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?

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 :)

I had a very similar problem about a month ago or so.

I ended up replacing my PSU for about 60$ and that ended up fixing my problems completely.
The computer can run games, youtube, and skype while staying at a moderate temperature.

I highly suggest picking up a new PSU and testing it out.
Most stores will allow you to return it within a few days if it doesn't work out.
