580 SLI 850W Unit?

post #1 of 14
Thread Starter 
So my CPU uses around 150w full load.
The 580 uses about 250w in games at most. Times that by two.
Do you think it will be fine? I don't plan to OC the GPU's.

850W is pushing it for two of them. You should be alright, but I would be weary of overclocking them.

it should be fine but if you're worried snag a 1k Watt.
couldn't hurt to have more than enough but it can to not have enough

It will be N.o.P.r.o.b.l.e.m

Take into account that the HX is gold efficient.

I'm sure 850w would be fine

I'm running two GTX480s in Sli. Both overclocked 10% ish!
And have no problems at all
--------------

If you was going to be folding, then I'd say 1000w!
But for what we do, 850w is fine imo

Well i don't plan to overclock them and even if my CPU and GPU's are at full load, my estimation tells me it will be fine.

Gold Efficient? Am sure it said silver on the box.

Seems like you missed this out

The HX850 is gold efficient (really near the AX850 unfortunately for me ), but is certified for silver, as I think Corsair does not want to have any problems as some units do not reach the gold efficient mark I believe.

Efficiency just saves your power bill thats it....


OP: 850w will be fine as long as your not really overclocking much on them

You'll be able to OC to 950core on two 580s on a HX850 no problem at all, if you decide to go that high.
