580 sli PSU ACTUAL Wattage

post #1 of 6
Thread Starter 
ok so i have seen the guru 3d review of 580s in sli. according to them they were pulling 719watts FROM THE WALL. my current setup in my sig will draw 496 watts from the wall with prime 95 across 8 cores and my gpu maxed out in design garage demo. so to be safe lets say 500 watts and my psu has a 83% efficiency, once again to play it safe 500*.85=425watts on the psu. so if i threw in a second 580 at a highballed 280 watts that would put me around 705 watts and thats if the cpu and both gpus were MAXED which will never happen in gaming.

Has anyone on here pulled off a pair of 580s in sli with a pc power and cooling 750? on paper it seems like it would be fine, i am more than aware of the risks involved of pushing a psu as i have popped a couple in my time. i know i would not be able to OC at all or very very little. i do plan on picking up a 1200 watt corsair in a few months but for now i just wanna get another 580 and water cool it so im ready for BF3 and some added insurance for skyrim although i doubt skyrim will need it.

please note that my psu is rated at 750 constant use and 825 max. i know that cap aging can cause some loss aswell.

EDIT:496 from the wall is with the gpu@ stock speeds. speeds listed in sig it will break just over 600watts.

You can go sli 580s on that psu with a mild OC, no doubt.

It would work, but I'd say a medium-high overclock would take it to its limit.

That psu looks to be rated for 60A on 12v (~720W)and the total peak draw is 825W, so it'd chug along, but I'd recommend something a bit beefier.

Well you certainly know how it is. I'd say it'll be fine, just dont go pushing those gpu clocks too much.

Aight, thnx guys. i just wanted a little extra reasurance. if i do blow it i will post carnage pics...because we all love those.

I already have a EK block on my current 580. anyone here ever used their sli bridge that splits the incoming coolant off to each card so that each card gets fresh coolant??does it work well? or would it be better just to have the higher flow of runing them in a series. i can post a new thread in cooling if no one can answer this
