If you want to control a fan with it, you take a +12v and ground wire, strip it, and stick the metal tip into the 3-pin fan connector. The negative (black) goes to the ground, and the positive (usually red, which actually doesn't make sense, but it is anyway) goes to the +12v.

look at the picture. It has a +12 in and a ground in, then a +12 out and a ground out, which is switched on and of by the box (reciever) and wireless transmitter. You have to ignore the word molex.

Will this PSU run my card? If you're having to ask, it probably won't. PCI-E requires 26 amps at 12 volts. That's a 650W PSU. Power Supply Info and Selection
Why is my CPU hot? Info on thermal compounds & application
