Yes, it is hooked directly onto my power supply. It heats up really, really fast.

I have managed to get the left screw out, but can't get the right one out now. If you look to the right of the right yellow arrow, you can see a lime green piece. This helps keep the power supply in place. Additionally, there are two screws to help out. If I can get both screws out, which will be like hell, I can just take the entire power supply box out and work with it from there , which would be a lot easier. The problem with doing that is that it's hard to unscrew both screws because of all the wires. This tower is jam packed full of stuff.
