GTS 450 Issue, Power Supply bad? Tags: Graphics Cards Power Supplies Computer Graphics Product Last response: December 8, 2011 6:00 PM in Graphics & Displays Share zoorexult December 8, 2011 5:25:37 PM I just built a new computer. Gigabyte GA-880GM-DH2 motherboard AMD Phenom II 1055t 6 core. 8 GB Corsair Vengance. Seagate Baracude 750 GB sata HD. Above is all the new stuff. I had a 550w Power supply laying around, Mad Dog 550WPS. I figured its 550W PS and I should be okay, however I think this is the issue. Sometimes Computer will boot with card in sometimes not. I tried to Run passmark burn in test and I lose video immediately. Same test works good with my old 7600GS card in. The GTS 450 runs flawlessly in my old AMD 5000+ system still. Even ran passmark burn in test on that one and it works good. What I have concluded is that the 550W mad dog PSU is a not cutting it, and I need to get a new PSU from a proven MFG. Suggestions on good 600-750w PSU that I can get for under $100. Thanks.
