My computer Shuts down when I load up a game

[nailmon96]

Hi I'm new here and I was wondering if it would be possible if someone could help me with a problem I'm having.

Recently i have installed a new graphics card and when i try to play games on my PC the system just turns off. This has happened with me on Metro Last Light and Blood Dragon and i have no idea what's going on.

My specs:
CPU: Amd Phenom ii X4 955
Motherboard: Asus m4a79xtd evo
Memory: 16GB DDR3
GPU: Asus DirectCU II GTX 660ti
PSU: ACE 500W BR PSU

Any answers would be greatly appreciated, thanks.

+1 Ace PSU are bad. You could damage your computer is you get electrical problems.
Get a corsair, antec, cougar or at worse a thermaltake or rosewill.
