Hello guys,
My computer started shutting down suddenly while gaming. It was restarting right after shutting down. At first it was only during gaming, but then started to happen while browsing.
It was rare at the beginning, but soon started to happen more often.
Temperatures were fine for both, CPU and GPU. No anomalies detected.
I tried lowering the power limit of my video card on Msi Afterburner, started with 60% (40% reduction). The problem was gone till I backed up the power limit to ~85%. So I realized that it was somehow related to energy (which led me to the PSU). I was testing on a Nvidia`s Benchmark: Heaven Benchmark. As soon I ran the test, the PC shut down, like immediately.
By now my PSU is under check-up on a local store. I will update here as soon as I get more news.
If anyone has had the same issue and solved it, please post here the procedure to help future researches.


Specs:
I5 - 4690K 3.5 ghz
RAM: 2x8gb dd3 2400 MHz Corsair
Mobo: Msi z97-g45
Video Card: evga gtx 970 sc 4gb gddr5
PSU: Thermaltake 650w
1 year and 10 months of use.

Sounds very much like a dying PSU. I'm sure we'll all be interested to know if that's where the problem really is, because if we're to tell people to buy a new PSU we want to be sure it's the right advice.

There, now I'll get notification if/when you update this :)
