Is 750w psu okay for a 4070ti with overclocked cpu?

Silverbackk · February 11, 2023

Hi all, looking to put a 4070ti in my current rig. Just sold my 2080 super that was in there. I have a 750w Corsair hx750i psu and was wondering if that’s going to be sufficient for the 4070ti? Have a i7 10700k oc’d to 5.1.

Also do you think there will be much of a bottleneck at 1440p? Or am I good?

Cpu: Intel 10700k

Motherboard: Gigabyte Z490 master

Ram: Corsair vengeance rgb pro 16gb

Gpu: …

Case: Nzxt 710i

Cpu cooler: Nzxt x73 360mm aio

Power supply: Corsair Hx750i platinum

Storage: Samsung 970 evo plus 1tb

Storage: Samsung 970 evo plus 500gb

Storage: 860 evo 250

Storage: Other 120gb ssd

Storage: 2x 1tb hdd

TIA.

Yes. I am using a Corsair RM750i with an overclocked 7700x - 32GB DDR5 - RTX 4080. max wattage I saw was around 480 total.

Jeez that’s interesting. Yeah main reason being was the fact that the cpu is overclocked. At least I won’t have to upgrade the psu then! Thanks.

The power shouldn't be a problem. The 4070Ti isn't that powerful and has basically the same power draw as the an OC 10700k, so you shouldn't poke above 450W in total.
