Going by your temperature info the machine bombs due to a temperature spike when all cores are working hard. Nothing wrong with PSU.
Agree, the PSU has been exonerated long ago.
Temperature spike? Is there such a thing? It would possibly explain the situation. The lm-sensors output (that's all I have for now) will occasionally jump a degree up and down, but I'm taking that to be a rounding thing. Is it really possible for the CPU temperature to jump e.g. 5 or 10 degrees for a second and then settle back down again?
I don't know by how many degrees, but a CPU that is fully utilizing all its circuitry will be hotter that one that is not. And yes the spike can be pretty short, but I doubt just a second or two. ie. You do a whole bunch of floating point for a short period, then you are causing more of the CPU to be used, so more heat. When the floating point work is done, that part of the cpu quits producing heat and the heatsink will start cooling the cpu back down. The cpu has lots of subsystems that only get used at certain times.
