Molex 67582-0000 used for cable connector and Molex 67581-0000 used for terminals connector.
The SATA standard specifies a power connector sharply differing from those used by PATA drives and many other computer components. It is wafer-based, 15-pin shape. The seemingly large number of pins are used to supply three different voltages — 3.3 V, 5 V, and 12 V.
Each voltage is supplied by three pins ganged together (and 5 pins for ground). This is because the small pins cannot supply sufficient current for some devices. One pin from each of the three voltages is also used for hotplugging. The same physical connections are used on 3.5-inch and 2.5-inch notebook hard disks.

Pins 3,7,13 are pre-charge. Pin 11 may be used for other purposes than GND.
Pins 1, 2, and 3 are optional as well, as evidenced by some adapter cables that connect the drives to older PSUs. These are usually Y-adapters that have the four-pin drive connector on the other end.
