How many pins are in Serial ATA power connector?
fifteen pins
It is a wafer-type connector, like the SATA data connector, but much wider (fifteen pins versus seven) to avoid confusion between the two. Some early SATA drives included the four-pin Molex power connector together with the new fifteen-pin connector, but most SATA drives now have only the latter.

A jumper pin is a rectangular connector that creates a circuit between two pins. Seagate SATA drives have four pins, while Western Digital SATA drives have eight pins, with the additional pins to be used by technicians or your network administrator for powering up the drive while in standby mode.
Why do SATA power connectors have so many pins?
Each voltage transmits through three pins ganged together, because the small contacts by themselves cannot supply sufficient current for some devices. (Each pin should be able to provide 1.5 A.) So that is nine pins needed for power, though very few (if any) drives use the 3.3 V lines, plus a few for ground.
