Computer restarts however only when playing games

[ianleezy]

Hi, recently for some reason, my computer keeps restarting whenever I load my games (overwatch,dota, PUBG) . It does not restart when I'm using windows. Any idea what could it be? I've done my research and most people tends to think that it's the PSU problem however I believe my PSU has enough power to supply my rigg. I'm not a computer expert anyway hahaa so any help anyone T_T

I'm using a RS-700-ACAB-B1 for my PSU i belive it's a cooler master B700 V 2

Your PSU has plenty of power (a 350W PSU would be enough), but that doesn't mean that it isn't causing the issue. It could also be the GPU.

Hmm sounds strange. If by any chance you get your hands on another psu I suggest u check to see whether the problem persists. It also be a windows issue where you can reinstall Windows and see whether it has solved the problem . I also suggest you update your motherboard bios to the latest version . But the worst case scenario is that there might be a fault in gpu as GhislainG thinks. But I hope you find the solution . Good luck to you 🙂

Edit : Before you check out another power supply I would suggest a 450w or 500w power supply from a popular brand such as coolermaster , Evga , Corsair , Antech , NZXT , Seasonic or any other trusted brand . Your power supply is actually low compared to people who would have a similar rig like yours so better stick to a 450watt or 500watt power supply to run your rig at a stable pace .

Hard restarts/reboot during gaming...

PSU is always a prime suspect...when a lower wattage rating, even more so...

Good luck

Hi,
I have the exact same PSU (RS-700-ACAB-B1), which is 700W, combined with a GTX980 GPU.
This combination runned fine for me more than a year, but recently I started to have the same issues: PC restarts sporadic. And the freaquency of restarts increases. Now when I start a GPU benchmark the PC restarts immidiately (so easy reproducable)
When I use my internal GPU (Intel 530) than all works fine, also the bench programs.
Therefore I still doubt if it is PSU or GPU

Your GTX 980 draws more power than the OP's GTX 550, but it shouldn't draw more than 15 amps on the +12V rail; unless it's defective, that shouldn't be an issue for a PSU rated at 54 amps on that rail.

You should test with another PSU to determine if it's the PSU or the GPU; a quality 500W PSU is plenty to stress test the GPU.
