Hi,
Last week I purchased a new Corsair TX650W power supply unit for my PC. After taking it out the box, everything looked fine. I took out my old PSU from my case and connected up the Corsair. I did everything the manual tells you to (although in fairness I didn't need to as installing a psu is quite a simple affair). I booted up as normal and my machine seemed to be running smoothly for about an hour. Then suddenly Vista crashed and I heard the hard drives coming to a halt. The fan on my graphics card also stopped. When I rebooted after that I got a Hardware Monitor Error during the POST, asking me to check voltages in the BIOS. The 12v reading was abnormally low. It was fluctuating between 9.40v up to a maximum of 11.07v. Also the reading was shown in red in the BIOS, which indicates there is a problem.
Is this a simple case of a faulty PSU? Or could there be any other causes at play here that are worth considering? Basically it's outputting some power on the 12v rail, but not enough to allow stable functioning of my PC. Also when I put my old PSU back in, everything works again and I get a stable 12.05v reading in the BIOS.
Right now I'm only about 70% sure the new PSU is faulty. I mean if it was completely busted it wouldn't output any power at all, right? I would assume so anyway. Also the site from which I purchased the PSU has this policy where, if you ship an item back to them as defective and they decide it's not defective, they charge £15 + vat and other charges which they do not specify. Then they ship it back to you.
Any suggestions on what to do guys?
