5.Locate one of the power supply cables that lead from the power supply (behind the horizontal drive bays). The power supply cables may be secured in a plastic band on the side of the power supply. If so, unfasten the band to access the cables; you can use any one that is free. (If your drive requires a small power supply cable connector, use the small connector.)
6.Position the power supply cable connector so that its notched corners line up with the notched corners of the power supply connector on the hard disk drive. Make sure the holes fit over all the pins and then push in the connector firmly.

If you do not align the cable connector correctly, you could severely damage your hard disk drive when you push it in.
