Could be your none Quality PSU trying to kill the card! The card can run up to 105°C. It is the PSU that is shutting down the computer. Just a matter of time that it will kill other components!
There are two 600watt units from Logisys on newegg at the moment both SLI ready but each has only 25amps for the +12 volt rail. That is a rating for a sub 400watt PSU!
