In events where we have to troubleshoot a system that isn't being responsive or disobedient, it's always a good thing to go through the affected system's specs. That being said, if you are certain that the temperatures are all alright and there is no overheating issues then the issue can be pinned down to your PSU. Though as a small test try getting into BIOS and try staying there until you see the system shut off which will indicate that the PSU can't handle the load and is shutting off to safeguard your system from receiving damage.

Worst case scenario, the system is shutting off due to a failing component in your system.
