Hi everyone,
my specs are:
i7-10700K
32 GB RAM
RTX 3080
AURUS 850W GOLD PSU

Recently I get these random sudden shutdowns exactly when i start/play a bit in some demanding games such as Warzone, GTA V, World of tanks and so on.
In the event viewer i can only see Critical unknown reason for shutdown so I checked the cpu utilization and temps while recreating the shutdowning events and it seems to happen every time the cpu stays few seconds on 100% utilization.
cpu temps don't go over 65 degrees C also gpu temps are low so its not a thermal problem and I don't think the 100% cpu utilization is a problem.
I can only think of the PSU as a problem but it only started happening few months ago and i have this pc for almost 2 years..any thoughts??

any help would be much appreciated thank you!
