Completely Random Shutdowns

For the past three weeks, my computer has been randomly shutting down and rebooting. After post, I get a screen telling me there was a power surge, but nothing else in the house is affected.
The shutdowns seem to occur more often while gaming, or other heavy use. My psu is a Thermaltake Smart M 750W, and my cpu is an i7-3770K, which rarely gets hotter than 55°C. There really isn't any warning of it. Nothing slows down, the computer doesn't get louder; it works completely fine then suddenly turns off. Any help is appreciated.
