PC keeps crashing during benchmark

[ahhdoom.nguyen]

Hello all,

My PC recently crashed multiple times during a gaming session of dead by daylight and gmod.

I tried my best from my current knowledge and web surfing to figure it out.

MSI Z370 Pro Gaming Mobo
2 x 8 DDR4 Ram
Nvidia GTX 1080 GPU
Intel I5 8600K CPU
Corsair H115i Pro AIO
Thermaltake 750W Gold 80 PSU
6 fans 80MM
SSD + HDD
Not overclocked.
BIOS up to date
Drivers up to date

I tore my PC apart and cleaned it up. Fresh install of W10 aswell.

I ran FurMark. GPU just fine.
Ran OCCT. CPU was fine.
Ran Windows Memory Diagnostic. RAM was fine.
Checked temps with speedfan. Looked okay as well.

BUT when I ran USERBENCHMARK it keeps crashing almost at the very end. I did this a few times checking the CPU and GPU temp and it looked fine. All fans are running smoothly.

I tried running both FurMark and OCCT and it obviously crashed too.

Ran chkdsk /f sfc /scannow as well. Those came up fine.

I want to say it is my PSU since everything else is so very new. My PSU is about ~5 years old now? But I'm not sure how I can test that either.
I'm quite stuck and would like some help if possible before I send it in to microcenter for a checkup.

Some other information is I had it hooked up to a monitor and a TV. Cause I play VR and some other party games. Not sure if this info would help. I took everything off and only left my KBM to do the testing.

What else can I do to resolve this?

well the best way to check your psu would be the paper clip method and a multi meter to check the 12v 5v and the 3.3v output.if you are not comfortable doing this i would suggest downloading and running hw monitor.you can check the voltages by running that.if you do want to dig deeper post back and i will try to find the link i was looking at.

thanks for the reply. I just downloaded the software and ran it. What should I be looking for in the voltage if I believe it might be the cause of it? What test should I run and what to look for during the test as well?
Currently what is being shown with no testing.

in the very first set of voltages when you open hw monitor you will see 12v 5v and 3.3v and a voltage value (val-min-max)on each.post back the results.

I do not see the 3.3v but there is a
12V Value: 12.192 Min: 12.096 Max: 12.192
5V Value 5.080 Min 5.080 Max: 5.120
3VCC Value: 3.360 Min 3.360 Max 3.360

ok,dont know how feasible this is but if you can run your benchmark tool have hw monitor running at the same time.its not gonna be easy but if you can keep an eye on the voltages while the benchmark is running it may give a clue.just a thought tho,what exactly does the pc do when it crashes?any error code,blue screen?
