Computer Shutting Down Instantly While Gaming -- Help plz

AnonymousDinosaur · Mar 31, 2016

So recently my computer has been shutting down and restarting while playing games. It seems to do this randomly, some days I can play for hours on end without it shutting down. Recently these shutdowns have become more frequent. The shutdowns have happened while playing these games: Ark, and Arma 2. I looked into this problem a bit more and my first guess would be the PSU. Using HW Monitor ive found that while playing Ark the +12v drops to as low as 11.616. Should I replace the PSU?? I checked the BIOS and it idles at about 11.938v And no I'm not overheating all temps below 70. Drivers are updated and computer hardware is not dusty lol.

My Specs:
EVGA SuperNOVA NEX750B PSU ------About A year and half old
i7 4790k
R9 280x Sapphire Toxic
12gb ddr3 ram
Samsung SSD
ASROCK H97M Pro4 Mobo
Win7 64bit

The NEX 750B is an interesting little booger because there has never been a single review of an NEX B power supply. There have been numerous reviews of NEX G units, but not NEX B. The NEX G units were poor quality units, so it is the general consensus that the NEX B is also poor quality.

I would replace your power supply with a higher quality unit if you want these freezes to stop. If you have a budget, I can recommend one.

So you seem like the appropiate person to ask this question, is 11.6v under load not okay for my specs? or?

turkey3_scratch · Mar 31, 2016

11.6V is well within the ATX specification which says the 12V rail must be between 11.4V and 12.6V. The 5V rail must be between 4.75V and 5.25V. And the 3.3V rail between 3.14V and 3.47V (3.3V mainly is RAM these days).

But as I said, software is innacurate. I would not be surprised if the actual voltage is 0.2V off or more.
