benchmarks I was looking at around 500-550W power draw from the wall (so, 450-500W DC after efficiency loss). From memory I think that even had a mild OC on the 1080Ti as well.
You're not going to have any issues.

Edit: Found my old status update post where I did the testing...  Didn't test power consumption in games at 4.9GHz (wasn't really stable), but was at 4.7-4.8GHz at ~1.4v

Spent less time playing with the GTX 1080ti, but had the GPU Core clock at 1730MHz (was boosting to 2025MHz/2034Mhz(?) in games) and Memory at 11230MHz and had the power limit set to 150%. I knew these figures were stable from previous fiddling so I just went with them. Didn't even bother trying to run games at 4.9GHz, but at 4.8GHz @ 1.395V I did a few game benchmarks. With the GPU and CPU overclocks, GTA V peaked at about 470W measured at the wall*, while Metro Last Light benchmark peaked as high as 520W from the wall* and was averaging 450-500W depending on what was happening on screen during the benchmark.

as long as ur not one of the 500w tdp cards you are fine, even then it SHOULD work
