Pc reboots while playing games (NOT overheating)

[KyouBlack]

Hello, I've built a pc recently and I've been playing some graphic intensive games. Lately my pc has been rebooting while playing these games and now I can't even play 5minutes straight without that happening. I've checked the temperatures and they're all fine. I also did stress tests to everything and it fails immediately in the graphics. Can anyone help me with my problem?

Here are my specs:

PCU: Intel Core I5 4460 3.2GHz (3.4GHz Turbo) 6MB BOX
RAM: Corsair Vengeance 2x4096MB (8GB) DDR3 1600Mhz CAS9 1.5V
GPU: Asus GTX760-DC2OC 2GB GDDR5 PCI-E
Motherboard: ASRock Fatal1ty B85 Killer Intel B85 SK1150
HDD: Western Digital Caviar Blue 1TB 64MB SATAIII (6GB/s) - EZEX
PSU: Nox Urano VX 750w

A no name PSU can sometimes be a problem. I had a thermaltake power supply before and it keeps making the computer restart due to it being faulty. I replaced my PSU to a CX600 and it ran fine. Also when your computer restarts did you get a blue screen or did it just restarts randomly.

It's not BSOD, no screen appears. It just restarts

Then it must be the newest nvidia drivers causing the no BSOD Screen. Back down to an older nvidia driver to fix this

You don't always get a BSOD when something goes wrong. This is why I said to look in the logs.

Something is problematic in that PSU. It only costs EUR52, although Seasonic 750 Bronze Evo costs EUR119.
If you want to get a new PSU, that's the one: http://www.pccomponentes.com/seasonic_m12ii_evo_edition_750w_80_plus_bronce_modular.html
It's the 750W counterpart of the one you linked, although, you'd do fine with a 620W.

I didn't say that about your PSU. I said I've never heard of it which could be a bad sign. It might be fine.
I still think you should identify which component is causing the problem before jumping the gun.
Even the shittiest brands can put out a PSU that does fine. It's just a higher likely hood it will fail earlier or deliver 'dirty power' to your components.
The fact you seemingly have a no name PSU and your having trouble which is quite often associated with a faulty PSU it's just the most likely cause.

UPDATE: It now happened while browsing the internet, I didn't even need to launch a game.

Certainly sounds like the PSU could be the cause.
