I recently built a computer and been playing a few games on ultra settings without issues. Well last night I bought Rust and was playing it and about 3 minutes in my computer rebooted. Booted the computer back up and tried playing Rust again....then it rebooted again. So got things going, turn the graphics settings down and the game ran fine. So being curious I download 3Dmark and ran a test...about 8 minutes in the computer rebooted. Could it be my power supply is not putting out enough juice? http://pcpartpicker.com/p/6BQyRB
