The final test... ...
Thanks, Cabbs. You've been a huge help, man. I think, tomorrow at work, I'm going to call up Newegg and see what I can do about getting another PSU.
Though, I did plug in my Graphics Card and get a sweet taste of what's to come. I was running WoW at full settings around 70-fps. My PSU didn't blow out, but the card did get increasingly hotter while the FPS / screen-quality began decreasing, so I took it out before anything bad could happen.
