Pc restarts after 5 minutes when playing a game.

Hi , When I'm trying to play Call of duty Aw or bf4 for example , after 5 minutes of play my pc restarts, I did prime95 blend test and nothing happened,but when I did occt psu test , the pc restart.
When I'm playing the temps are between 60 to 70
Specs :
I5-4690k
Gigabyte gtx770
Gigabyte z97x-sli
8gb of ram
PSU - HEC Cougar 550

Either temps or PSU. Given the pc restarts when doing a PSU test, I'd wager that's the problem. I've never heard of HEC, so I'd wager its a shoddy PSU that can't handle your PC's maximum load.

But 550w suppose to handle my system

It will but the PSU could be defective. Have you recently built the PC or added any components and are the temps CPU or GPU? What GPU temps are you getting in furmark? (Run the furmark 15min benchmark, if the temps exceed 90c shut it down)

Quickly skimmed two reviews (JonnyGuru and Overclockers and both had issues with sub par build quality)

There are a lot of crappy PSUs out there that claim they can deliver 550 Watts, but there is always a catch. 550 Watts could be the peak output that it can only sustain for a short period of time and the continuous rating is much lower. The PSU could be 550 Watts but only delivers half of that on the +12V rail where most of your power consumption is while the other half is split between +3.3V or +5V rails that hardly use any power on modern systems.

I've tried looking up your PSU but I can't say for sure what you have without an exact model. The HEC Cougar PSUs apparently should offer the power they advertise. One possible problem you may be having is the models I've seen from my Google search have multiple +12V rails, and it's possible that you are overloading one of them by connecting both your CPU and both of your GPU connectors to the same rail. If you have alternate power connectors for your GPU, you may want to try them and see if that helps, assuming your PSU has multiple +12V rails, it will say so on the label attached to the side of the PSU.

You could also have a defective unit that simply craps out when it gets put under heavy load, in which case it may be time to RMA it.

I'm getting between 60-70 cpu tems while playing cod aw
and 40 gpu temps

Is this normal?

 

[mouse24]

I don't think those GPU temps are correct. Try using furmarks 15 minute benchmark and see what you get.

 

[sabag123]

When the gpu gets to 70 degrees while running funmark , my pc restarts.
funmark stress test it is.

 

[mouse24]

Yup sounds like its a power supply issue then, I'd RMA it if its a new build/psu. 70c is very safe for a GPU so it overheating shouldn't be the cause of the restarts.

 

[sabag123]

So it's not a gpu/cpu issue?

 

[mouse24]

So it's not a gpu/cpu issue?

I'd be surprised if it was. The temps are fine, the power supplies quality is suspect so its naturally what I would bet on. Added to that is the fact that it only reboots under high power usage (cpu doesn't really draw much power)

 

[sabag123]

And what about this ? http://i.imgur.com/R0pagnn.png is this normal?

What were you doing during this? If it was playing a game then yes its perfectly normal. If its sitting at the desktop, not so much, downloading GPU-z and screenshotting would give us more information.
