what power supply would i need for this video card: http://www.tigerdirect.com/applications/searchtools/item-details.asp?EdpNo=1596804&Tab=5 and this motherboard and processor: http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=1578647&CatId=0
atleast a 480w decent psu, antec,tagan,ocz etc. with a native 24pin power connector for the mobo and pcie connections aswell
As chemo says - a quality (emphasis on quality; good brand names are Tagan, OCZ, Enermax, PC Power and Cooling, Hiper) 480 watt or great supply will run that rig without problems. The Tagan TG480-U22 runs the system in my signature just fine Do NOT buy a generic power supply. £15 for for 600W is too good to be true, and you run the risk of irritating problems as well as the possibility of large bangs (I've seen it happen).
Antec Truepower-II 430w should cut it, I'd get at the 480w to be safe at least. And for everyone's sake, get it at Newegg, not tigerdirect. Indeed, take note of my quote in shadowed's sig just above...
