pc crash no BSOD

[Volanaro]

hi guys so im current having an issue, where my pc decides to crash, (restart) without bsod, i have a feeling its the psu but not %100 sure

6700k, @4.5 iv tried stock, and same issue
16gb 3200mhz ram
1080ti (Stock oc)
750W psu


the only thing i can see in the event viewer is Kernel power (41)
i did cause it to crash again, with a  ADIA 64 test with Everything  but the Hard drives under test, but, when i tried to test it again, it was fine, 

so am i right in thinking its the psu thats on its way out?

What make and model is the power supply?? How old is the power supply?? 

 

Event ID 41s are generally unexpected power loss/shut downs without notice and generally do not give any more information than that. Make sure CPU and especially GPU temperatures (1080 Ti is getting old there and may need the new thermal paste as it only last a couple years) are not overheating.

It's a corsair and a 6+ years, the 6700k is delid with new paste and the 1080ti both are on water,  so temps are fine on been watching them, I did have a 850w corsair rm that would power off like this but it was only maybe a year old when it started? 

 

Currently doing a memtest

Also to add the only new thing if added is a razer Huntsman V2 analog, maybe all laser's and the leds? But I calculated my system power under load to only use around 420w ish. So that leaves around 300w  for hds, pumps, leds
