I took ALL the insides out of the PC power supply. The only thing I'm powering is the fan. Just clip the wires leading from the fan and route those fan lines outside the PC power supply. Those are my red/black wires in the closeup pic of the PC power supply. All you should have is an empty power supply box and the fan. Then you just have a black, red, and possibly yellow wire. forget about the yellow wire if you have one, that just sends a speed signal to the motherboard, which you do not need. Then I took a DC wall adapter power supply, such as a cell phone charger. Look for pic of the AC adapter further up the post. Your fan will say something like 12v and .19A. You just need any power supply which supplies 12v and more A(mperage) than your fan requires. There will be a sticker or stamp on the power supply which gives you it's rating.
Clip the end of the AC adapter wire that would normally connect to your cell phone or whatever else the adapter goes to and route that line into the cabinet through the co2 line hole. The wall part of the adapter is just plugged into a regular wall outlet outside the unit. The AC adapter has two wires also. I wired one to the red and one to the black from the fan. The power supply I had has a picture on it with a positive on one side and a negative on the other. I took that to mean the wire coming out of the power supply on the right was positive (and it had some print on it) and the opposite wire was negative. I do know that red is positive and black is negative, and in my experience, wires with the print on them are generally positive, so I simply twisted them together with their respective wire from the fan and it worked. The yellow wire connectors you see are where I connected my AC adapter to the fan wires.
