I had a reboot during a stability/stress test.
Specs:
CPU : FX-6300 @ 4.0 Ghz
MB : Gigabyte GA-78LMT-USB3
GPU : GTX 960 Asus Strix
PSU : Cooler Master Elite V2 550w
RAM : Adata DDR3 1600 mhz
Storage : 3 500gb HDD and 1 120 GB Kingston SSD
2 120mm LED Case fans running off case SPDIF in the front ( pulling air in)
2 cougar pwm 120mm in top (exhausting)
Cooling : Antec 650 H2O Kuhler (exhausting)
Case is the iBuyPower Arc series

Not sure how much Wattage my system is using but i feel like its a weak psu for everything i have in it, causing the reboot. Because my thermal margin was fine about 37.8 C and all temps monitored were fine.

Any idea why it would shut off during a stress test? I used AMD Overdrive stability test when it restarted. When i had my 6300 at 4.1 ghz i used Prime 95 for a bout 30 minutes no problem, i felt like it was a bit hot so I reduced the OC to 4.0 and stress tested again and it shut off. Maybe overdrive is the problem? Lol

Also rate my system 1-10 :)

No, not really. Dying Light is really intense puts my CPU up pretty high on the usage, and even the GPU but it doesn't reboot.

Overclocking it could be the problem. I would return it all back to stock settings, and then re-run the stress test. It could be getting hot if you have it clocked too high then restarting on it's own because of high temps. It COULD be you PSU. I don't think your PSU is all that great, and under a heavy load it might not be providing proper power to all the components. But I would focus on returning your CPU to stock settings and re-running a stress test first, and see how it acts.

Yeah thats probably not the problem. I reworked the overclock to 4.0 ghz then boosted the BUS to 207. ended at 4140 mhz purely stable and no more reboots.
