So I bought a Thermaltake 600w (http://bit.ly/1CI49bQ), and I'm afraid of running it all night because of a few issues. First, it won't turn on unless the plug for the PSU is seated in a specific way (it can move around; if you mess with it at all, the computer shuts off.) I'm afraid of leaving it run all night to install games because of this for some reason. It works completely fine, it's just the seating issue on the PSU plug.
