Two-In-One: This 15-pin SATA power Y-splitter cable turns 1 SATA power port into 2 when SATA power is running low, providing a convenient solution for adding more connections to existing power supplies with limited SATA power ports. Plug and Play: Simple installation requires no driver installation. The flexible and sturdy cable makes adding another disc drive simple and quick, and the extended design allows for better cable management in tight spaces and a cleaner computer case.

REVERSE TRANSFER: Hard drive power cables support 3.3V, 5V, and 12V supply voltages between SATA I, II, and III hard drives and the power connection without degrading performance.
