05Track Posted September 27, 2010 Share Posted September 27, 2010 I'm sure this has been posted before, but I cant seem to find any definitive answer through search. Will a HX620W have enough juice to power a GTX480? I'm currently running a GTX 280 OC2 and am just planning to upgrade this only. Nothing fancy with the rest of my system, just 2 HD's and mildly clocked C2D. Thanks. Link to comment Share on other sites More sharing options...
hypermog Posted September 27, 2010 Share Posted September 27, 2010 HardOCP says you should get the HX750 for a single GTX 480 Link to comment Share on other sites More sharing options...
uscavman Posted September 27, 2010 Share Posted September 27, 2010 I think the GTX 480 eats up about 42 amps per card. Link to comment Share on other sites More sharing options...

Corsair Employee RAM GUY Posted September 27, 2010 Corsair Employee Share Posted September 27, 2010 According to Nvidia they say the maximum power that the GTX480 can use is 250w. http://www.nvidia.com/object/product_geforce_gtx_480_us.html Click specifications and scroll down to "Maximum Graphics Card Power (W)." 42 Amps would be the recommendation for an entire system running with one of the cards. 42A x 12v = 504 watts.
