Do I have a faulty PSU?

Hi all!
I am new to the community and I really need your help to figure out this issue. Last month, I built myself a computer and thought it was going to go fine once I put it together. However, when I try to load up Starcraft 2 and join a match, it automatically shuts down. To make sure this wasn't a heat problem, I played 10 youtube videos on HD and was running Starcraft 2 Campaign and the max temperature was 60C (Speed Fan). I don't know any other issues that can pertain to this problem other than over heating and a faulty PSU. My build is below:

    No, the screen just goes black and reboots. This just happens with Starcraft 2.
    Thanks

    What component showed the 60C temp reading?
    If that was the CPU, that is a bit on the high end. If it was the GPU it is o.k. and within limits.
    Make certain your CPU cooler/heatsink is properly and firmly seated on the CPU.
    Will StarCraft 2 play on lower graphical settings without the PC shutting down?
    And yes, it could be your PSU; but I would leave that as the last thing to check. Take a look at this Tom's link for some info about the Corsair CX series:
