SLI GTX 670 PSU

aaawew · Jun 28, 2012

I'm fairly sure that two GTX 670's can be run with a 850w PSU but I am just looking for some confirmation or different news

So can it?

It could be run on a 650W PSU (while overclocking the snot out of them and the CPU). Hell they could be run on a 500W PSU.

So yes, 850W is plenty.

Really they could run on a 650w? I remember being told that 850w is pushing it for SLI 570's but that could be wrong too, I know that 670s are more power friendly than 570s but now i'm just confused xD!

Yeah, a 850w psu is more then plenty for two 670s in sli. I have mine on a 750w psu but that was because I needed the extra pci-e cables for them.

Like the great Chuck D said, "Dont believe the hype". :clap:

GTX670 = 141 nominal 170 peak
GTX570 = 219W

Even peak v peak its 100W difference. Nominal v 570 is ~160W.

Actually I remember reading a review that noticed that the power consumption of 2 GTX670 was similar to that of a single 570.
