Computer cutting out when gaming.

[deskboard]

When I am playing a game (a mid to high graphics game) after about 10 min on average of gaming my whole PC looses power, just like that, no warning just like the power was cut to the PC. It happened with the first game I tested even "Metro Last Light" and happens with "Bioshock Infinite" and "Darkness 2" and even some less intense games and I haven’t even them turned the games up to max settings.
Initially I taught it might be the processor overheating and it was cutting out as a safety caution but I have since bought a Corsair H100 liquid cooling and installed it, I installed it perfectly and the processor is running in the teens and twenties degree Celsius with the liquid cooling compared to in the thirties degree Celsius with the stock fan. I then tried gaming again with the "Darkness 2" and after 20 min of game play I lost power again which was very disheartening but at least I know it’s not a processor cooling issue. I also tested "Bioshock Infinite" and another game and it also lost power.
I think it could be the graphics card or power supply problem. Although i tested a game while monitoring the GPU and the PC is cutting out when its only in the sixties (deg C) so i dont think its a GPU cooling issue anyway.
I feel like i have tried everything and need help. Feel free to ask me anything and thank you in advance.

You should try to find the problem before buying things in an attempt to fix it. A few possibilities:

Overheating: Keep a monitoring solution up while playing, preferably on another monitor, or play windowed in such a way that you can see your temps. Specifically, monitor CPU temperature and GPU temperature. I see you checked GPU temperature, and 60C is perfectly fine, but check the CPU as well.

Power Overload: It's possible your hardware is pulling too much power, even though the hardware you've specified here should be fine. Use a tool like a "Kill-a-watt" to ensure your draw isn't close to 750W.

OC Instability: If you have any overclocked settings, it's possible you have instability, either with the CPU or RAM. Normally you'd expect a BSOD, but if you have BSOD disabled for some reason, it would just restart. Make sure you run stress tests on the CPU, GPU, and RAM separately to verify one of these by themselves aren't the issue.

Other issues: If using a power strip, trying plugging your computer directly into the wall. Is it only the computer losing power, and not the monitors?

The Akasa "Venom" series is made by Andyson, which enjoys a reputation for producing low-quality units. I am assuming therefor that it is NOT the AK-PSS075FGM, which is actually 80+ Bronze. Most likely it is the PSU that is overheating and shutting down.
If all of the fans in your case are exhausts, the PSU may be unable to pull air through itself for cooling, unless you have it mounted fan-down so it can pull its own air from beneath your case.

I had a very similar problem with my computer.

I even started a thread about it: http://www.tomshardware.co.uk/answers/id-1640233/computer-restarts-randomly-bioshock-infinite.html

The thing that worked for me, is formatting the hard drive the game was installed onto (in my case a separate hard drive from my C drive, which made the whole process infinitely easier) and redownloading/reinstalling the game from steam/dvd. I didn't do the quick format, that only takes a few seconds. I did the full format which takes hours.

Others said that defragging the hard drive (or in your case trimming the ssd) might work. It didn't in my case.

Cheers,

Which software would you recommend for monitoring temps etc. while gaming? CPU temps are low too when gaming. IS "kill a watt" a physical device or a software monitoring tool?
I have nothing overclocked. Would you recommend i try these stress tests on this link? http://www.pcworld.com/article/2028882/keep-it-stable-stupid-how-to-stress-test-your-pc-hardware.html
The PC is directly plugged into the wall and it is the only thing that cuts out.

I have both intake and exaust set up and PSU fan is pulling air from underneath

 

[William Eddins]

I usually use HWMonitor for monitoring CPU: http://www.cpuid.com/softwares/hwmonitor.html

And yes, Kill-a-watt is a piece of hardware you plug in between your computer and the wall: http://www.p3international.com/products/p4400.html

And here's a guide for disabling automatic restart (enabling BSOD) in Windows, incase you're just "hiding" the error: http://pcsupport.about.com/od/windows7/ht/automatic-restart-windows-7.htm

I am saying your problem is the PSU.
