The 4 pin connector is commonly referred to as a molex connector. Moles is a company however and makes many of the connectors that can be found in a computer. The actual part is a 5.08mm Disk Drive Power Connection System. Part numbers are15-24-4048 for the receptical, and 15-24-4557 for the vertical header. The three pin i am not sure of. Jake
