Product Description
This cable assembly converts a standard SATA 15Pin power output into a compact 4Pin connector for PCB or small device interfaces. Three color-coded wires (yellow, red, black) clearly distinguish 12 V, 5 V and ground circuits, ensuring safe routing of power and low-current signal lines to hard drives, fan hubs, LED boards and other electronic modules.
The harness uses stranded oxygen-free copper conductors and high-quality crimp terminals to maintain low resistance and reliable electrical transmission. The SATA plug mates directly with the PSU or backplane, while the 4Pin housing fits common 2.54 mm pitch PCB headers, making this cable ideal for upgrades, custom builds, and OEM harness customization in PC, server and industrial systems.

Applications
Supplying 5 V / 12 V from SATA power rails to PCB-mounted controllers or driver boards
Powering fans, pumps, or LED strips via a 4Pin PCB connector in desktop and server enclosures
Adding auxiliary power to embedded devices or expansion cards without redesigning the PCB
Test benches and prototype setups where SATA power is used as a convenient electrical source
Low-voltage electronic equipment in automation or light-duty automotive electronics using SATA-based power distribution
Precautions
Confirm the required voltage and pin definition on the 4Pin header before connection; incorrect mapping of pins can damage the PCB or peripheral.
The cable is intended for low to medium current loads; if multiple devices are connected downstream, ensure the total current does not exceed the SATA rail capability.
Avoid sharp bends or repeated flexing close to the housings to protect the crimp terminals and insulation.
Keep the harness away from hot components, moving fans and metal edges; fix the wire cable with clips or ties where necessary.
Variants with different pitch, wire gauge, length, additional branches or alternative male/female connectors can be produced for project and batch orders.
