Your 555 draws 80W stock + all the other components in your PC. IMO you need a larger power supply. I would go for a 750W, LINK, as long as you stick with only 1 GPU. m 0 l the elve September 5, 2011 11:29:38 AM thanks, Arthurh For you help , i ll try to change PSU GREETINGS m 0 l Can't find your answer ?
