I just built my first PC and I have been getting random shutdowns. The shutdowns usually occur after the PC is on awhile. I built this PC about 2 weeks ago and I started to notice the problem about a week ago.

PC specs:
Maximus VII Hero
Gigabyte GTX 970
i7 4790K
8GB hyper x ram

I also have 6 fans, a corsair h105 cpu cooler, 1 ssd, and 1 hdd all of this is running on a EVGA SuperNOVA 750w power supply. I think the 750w is enough but I could be wrong so I don't know if I don't have enough power which could be causing the shut downs. One last thing I noticed is that my power supply gets a bit warm when these shutdowns occur. If anyone has any suggestions on what could be causing this or how to fix it would be very helpful.

The thing is every time it shuts down i am not looking at the screen. It always happens when i am not looking. But my average temps are around 41°c. I do feel more heat coming out from it when it does restart.

it's an instant power cut.
 


Hmm I wonder if there is some manufacturing fault in the PSU that would cause this.
