AX750 Enough?

post #1 of 8
Thread Starter 
For my sig rig and an SLI gtx 580 + WC?

I would be comfortable with 900w psu but 850w would do it. I think you will be cutting it close with a 750.

As long as you don't push the overclocks and then try to max out power consumption with like LinX + Furmark, a 750W unit should be fine. Under gaming loads, you'd be under that for sure. Even then, the worst that should happen is that the unit would turn itself off.

And we're talking about an AX750, which is definitely something you should be babying. If you can get an AX750 to die by overloading it, you should get an award.

Actually, your award would most likely be another AX750, since it'd be under warranty.

You should be fine and i think the AX750 can run all Sli set up.

the only OC I plan on doing with this setup is most likely a 5.0ghz OC and thats it.

You will definitely fine. I ran a 5970 and a 5870 (3 GPUs total) + my sig rig on my old AX750 and it ran without a sweat.

This ^^..

A stock GTX580 uses ~ 220W in games.. CLICK HERE (look at the Peak= 229W and Average= 214W in Crysis 2)

So I would say YES!!
