The Cable Matters 4-Pin Molex to SATA Power Cable Adapter is a convenient toolbox for you outside of building, upgrading or repairing your computer. It connects the new SATA internal hard drive, optical drive and motherboard to a power supply with a traditional lp4, 4-pin Molex connector. Recycle the old power supply for repair or replacement. When the SATA ports are all occupied, use the additional Molex ports on the power supply.
