PC Restarts when playing games HELP

[TungaM]

I refreshed my pc about a month ago with a 5600x and a new cooler nzxt kraken x63. a day ago When playing Beyond the wire it restarted my pc and did it on ark as well. I checked my thermals and they were normal, I even replicated the crash and did not see any large jumps in temp it stays in a good range under 70c. I used software to check my RAM and it was all good there no issues reported. It left me with 2 options: PSU or software related. I hunted down fixes for software and it didn't work and just decided to do a clean windows install to completely rule out any software issues and it seemed to work. Today around the same time boom it restarts again so it isn't software related. I assume it is the psu its a 750 watt evga 80+ gold semi modular and I got it six years ago. I think maybe with the age and the big jump in power consumption is causing it to fail. I also noticed a sound coming from my pc only when I put it under pressure it never made and I believe it is coming from the power supply but I am not too sure. Anyone care to input any other potential culprits?

usually this happens because of not enough wattage. you have enough. How long is the warranty on it? run chkdsk or something (idk how ul have to google it ;-;) and make sure its not a drive issue

I ran chkdsk on all my drives and no issue however my keyboard was being strange after I restarted and I read somewhere that external devices can cause this as well I will get my hands on a keyboard and see if things change in the meantime I do have a bios update and I will also attempt rollbacks on updates.
