The ECOPMAX Mini ATX 6 Pin to SATA Power Adapter Cable is designed for internal storage power expansion in compatible Mini ATX, small form factor, and brand-name desktop computer cases. It converts a Mini ATX 6 pin power output into one standard SATA 15 pin connector and one SATA 6 pin connector for compatible storage devices. This cable is useful for adding or replacing power connections for SATA HDDs, SSDs, and optical drives in compact PC builds. The cable layout includes a longer main cable section and a shorter branch cable, helping with internal routing in small cases where space is limited. It is suitable for users upgrading storage, replacing a missing internal power cable, or expanding drive support in compatible Mini ATX systems. Please check your motherboard or case power port, Mini ATX 6 pin pinout, SATA device power requirement, cable length, and internal clearance before installation.
