Computer shuts down after playing games

[Supertoaster77]

I just installed a new PSU, a thermaltake tr2 600w, and after playing games after a minute or so it will just turn off the computer. The red pwer LED still works, but I need to turn off the PSU and then back on again in order to reboot the computer.
EDIT: Not it's not even after playing games. Now it just happens within two minutes of reboot.

What's your vga model?

What's your vga model?

If you mean graphics card, it's a Radeon HD 7850.

That's enough to power up this card. Did you check if all the fans, the one in the psu too, are working? It seems like an overheating.

All fans are working. I'm almost certain it's not overheating.

I have, and it rarely goes above forty, thanks to liquid cooling.

Try reinstalling your old psu if it still works. If it works, your psu is bad. If same error, try installing CPUID Hardware Monitor and printscreen the temps and voltages. I also thought it could have been a overheating issue. Try replugging all power connections.

Try running your computer with your gpu card unplugged (power and all) and use your motherboard's stock vga/dvi/hdmi display.

It's starting to look like it's just a bad PSU, as I let it sit on idle for roughly an hour and it just shut down now.

Probably PSU issue then. Did you try with your last one, I mean, if it is at least 500W? If it works, ask for another PSU and you'll be good to go. I personally think cooler master is the best brand, but others like thermaltake are good as well.
