The problem with PSU is that my choices here are very limited, either I can buy this brand or Cooler Master MasterWatt Lite 700W which has been made available the only couple of months ago.
and unfortunately, I don't have any spare part so that I can swap them. That's why I'm asking for help so that I can narrow it down to a specific part and then either buy a new one or send it back to for warranty/guarantee whichever applies.
By the way after 4 hours of prime 95 with small fft, nothing happened, but I had several interesting observations :
First of all here are the starting and ending entries for CPU temperature when I started the small fft :

The ambient temperature is the same, it seems small fft makes the cpu hotter!
I also noticed the vcore voltage being around 1.09v while at the moment where nothing is running, it fluctuates between these 3 numbers : 1.280 to 1.182 to 1.231

Could this be the cause?
I downloaded IntelBurnInTest, do you think it would be better to run some tests with it instead of prime95 and see the results (before starting OCCT tests)
