I have a Asus P8Z68-vLX motherboard, i5 2400 2nd gen sandy bridge proc, 8GB corsair ram, 600W psu system. It was built in Oct of 2011. In the last 6 months or so, my system has just suddenly power reset itself. There are no events written into the event logs prior to the power reset. I thought maybe it was a problem with my cpu cooler (corsair H60), but it is working correctly. I did remove and replace the thermal paste on my CPU. I also replaced my video card (replaced geforce 440 gtx with a geforce 760 gtx. In the last few months the problem has gotten worse and since I added the video card you can count on the shutdown occurring at least once or twice a day, usually when gaming but the system can be idle when the power reset happens. I checked all the cables for faulty or lose cabling. CPU temp staying between 80 and 100F, MB between 80 and 96F. One thing I am not sure about is the vcore voltage which bounces between .9 and 1.2V. Any ideas on what is causing this?
i would try to test that psu in another system voltage fluctuation is not good use this on the sensor part to read temp and voltage on your system and report back the result http://www.hwinfo.com/download.php
Scout - Does it matter what I use to test the psu? I dont have a different system to switch it to. Brarboy - Its a HEC XPOWER600 ATX Power Supply - 600W (Model#: XPOWER600)
i dont see any 80+ certification on your psu. I would recommend testing your system on atleast 550watts psu which mentions that its 80+bronze certified atleast. You may not be giving adequate amount of power to your whole which it demands, so such problem may appear
