PC randomly powers off after overclock

[mxknight77]

First I'd like to mention I've read around the forums about similar issues, but I didn't find the exact same problem or a solution to it. I've checked my power settings in windows 10 and my pc should never shut off. Secondly I have my i5 3570k overclocked to 4.7 ghz and my ddr 1600 ram overclocked to 1866 with the timings slacked a little bit. I've ran memtest and I've received no errors. I've also ran prime95 for 6 hours straight and my computer never crashed. CPU temps went up to 88C at the highest but stayed at 80 on average. It just seems to randomly shut down whenever I do no use it. Any thoughts on the matter? I also have a 750 watt power supply with a non overclocked GTX 750 ti so I know for a fact that I shouldn't be having power issues.

Don't Overclock It might have better performance. In the long run , it degrades the time / life span of the chip . It also voids warranty

I would say the you either need to try dialing your overclock down or test the PSU. What are your system voltages?

1.295 vcore
1.5 vram
Level 1 LLC
All the other voltages are set to auto

What are the 12v+, 5.0, and 3.3 voltages?

Not sure if you're asking for this.
+5V@24A
+3.3V@24A
+12V@62.4A

This is the PSU

Those are the rated voltages, I'm looking for the actual voltages. Download and run Speccy, it should give you these voltages.

i just want to see if anything is amiss with the PSU. More than likely you just need to drop down to 4.5/4.6 on your overclock and see if your stability returns.

If the overclock is unstable it should bluescreen, this is why I believe the PSU is struggling to power your system with the extra requirement from the overclock. Which brand/model is the power supply?

Sorry, I don't see those.
Here's an image showing you the voltages of some things I could find.

I have a strong feeling lowering it to 4.6 or 4.5 will fix the issue. I keep thinking just because it's fine on a stress test it's stable. Still not use to my PC just randomly powering off instead of a BSOD or freeze.

Thanks for the help I'll post if my system stays on through the night at 4.5 ghz or not.

What makes me suspect it's the overclock is that your temperatures are rather high. Try lowering the overclock and see if the problem goes away.

It's a 750w EVGA Supernova 2. The only other thing I can see being heavy on the power is the GPU. Mine only uses 60 watts of TDP so I should be good in that aspect.

4.6 ghz still had the PC randomly shutting down.
4.5 ghz did the trick. Kind of a bummer tho because I feel like the cpu is capable of more. It only gets to 68 C worst case scenario after 6-8 hours of P95. I also only need the voltages at 1.21 to run it at 4.5. Thanks bad actor.

Your welcome. Don't feel bad though, 4.5 is still very respectable.
