That's also what I was thinking but itf the PSU were to trip, it would completely shut down the system instead of freezing would it not? Still not sure how its able to maintain 100% load for so long but only trip or freeze when the task is shut down after the task is complete. Also, no OC. Everything stock except the RAM to run at its rated speed. I forgot to include it, but even at stock settings for RAM running at 2133 Mhz, CPU running at 3.9 Ghz, and GPU running at 1700 Mhz, the PC still shuts off or freezes.
