New computer systems tend to use SATA connections for storage drive options. As such, the power supply comes equipped with 15-pin SATA power connectors for providing the power the drives need to operate. There are still many users with data stored on the older IDE (PATA) hard drives that require access to these drives even while using the new systems. For those with legacy drive needs, a SATA 15-pin power to 4-pin Molex adaptor cable is available that allows you to connect a SATA power supply to an older IDE hard drive.
