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
Precautions
Check the PSU load capability before adding multiple devices through one adapter; avoid exceeding the rated current of the SATA rail and 4Pin terminals.
Confirm correct orientation when inserting the SATA and 4Pin connectors; forced mating may damage the housing or pins.
This adapter is designed for power lines only and not for high-speed data signal transmission.
Use in clean, dry environments; contamination of contacts will reduce conductivity and may cause overheating.
For projects requiring cabling, angled housings or integration with other power connector types, customized versions can be supplied for volume orders.
