PC restarts when gaming

[MarioBeTrippin]

I've had my PC since March and since then it has been restarting (completely rebooting) when i have been gaming. It first was occasional but now happens quite often and i can barely play anything. CPU temperatures have been between 40-45C and system temperature have been 50-55C when the restart happens. I have updated my driver and BIOs. Checked event viewer only the kernel power ID : 41 appears. I took advice to increase ventilation and swapped from the mini prodigy case to the cougar pioneer and to add the cpu cooler. That was a few weeks ago issue still happens. I have also unplugged it from a power strip and plugged it back into a wall socket. A couple days ago i reset my windows back to 8 and updated it back to 8.1 just in case there were issues.I also do not overclock.

Sounds like a bad PSU. Can't maintain the load the GPU demands. See if turning the game settings (including resolution) down to the very lowest makes a difference. If it does, it is for sure the PSU.

Lowering the settings did work i never lowered the resolution before. What PSU would you recommend?

Since you won't be adding a 2nd gfx card in that mITX board, you won't need 750W. With an 84W processor and a 230W gfx card, I'd stick with Nvidia's recommendation of a 600W or better PSU. There are many top quality PSUs available. I'm kinda partial to XFX: http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=100007657%2050001669%20600479295&IsNodeId=1&name=600W%20-%20699W
I would imagine a modular PSU would be helpful if that mITX board is in a small case.

I personally go with Seasonic since they're the top quality brand. A bunch of other companies actually use rebranded Seasonic's (CORSAIR especially). I'd also go with fully modular since it's a pain in the rear to do cable management with a bunch of cables you don't need or use. http://www.newegg.com/Product/Product.aspx?Item=N82E16817151104


BTW, other issue might be thermal throttling from dust build up or bad heatsink connection / thermal paste.

Thanks for the help. I will change the psu and reply if the issue persists.
