This 15-pin SATA power cable is designed to power SATA devices, such as SATA hard drives, from a 4-pin Molex power cable. It facilitates the conversion of power sources, allowing you to connect a SATA device to an older Molex power connector. This adapter is ideal for users who need to add SATA storage or other SATA-powered components to a system that lacks sufficient native SATA power connectors. The black colour family ensures it blends seamlessly with other components in your computer build.
