Complete loss of power

[Ghost Ookami]

Hey guys and gals, I'm coming here for a friend. He's currently having a problem that I am unable to help him further.

The computer he uses (tower not laptop) seems to lose power under any load. It started about a week ago without any hardware or software changes other than maybe a gpu driver. Since then he is barely able to open up any tabs in when browsing the internet before it will completely lose power without warning. While idling it does ok, but as soon as he opens more than a few tabs it will lose power.

I originally thought it might be the power supply due to it being quite old but when he got a new one that didn't change anything. Already tried different plugs as well to rule out a faulty power strip. Looking online had some info about maybe a corrupt OS or needing to update BIOS, I'm a little hesitant to have him update his BIOS in case it fails mid update.

I'm quite at a loss right now, I've not experienced anything like this before which is why I'm turning to you guys.

This is the new PSU
https://www.newegg.com/Product/Product.aspx?Item=9SIA1K645T6904
He runs a AMD FX6300 CPU and the current temp is sitting around 49C idling.
GTX 960 GPU
16gig of RAM 2x8g sticks
HDD
W10 x64

Trying to load a game just now to put it under some pressure the cpu jumped up to 65C and lost power.

I would think it sounds like a heat problem but nothing gets to crazy that would normally cause an issue.
Update, after putting the pc under load, the gpu, cpu and mb were not overheating at the time to power loss.

Sounds to me like a CPU related issue, If possible try a different CPU or motherboard as it could be the motherboard as well or both.
