Is there adequate air flow in your cabinet? Seems like component are overheating and causing the system to reboot. What case and CPU cooler you using?

If there is no blue screen, just a power off, then I would say your power supply is the problem.
A decent 650W supply is plenty for this build, but the Corsair VS series are not good quality and yours could easily be faulty.
If you have a look at this list, VS series is tier 4:

Have a look for something from tier 1 or 2.
Some suggestions:
Antec HCG 620
Seasonic S12II 620
Seasonic S12G 650
EVGA Supernova G2 750

temps are all fine as far as i have checked.
Im using Cooler master hyper 212x evo.
Cpu doesnt get hotter than 65-75 C.

so do you recommend just buying a new good psu and replacing it ?

If the PSU is still under warranty you could try just replacing it for free, but if not then buy something better.
