New GeForce GTX 660/PSU = computer reboot, Why ?

[Alans74]

I recently bought a new PNY GeForce GTX 660 card with a Thermaltake TR2 600W supply. I installed everything as best as I could along with help from a friend of mine. The computer works great ! turns on, browsing around the internet, watching youtube, etc, BUT... when I go to Steam and fire up a game after about 5 min of playing time, if that, the computer shuts off and reboots without warning. Wouldn't the PSU be enough for this card ? What could I be missing?

I would like to add I am not the most tech savvy person when it comes to computers, but I'm doing my part in trying to learn as much as possible about them, thus why I wanted to join this forum.

It seems to be your PSU, I'd advise you get rid of it before it damages any thing else. http://www.tomshardware.co.uk/forum/317675-28-thermaltake-600w-problem

I have a 620W Seasonic PSU and it powers my 660 O/C card with ease. Your PSU might be old and tired or just not of that great of quality and not able to truely hit it's 600W rating.

Both components are brand new I bought online for cyber monday deals. The PSU from Thermaltake could be bad ? The case of the computer is off when I'm playing and I can hear a faint click like something is trying to turn on or off moments before it shuts off.

Yeah, you may give thermaltake a call.

Look at the thread I linked, it says that the Thermaltake TR2 isn't high quality and that you should replace it. Get a good PSU from a good manfacturer for example Seasonic. Seasonic 620W is a good a PSU or you could get an XFX 550W which is also a good psu and should power your GTX 660 with ease
