Computer randomly turning off after 10 minutes of playing games

I just built a new computer and out of no where it keeps turning off around 10 minutes after I'm playing a demanding game such as the Withcer 3 or Farcry 4. However I can play Dota 2, maxed out getting around 110+ FPS with no problem.


The PC just shuts down, no noises or anything just completely powers down and boots back up a few seconds after. It can't be to do with the temperatures as the max Temp from my CPU is around 60 and same with my GPU. The MOBO, HDD and SSD are also cool at around 20 - 30 (Celsius)

I've tried re installing GPU drivers, running stress tests to try reproduce the problem, checking Event viewer for anything (there's literally nothing helpful in there) and now I'm all out of ideas. My best guess is that it's my PSU but just wanted a second opinion before I go out and buy a power supply. Thanks!

  1. Which power supply do you have now?
    Brand and model please

    Bios of motherboard up to date? Which version?

    Did you replace an amd graphics card and didn't reinstall windows? Then use DDU uninstaller

    Boot with memtest86+

    Check hdd and ssd with manufacturer's tool
  2. PSU:

    How do I check the version? I ran @Bios and just updated it now.

    And no, it was a 660 before I had this 970 in. I did re install windows (upgraded to 10 as well to see if it would make a difference since there's a change between W7 and 10 drivers). I also used DDU before and nothing.

    I'll try memtest now

    There was a firmware update for my SSD (although I'm running the mentioned games off my HDD so that shouldn't make a difference I guess unless only games on the HDD are causing it to shut down maybe? I'll try moving a game over and seeing what happens)
  3. Everything was fine on the Memtest
  4. Best answer
    does this psu provide PCIe 8Pin connectors or do you use an adapter?

    my best guess would be the PSU too.

    get a quality psu from tier one or two with like 650W max.

  5. I'm using an Adapter. In the future if I wanted to SLI and get to 16GB of ram (perhaps a new processor) would 650 be enough? thanks in advance! :)
  6. If Memtest was fine and your temperatures are fine, then the next place to check is the power supply. To be perfectly direct, you have a junk power supply in there, not one I would even want running one GPU, let alone looking to SLI in the future. It's a low-end hec-made PSU and a "750 W" PSU that doesn't have the proper connectors for a GPU is a big, gigantic red flag.

    We can't be 100 percent sure that your PSU is causing this specific problem, but when trying to diagnose a problem that doesn't have an obvious cause, it's trickier when a junk PSU is in the mix.
  7. Yeah I've had a few issues with it in the past as well wanna chuck it out for good, was thinking about getting http://www.corsair.com/en-gb/rmi-series-rm750i-750-watt-80-plus-gold-certified-fully-modular-psu-uk

    That one. However I noticed on my MOBO that the CPU plug is only a 4 pin and I don't see any 4 pin plugs on that psu?
    Is it 1 8pin that splits into 2 4 pins or am I toast and will I have to update my motherboard as well?
  8. Alright, bought a new power supply (http://www.amazon.co.uk/dp/B00MFD3KZC/ref=pe_385721_37986871_TE_item_image) It'll come on Friday. I've switched out to my old GPU to make sure that if this piece of shit PSU damages anything my 970 will be okay.
    For anyone who's having a similar problem and reading this, I'll let you know if it worked out Friday evening GMT.

    It's labeled as the "4+4 CPU" connection. It can be used as a 4-pin connector or an 8-pin connector (with the other part just not used) depending on the motherboard.

    I'm very happy you made the decision to upgrade the power supply! You'll keep your parts much safer and healthier in the long run. I hope the new PSU resolves your issues.
  10. Sli is Not possible with your motherboard, just crossfire.
    If you wanna use sli in the future, you will have to get another motherboard and most likely another CPU as well, because the 1155 socket boards with sli are very rare and expensive, even used prices.

    Ah right okay, they're on my list of things to upgrade anyhow. Thanks for the information though :)
  12. A new power supply fixed the problem, if anyone else has a similar problem but is sceptical about splashing out on a new power supply feel free to message me, I'm more than happy to talk through exactly what my problem was and if it matches up to yours. Thanks again to the people who helped me <3

    Glad it worked out for you! We recommend these power supplies for good reasons, I'm happy you took the splash and it fixed the issue.
