Product Description
This adapter harness combines a SATA 15-pin power connector with one 4-pin Molex and one 6-pin auxiliary power connector. It enables a single SATA power source from a PSU to feed devices that still require classic peripheral power and auxiliary power interfaces.
The assembly uses stranded copper conductors with thick insulation for reliable power transmission and reduced voltage drop. Secure crimped terminals and locking housings provide stable mating, minimizing the risk of intermittent contact in high-vibration environments such as servers or industrial equipment. Color-coded wires simplify identification of 12 V, 5 V, and ground lines during installation.
Custom configurations are available, including alternative connector brands, different wire gauges, and special pin assignments to match proprietary PCB or device requirements.

Applications
Powering legacy 4-pin peripherals and auxiliary 6-pin loads from modern SATA-based PSU harnesses.
Internal power distribution inside desktop PCs, workstations, mining rigs, and server chassis.
Industrial control cabinets where SATA power rails need to be adapted to board-level or device-level connectors.
OEM custom harnesses for storage systems, test equipment, and low-voltage automotive or embedded electronics.
Precautions
Verify the total current of all connected loads does not exceed the rating of the SATA rail, wires, or connectors.
Confirm pin assignment and voltage mapping for each connector before installation; incorrect wiring can damage drives, GPUs, or control boards.
Do not use this adapter to power devices with current requirements beyond the PSU’s specifications or cable capability.
Avoid sharp bends, excessive pulling, or twisting near the connector terminations to prevent conductor breakage.
Ensure all connectors are fully inserted and latched; periodically inspect for discoloration, deformation, or loosened terminals during maintenance.
