well iv been running sli'ed 7900gtx's for a while think my psu may be holding me back or shold the 580 be eonugh ? does anyone have that cool little web link that has all the hardware on it to tell you how much power your system uses?????
Thats crap, apparently I need a 460w PSU for my Pentium D system yet I am using a 430w 100% stable with a solid 12v rail. the 580w Tagan should be enough for most systems, even the Quad SLi rigs Nvidia showed only had 650w PSUs I believe.
