Not to insult but assuming you can do basic electrical work. And your PS can supply enough current on the 12V bus. Order the molex to p4 adapter above. Get some extra wire, butt connecters, solder, and a soldering iron. Cut the molex connector off of the molex to p4 adapter. Make the length of wire from the adapter longer using the butt connectors and the extra wire. Open the power supply and solder the 12 V wires to the 12V bus and the ground wires to the ground bus.
