If your Serial ATA HDD has both 4-pin and 15-pin connectors at the
back, use either the 15-pin SATA power adapter plug OR the legacy
4-pin power connector. DO NOT use both to prevent damage to
components and to keep the system from becoming unstable.

the back of the drive, then connect the other end to a Serial ATA
connector on the motherboard. See page 4-5 for the location of the
Serial ATA connectors.
6. Connect a 15-pin Serial ATA power plug from the power supply unit to
the 15-pin power connector at the back of the drive.
