Anaksanamune Posted December 13, 2012 Share Posted December 13, 2012 Hi all. Couple of weeks ago my PC just rebooted, no BSOD, was just as if someone pulled the plug and pushed in back in. It has done this a couple of times since, and I had not discovered the reason. Today I press the power button.. I get the fans spin up for maybe 3 seconds then it goes dead, Self reboots and does it again, and again and again... I suspect a power issue, and try to push all the cables in more firmly (although none of them move and they all deem correctly in place). I reboot and manage to get into BIOS to check RAM / CPU settings etc (all correct), and as a matter of chance I look at the hardware monitor. In RED it reports: 12V line: 14.160 5V line: 6.056 3.3V line: 2.832 Now I have been told that the only good way to test is with a multimeter...but this seems excessive. Is it likely to be the cause of my problems? and is it dangerous of my system to be running with these values? Does the PSU have a self test and could this rebooting be the result of a POST failure?

peanutz94 Posted December 13, 2012 Share Posted December 13, 2012 oes the PSU have a self test and could this rebooting be the result of a POST failure? No it does not, but you can run the paperclip test found in the sticks on the main PSU forum page and then check the voltages from the molex and SATA cables. However, I would first try reseating the 24 pin connector on the MB and then check your voltages in the BIOS again. If they are the same, I would have the PSU RMA'd You by any chance are not using a 24 pin extension cable with your PSU are you? I have seen cases where the extension cables have gone bad causing those readings like that. Link to comment Share on other sites More sharing options...

Anaksanamune Posted December 14, 2012 Author Share Posted December 14, 2012 Sent in an RMA today. When returning a PSU does anyone know, should I send back the modular cables etc as well or just the PSU? Also if I send it back in the original packaging, with it be returned in original packaging? Sounds a bit weird but I don't like loosing the boxes. Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted December 14, 2012 Corsair Employee Share Posted December 14, 2012 Yes please include all of the cables as we will send a new unit with new cables. Link to comment Share on other sites More sharing options...
Anaksanamune Posted January 17, 2013 Author Share Posted January 17, 2013 Okay...so...I changed my mind on the RMA based on peanutz post seeing I use a 24pin extender. I wanted to be 100% sure. UP to today everything was working fine again with no problems, but today I hit voltage spikes. Only a couple of days before I had the case open...suspicious. Anyway I discovered wiggling where the extender joins the main cable can cause the voltage to seemingly fluctuate, and I guess closing the case panel can pin the connector slightly. Running perfectly fine now with the case panel off, but I can't leave it off forever...so...any suggestions? Link to comment Share on other sites More sharing options...
peanutz94 Posted January 17, 2013 Share Posted January 17, 2013 It may be best to replace your extension. I can't say for sure that is going to be the cure all, but it's very possible. Pull your extension off and check both ends for any burnt or discolored pins. Link to comment Share on other sites More sharing options...
