You will also need an internal power cable to supply the power to the internal drive. This is because the internal drive uses a moulded plug to connect the data and the power cable. Or you could saw the moulded plug into two to separate the power and the data connectors, but if there is additional accidental damage you would need to source a replacement for that cable!
