Product Description

This compact SATA 15Pin to 4Pin connector adapter allows a modern SATA power rail to drive legacy 4Pin peripheral devices without extra wire cable assemblies. Precision-formed copper alloy terminals provide low-resistance power transmission for 5 V and 12 V circuits, supporting hard drives, case fans, pumps and other low-voltage electronic loads.

The SATA side mates with any standard PSU or backplane SATA power socket, while the 4Pin side presents a familiar peripheral female connector using 4.20 mm pitch power pins. A rigid one-piece housing saves space compared to traditional cable adapters and improves mechanical stability in dense PC, server or embedded systems.

This adapter can be used as a quick field solution or integrated into custom assemblies where a SATA power source must feed older devices or PCB terminals built around 4Pin interfaces. OEM customization is available for different markings, housing colors and special packaging for industrial or automotive distribution.

Applications 

Adapting SATA power outputs to 4Pin connectors for HDD/SSD, optical drives or legacy peripherals

Providing additional 4Pin power points for fans, pumps and LED light strips in desktop and workstation builds

Space-saving power conversion inside 1U/2U server chassis and compact industrial controllers

Lab and test setups where SATA rails are used as convenient low-voltage electrical sources for prototype PCBs

Retrofit and repair of equipment that mixes SATA-based PSUs with older 4Pin power standards
