 Thresholds for heat are usually found in the BIOS setup of the
computer. But, most systems will emit a Beep when the temps
exceed the trigger values. That's why my first inclination was a
problem with voltages, which would cause an abrupt shut down
like you described without any forewarning.

Let's see, Power (Watts) is (Current Times Resistance (Squared))
Sorry for that, just trying to remember my Engineering schooling.

Really nothing to do except replace the power supply itself. Not
complicated, but requires threading cables and some work inside
the cabinet. A 400 Watt supply will cost you ~$50.00. But I
would still install a monitor app and check it's log after you stress
or use your apps that cause the shut off before upgrading the PS.
