Every watt eating component is listed in sig rig I'm pretty sure. (I do have 10 fans in there though)

I downloaded furmark but haven't ran it yet. I don't see the point, but I might sometime.

That's a heavily OC'd 580 too, Usually running 940mhz-954mhz @ 1.125v

lol I ran two overclocked Radeon hd4870, an overclocked Phenom 720be, then 965BE, 8 x 120mm fans all off a Corsair VX550W. Ran it for about a year issue free before upgrading.

Oh yeah, you should have a lot of headroom for an OC. Post your OC's once you get a stable one going!

And I've found that I don't get any gains overclocking Memory, but the game seems to run smoother IMO.

Placebo? Maybe.

But I only game at 1920x1080 and usually run everything maxed out so any little increase I can kind of see since I run Fraps and such to keep track of everything.

Yep, check out what my Antec truepower 550w can do. Needless to say, its powering my eVGA GTX 570 SC @ 850/1700/1990 and i5 2500k @ 4.6ghz with no issues.

Haters can hate, but Antec still makes quality PSU's

And that's what they recommend I guess, you can actually power 2 580's on a quality 750w PSU with no OC.

Just no FurMark or anything like that.

been a while, but what program you used to overvolt it? is that 1113v safe?

All sounds normal, my sig rig cpu oc'ed to 4.7Ghz stable and GPU oc'ed to 850Mhz core is running off a 500W thermaltake psu. Pulls up to 620w from the wall cpu and gpu under full load synthetic.

750w is enough even for overclocked SB/580s
