Recently my PC started rebooting under load (maxed out graphics in games it is supposed to be able to handle). No BSOD or anything just blacks out and boots back up. Anyone have any idea what might be causing this? I've been monitoring temperatures and I don't see anything wrong.

My PSU is a Corsair VX750M
Intel Core i7 4770K @ 3.50Ghz
16 GB Dual Channel DDR3
Motherboard Gigabyte Z87ZN-WIFI
NVIDIA GeForce GTX 780 3GB
2 TB Seagate ST 2000DM001-1CH164 (SATA)
250 GB Samsung SSD 840 EVO

Voltages:
CPU CORE 0.876 V
MEMORY CONTROLLER 2.016 V
+3.3V 2.028 V
+5V 3.407 V
+12V 0.672 V (This is bad isn't it?)
-12V -7.008 V
-5V -6.144 V
+5V HIGH THRESHOLD 2.822 V
CMOS BATTERY 1.608 V

Thanks for your time!
 
Solution
Corsair doesnt make a VX750M. Did you mean CX750m? Those voltage readings are completely wrong system wouldn't even turn on with those voltages.
