Wanting to SLI, request your assistance...

post #1 of 12
Thread Starter 
Hey guys, I have the opportunity to pick up another GTX 580 for cheap, but I am unsure if my psu can handle it. I have the Enermax RV920 920w psu. My 2600k is oc'd to 4.5ghz @ 1.35v, my GTX 580 is oc'd to 875mhz core and 2175mhz memory, running 2x 4g 1866 ram @ 1.6v, 2 optical drives, 1 ssd, 3x 2tb WD black hdds, and 6 fans. The 580 that I have the chance to pick up cheap is a reference EVGA card. I have checked out a couple different psu calculators and some give me the ok and some recommend more power. If you could help me out with some info so I can determine if this psu is enough I'd greatly appreciate it.

Edit: I should add, this is a gaming rig. I generally do F@H on it when I sleep and when I am not at home. No other intensive tasks are performed.

I think you will be fine with the 920 w psu.
I'm running alot more than that on a hx1000.
I've got 2x 295's which I think use about the same or even more power than the 580's
running a heavily oc'd 920, pump, 13 fans, 2x295, 1x 240, soundcard, 2x ssds, 4x hdds, 2x optical, 6gb heavy oc'd ram, lights,...

If it's a quality psu, then I personally think that you're good to go smile.gif

Your PSU can handle it easily.

PSU should be fine, until you extremely overclock the cards.

Thanks for this fast input so far guys.
@ XFZhong: I don't think I'll be heavily oc'ing the cards due to the 2nd 580 I'd be picking up having the reference cooler.

I don't want to spend the money on water cooling. I have a good air cooled setup atm. Maybe someday in the future, but I always end up buying new hardware when I get the extra money, instead of buying water cooling parts.

Go for it!
As for overclocking two GTX 580s in SLI:
Why would you even need to? The performance will be ridiculous

You're on OCN man, can never have high enough clocks. tongue.gif

I want SLI because I rock dual monitors and a lot of games are hard to maintain high fps while using a second monitor.
