PSU for 3080

[Zini]

So i know for a fact that NVIDIA is saying that a 750w psu is recommended for the rtx 3080 but i was wondering if it's actually enough so if anyone with experience or with the knowledge could tell me like how much overhead do u calculate for with a 750w psu with a 3080 or is it just really really tight with a 750w psu?

I'm using a 650W PSU and all is good for now. I'm not overclocking neither GPU nor CPU.

650w is already enough in most cases unless you start overclocking a 9th or 10th gen Intel CPU, 750w is more than enough in most scenarios

I may buy a 3080 STRIX, it has 3 x 8 pin, my PSU is a 750W Focus Plus, only got 2 x 8+8 pins.

On Asus' website they say a 850W PSU is needed.....

So that's 4 8-pins in total, enough for the 3080 Strix or any other GPU.

Just 2 wires from the PSU.

As long as it's not a really cheap PSU, If a cable has 2x8-pins running through one cable, then that cable is also rated to carry 2x8-pin power through it. The PSU cables are designed to carry that load, it's not going to damage anything or overheat or catch on fire.

It's a year old Seasonic focus plus gold 750W

I’d suggest starting a new thread in the Cases and Power Supplies sub forum. If it remember correctly, that had some issues with extremely high power draw GPUs.

in that case i think im fine with my Corsair RM750x
