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. | Report abuse the elve September 5, 2011 11:29:38 AM thanks, Arthurh For you help , i ll try to change PSU GREETINGS | Report abuse Ask the community Publish Tom's Hardware>Forum>CPUs>AMD phenom II X2 555 unlocking !! bottlenecking problem?> Related ressources: ForumAMD Phenom II X2 555 unlocking core problems ForumProblems in unlocking amd phenom ii x2 black edition 555 ForumAmd II x2 555 BE Core Unlocking Questions/Problems ForumAMD Phenom II X2 555 BE Unlock Cpu Core ForumUnlocking Phenom II x2 555 BE?
