Power Connector

Hard disk drives use a standard, 4-pin male connector plug, that takes one of the power connectors coming from the power supply. This keyed, 4-wire plastic connector provides +5 and +12 voltage to the hard disk. See this discussion of drive power plugs in the power supply reference for more information.

"4, 3, 2, 1" pin markings on the logic board, and the
