Hello everyone!

As the title points out, around 2 months ago, I built a new system and, as of late, I've been having problems with random reboots. I've read many threads and tried everything these suggested: stressed test the GPU, CPU, diagnosed my RAM with memtest, used the windows driver verifier function, fresh windows reinstall, checked for hard drive errors, and to no result, the reboots keep happening. I have even disabled the automatic restart in order to let the system have BSOD, but nothing.
I was hoping you could lend me a hand with this, since it's been driving me crazy for the last few weeks and I have no idea what to think. I am leaning towards thinking that I may have a faulty PSU, but I can't really ascertain since I don't have the proper equipment to diagnose it.
Here I leave you my computer specs:

Motherboard: Intel Core i3/i5/i7 ASROCK B85M-HDS SK1150 DDR3 PCX3.0 MATX HDMI USB3.0
Processor: INTEL CORE I5 4590 3.3 GHZ SK1150 6MB 84W HASWELL
CPU FAN: DEEPCOOL GAMMAX 200
RAM: x1 8GB DDR3 1600 KINGSTON HYPERX FURY BLACK CL10
GPU: 2GB MSI GTX 750 TI OC PCX3.0 DDR5 HDMI TWIN FROZR GAMING
HDD: 1TB SEAGATE SATA3 7200 64MB BARRACUDA
PSU: This component is nowhere to be found for some reason. It is a 800W INNOBO PFC PSU (picture with the specs of the PSU http://imgur.com/PtKnl7I)
SYSTEM: WINDOWS 8.1

I hope you can help and thanks in advance!

Out of curiosity, is it because the brand is unknown therefore unreliable or is there something wrong with the voltages? Anyway, thanks for the quick answer! I will try to get a new one as soon as I can and see what happens : )
