Windows 7: Random shutdown problem - Corsair Builder Series CX430W ?

Random shutdown problem - Corsair Builder Series CX430W ?

Hi all!

My system started having random shutdowns recently. I suspect it's the PSU but I really don't know how to evaluate it.

The symptoms: Under heavy load (playing Dragon Age for about an hour or a bit more) the PC just shuts down. No BSOD, no error message, nothing, it just shuts down. I can't turn it back on right after that, only after waiting a couple of minutes and/or switching the PSU on and off (I'm not really sure which of these solves the problem). Such problem never occured under normal load so far.

I know that CX430 has multiple different voltage protections built in, I'm just not sure which one gets triggered - to be honest I'm not even sure if it's the PSU, but the fact that I can't turn it back on immediately afterwards suggests some sort of circuit breaking mechanism behind it.

Any suggestions? How could I confirm that it's the PSU? What else can be the cause?

The system specs are these (the PC was built in last June):

PS: I'm not sure if this problem belongs here as there is no BSOD, admins, please move it if necessary

Could be power, overheating, or a hardware fault. You can test the PSU using Britton30's PSU Testing

Download and install the appropriate version of HWINFO: HWiNFO32 for 32-bit Windows 7 or HWiNFO64 for 64-bit Windows 7 to check hardware temperatures by running in sensor-only mode. Start logging the temperature through sensor-only mode when the computer first starts, and let it run until the computer shuts off during stress.

Save the CSV file in a place you will remember, and then compress the CSV file to a zip file and upload to here for us to analyze by following the steps in Screenshots and Files - Upload and Post in Seven Forums.

You can also run the following stress tests to check for hardware errors causing the system to fault:
