PC Restarting when Gaming

  1. Hello, I recently built my own gaming budget build about a month ago. This is my build with the addition of 3 LED 120mm fans: http://pcpartpicker.com/user/caleb826/saved/pwYfrH.

    My PC is automatically restarting while playing games like Archeage and Alien: Isolation. For some other games, the PC does not restart. Recently, I have noticed that my PC will restart when I minimize Archeage. Sometimes it will not. There has been 2 or 3 incidents where my PC restarted, but the video did not show. I saw the CPU heatsink's fan was not running. I fingered some wires and it worked. The general issue of my PC restarting did not occur for the first week or two after the PC was built.

    I understand my PSU is only 430W and paired with a more intense GPU. When building the PC, I figured since my CPU requires little power, I would still fall well under 430W, as noted on the pcpartpicker link.

    The only things I have done to remedy this problem so far is update my BIOS. I have also performed a couple different stress tests, and they run fine for as long as I run them.

    Here are screenshots of my HWiNFO at about 25-27m after my computer was freshly booted up first thing in the morning: http://i57.tinypic.com/wso67p.jpg, http://i58.tinypic.com/2002n7r.jpg, http://i62.tinypic.com/6gy43r.jpg,
    I've seen my CPU reach temps up to 49C when near 100% usage at 3.2Ghz. Is that okay? If not, what should I do?

    I see that my +12V is at a max of 11.880V. Is that okay? If not, does that simply mean I must replace my PSU? What do the different voltages mean? What does it mean to be under or over a specific voltage?

    I see that my GPU's max clock is 1120.0Mhz, but the memory's max clock is 1399.0Mhz. Is that okay? If not, what exactly does that mean and how would I go about fixing it?

    Thank you for taking the time to read this; I really hope to learn as much as I can about these issues before I (probably) have to buy new parts to fix it. If you need any screenshots of any other testing software, please just let me know.
