The GTX 480 does consume a lot of power, possibly an 800W PSU might be needed if you have an o/c i7 for example. m 0 l Bluescreendeath a b U Graphics card a b ) Power supply June 4, 2010 4:58:25 AM A GTX480 uses as much energy as a GTX295. I suspect a GTX480 + GTX260 uses as much energy as 3x GTX260s. 1 GTX480 and a system uses ~506 watts at load. http://www.techspot.com/review/263-nvidia-geforce-gtx-4... A GTX260 adds about another 150watt at load. So I would say go for a quality 800watt PSU and a 850+watt PSU if you want to overclock. m 0 l Related resources What wattage power supply do I need with a core i3 and gtx 750 ti? - Forum Power supply needed for gtx260 sli? - Forum Minimum wattage power supply for dual GTX 770s? - Forum power supply for gtx 480 - Forum GTX 480 power supply cables question - Forum Can't find your answer ?
