If you're wondering the psu in question is an antec vp550p More about : 30a 12v rail gigabyte 7870 Best solution anort3 a c 255 U Graphics card December 25, 2012 12:57:57 AM The Antec VP 550 actually has multiple 12v rails capable of supplying 540 watts on the 12v rail alone making for 45 combined amps on the 12v rail. It's a very good power supply and would be fine even for a GTX 680 or HD 7970. Share timil December 25, 2012 1:17:21 AM Best answer selected by timil. m 0 l Can't find your answer ? Ask !
