The StarTech Latching SATA Power Y Splitter Cable (15.2cm) features a SATA 15-pin plug that connects to a single computer power supply SATA connector and breaks out into two latching SATA 15-pin receptacles, which enables you to connect two Serial ATA drives to a single SATA power connection on the computer power supply.
The latching SATA power connectors ensure a secured connection to the drives, preventing accidental disconnects, while the Y-adapter power split eliminates the cost of having to upgrade the power supply to accommodate an additional SATA drive.
