ipvelez Posted March 11, 2012 Share Posted March 11, 2012 Hello, I built a new PC using a CORSAIR Builder Series CX500 V2 500W power supply. For a couple of days it appeared everything was ok, but lately I have been experiencing random reboots. It may reboot when I am playing SC2, or reboot when I am just browsing the internet, or bsod after being unresponsive several seconds. After the reboot, it appears as if the hard drive does not exist. If if unplug and plug in again the power, and turn on the Pc, the hard disk is there again. Yet, when I enter to the BIOS, I see the voltages are: 10.20V in the 12V rail, 4.30V in the 5V rail and 3.36V in the 3.3V rail. I also used my digital voltmeter to measure voltage in the molex power connectors while the PC was running, and it says the same 10.20V and 4.30V voltages. So my question is: Are these voltages (10.20V & 4.30V) too low? Can these cause the random reboots, blue screens, and other strange things with the hard disk? Thank you very much for your help! -ipv Link to comment Share on other sites More sharing options...
Logiven Posted March 11, 2012 Share Posted March 11, 2012 I had to RMA my PSU for the same reason, 10.20v is too low... did you test the PSU alone ? or in other motherboard ? http://forum.corsair.com/forums/showthread.php?t=63991 Link to comment Share on other sites More sharing options...
peanutz94 Posted March 11, 2012 Share Posted March 11, 2012 If you can test the voltages with a multi-meter would be best and give you a definitive answer. If the reading are the same, then yes, RMA the PSu. RMA it even if you do not have access to a meter. Those voltages are too low. Link to comment Share on other sites More sharing options...
