New gaming rig. Not sure if it is a faulty power supply.

[Scorpov]

Specs:
Intel i5 4690k
16GB DDR3 RAM
Asus Z97-Pro gamer
Asus GTX980 Rog Strix
Xigmatek talon black vector 80plus 750w

This build is month old and it works fine until I start a game. Doesn't matter if it is a GPU intensive game or not, the pc restarts everytime after 15-20 minutes (except League of Legends and Dota 2 they work just fine). The bios screen comes up with: "power supply surges detected during the previous power on. Asus anti-surge was triggered to protect system from unstable power supply".

So I disabled asus anti-surge and updated bios but the same thing happened. I gave the pc to service, they tested everything and even played 3-4 games for 30 minutes each, pc worked just fine. Now I have no idea what do to and no idea what might be the problem. Maybe it's the bad wiring in the house? Do I need a surge protector or something like that? Or should I just buy a new psu? I am newbie at these things and I'd really appreciate the help.

Id suspect the wiring in your house .

Take it to a friends place and try again

Thanks for the reply. But I never had this problem with my old pc. The thing im thinking about is if I get a surge protector would it be useful?

Not if the voltage is dropping in your house

It could be caused by A faulty VRM on your motherboard, it has 12 power phases so it should prove better if you are overclocking the CPU mainly and the GPU. Are you overclocking? If so, then it could be the quality of the PSU you are using does it just meet 80 plus standards? Try going with a 80 Plus gold standard at least, PSU are underestimated in the importance to a computer. The surge protector extension may help, but my money is on your PSU.

However before thinking about that last comment, try a different power source such as another house, just in case

The thing I don't get is if it's the faulty PSU shouldn't I be getting more problems? This only happens in certain games doesn't matter if it's GPU intensive or not, same thing happens in Battlefield 2 or 4. But I guess I'll just buy another PSU and see how it goes. Thanks for the reply.

You are assuming what the word 'surge' means. A surge can be a high voltage, a low current, a low voltage, a spike, or a high current. All are completely different. Why assume the word 'surge' is solved by a surge protector - which is for something completely different?

That surge message says nothing about hardware damage or protecting hardware. It exists so that future unsaved data is not lost. And so that you may fix a hardware defect before it gets worse.

Normal is for a defective PSU to boot and run a computer. That defect can only be identified by tasks that return numbers. That means a meter, some requested instructions and minutes of labor. To identify which of many power system components is defective. A PSU is only one system component. Only then can the fewer who really know this stuff say what is defective or functional.

Bad wiring house is a classic example of wild speculation. Never solve problems that way. If wiring is defective, then connect an incandescent light bulb to the same receptacle. Does a bulb dim to less than 40% intensity? If not, the computer sees perfectly ideal power.

Is a bulb dimming or brightening when other appliances power cycle? Then defective wiring exists; in rare cases is due to a major human safety threat. But even that is perfectly good power for any properly constructed computer.

Never try to first fix a problem. Always do what is necessary to first identify the defect. To obtain help from the fewer who actually know this stuff, well, that means the informed first recommended actions that result in numbers. No numbers means wild speculation or junk science reasoning. Provided was how to get a useful answer.
