Product Description
This SATA 15Pin connector splitter cable converts a single SATA power plug into two independent outlets,
allowing two drives or other low-voltage electronic modules to share one PSU rail. The male input mates with a
standard SATA power socket, while the two female connectors supply stable DC power to HDD, SSD, optical drives or SATA-powered accessories.
Color-coded copper wires provide clear identification of 12 V, 5 V and ground lines,
helping avoid wiring mistakes during installation. Robust molded
housings and crimped terminals ensure reliable electrical contact and mechanical strength under
vibration, making this harness suitable for desktop PCs,
workstations, NAS units and compact server chassis. For OEM projects, the splitter can be tailored with
specific lengths, wire gauges, or integrated into larger
multi-branch wire cable looms and PCB power boards to match different enclosure layouts or light
automotive data-recording systems.

Applications
Supplying power from one SATA output to two HDD / SSD in a PC or
NAS enclosure
Adding an extra SATA power outlet for optical drives, fan hubs or
LED controllers without changing the PSU
Power distribution in small server racks, DVR / NVR recorders and industrial control cabinets
Retrofit or upgrade projects where existing harnesses lack
sufficient SATA 15Pin outlets
Custom storage cages and modular backplanes using SATA-style connectors for easy swap of power branches
Precautions
Confirm the total current draw of both devices so the PSU rail and
splitter terminals are not overloaded.
Check alignment when inserting male and female connectors; forcing the plug may bend the pins or damage the housing.
This product carries DC power only and does not replace SATA data cables; use separate data lines for signal transmission.
Avoid sharp bends and contact with hot components or moving fan
blades to maintain insulation integrity and service life.
Customized harnesses with different pitch interfaces, additional
power branches or specific routing requirements can be produced for
batch orders.
