I have a question is this power supply enough to power a pny nvidia 580 gtx http://www.thermaltakeusa.com/Product.aspx?C=1245&ID=1830 System has the following hardware: CPU: I7 960 Video: PNY Nvidia 580 GTX Memory: 12 gigs triple channel Hard drives: 2 SSD's Intel 120 gig Sound: X-Fi Titanium Nic: Killer Nic DVD Burner The reason I ask is because I ran into an issue about a year ago with the original configuration which was a 975w psu with a ATI 5970, I changed them out because I was having issues with video corruption and thought it was the power supply or the video card.. I also reformatted the PC at the time when I added the new parts. What is strange is after I bought the new parts PSU, Video card and SSD drives everything worked great for about a month and now all of a sudden I am having the issue again so I ran a memory check last night and it ran ok no errors so now I am at a loss as to what would cause this issue... I now have 2 video cards one ati 5970 and a nvidia 580 gtx both have the problem and I have 2 PSU's a 975w and a 850w both have this issue cause video corruption.. I have ran thermal checks on the card to make sure there not over heating and they never break 59 - 60 on the temps same with CPU it never gets hot.. Any advice would be greatly appreciated.
