Computer Shuts off when playing games

[Mason_10]

When I play games my computer turns off if I don't bring down my clock speeds and voltage.
I have to bring the voltage and clock speeds as low as I can or my computer turns off when playing games.

It's your PSU. It only has 240 watts on the 12V rail. It probably about a 300W PSU.

I've never heard of the brand, so I have to agree with this.

Go to this thread and pick any PSU from the Tier 1/2 sections. The one you linked is not bad but for not much more you can get something much better!
