This SATA power splitter cable features a SATA male power connector that connects to a single computer power supply SATA connector, & breaks out into two SATA power connectors. The SATA power splitter/Y-cable overcomes the limit of the number of SATA drives that can be installed in the system based on available PSU power connections, & eliminating the cost of having to upgrade the power supply to accomodate an additional SATA drive.
