GTX 570 SLI with a 750W PSU

post #1 of 21
Thread Starter 
I have a Corsair TX750W, which is a pretty decent power supply. Could it comfortably power two GTX 570s?

Also, I was wondering, if I did some mild overclocking without changing the GPU's voltage, would that increase the card's max consumption? I mean it shouldn't due to fundamental electrical laws, but then again, the situation is more complicated.

Every component of my system is detailed below.

You should be fine. Some people are paranoid, they buy 1000W PSUs for systems that use 500W max.

However I don't understand why you would need to overclock 2 GPUs in SLI.

Overclocked or not a 570TX will work fine.

I had the same question asked of our local PSU guru Phaedrus and he told me that even overclocked two GTX 570s will run fine on a quality 750w which yours seems to be.

As for overclocking without voltage change affecting power consumption I can't say much but if it does create more draw it shouldn't be life changing.

Well I mean if I can overclock something... I will. It provides extra performance for free... and that's hard not to take.

I got a 1200W for mine, just to be on the "extremely over-safe" safe side. And so i'll likely never upgrade my psu again. (Until the 2050's)
