Random shutdowns w/o bsod

[Le_Golden_Magikarp]

Ever since i built my computer I've been having problems with the computer shutting off randomly and I really can't pin down a reason or cause for it to be doing this. I've tried enabling and disabling XMP and gameboost in my bios, i've tried resetting the bios, i've even tried a new motherboard, but nothing I do seems to fix the problem. My specs are as follows 

i7 8700k

RTX 2070 super (founders)

MSI z390 gaming edge ac

16gb 3600mhz corsair vengeance

750 corsair cx750 psu

i'm also not overclocking my gpu or cpu currently.

since you've already replaced the Motherboard, i'm going to say it's a PSU problem

i was thinking it could be that, but that just seemed unlikely since it was such a big psu, especially for the build

Could be bad memory too. I would run MemTest.

Doesn't matter how many watts the PSU is if it is broked.

Big - yes. Faulty - who knows. But probably not.

 

Install Windows on spare drive and use only standard drivers without 3rd party tools (boosters etc) just for tests (second drive because I don't think that is system fault but who knows). And install monitoring software (MSI Afterburner will be fine). It may be even bad GPU so try to underclock your gpu using that tool.

ran memtest with no errors, so it probably is the PSU

Also, no matter if ram tests pass or not, try to use only single stick of ram.

this has happened across multiple gpus, i just upgraded to my 2070 but it was having the same issue when i was testing with a 750ti, and if anything it was worse. it was also having the issue with my 970

Have you done a clean install of Windows?

yeah, i've had 3 separate installs on this computer now and they've all acted the same

Oof. Different drives?

 

What's the power situation feeding your PSU?

[Le_Golden_Magikarp]

it's all been on the same drive, and right now i have it plugged directly to the wall, i had it on a powerstrip before but it was doing the same thing.

I highly doubt it is your issue but that drive may be worth looking into. 

 

Any chance of odd electrical issues going on behind the scenes?

none that i've noticed, even when my pc goes out everything else around my pc will stay on, like if i'm playing games on my switch it won't even skip a beat and just keep going, even when it was connected to the same power strip

Definitely do that. It will have a record of what caused the crash.

Yep, this answers your question. 

 

Kernal Power - 41

 

Your computer "lost power" unexpectedly.

 

Because of all your troubleshooting you have already done you are limited to your PSU or the power to the PSU.

should i contact corsair and be like "yo shit's busted" and probably just claim warranty?

If your PSU is still under warranty 100%. If you can get another PSU to test with that helps your case.

Kernel Power 41 error means nothing. It's just like "your computer shut down", but you already know that. PSU may be your problem, because you basically eliminate all others possibilities.
