Product Description
This cable assembly integrates SATA data and power into one compact harness. The drive end features a combined 7+15-pin SATA connector, while the opposite side offers a standard SATA 7-pin host plug for data and a small micro power connector for the PSU or PCB header.
Shielded SATA cable ensures stable high-speed signal transmission up to 6 Gb/s, and thick copper power wires guarantee reliable 5 V and 12 V delivery to the drive. The slim, flexible structure helps reduce clutter in tight chassis and improves airflow around HDDs and SSDs. Custom connector options and cable lengths can be provided to match different server, industrial PC, or storage layouts.

Applications
Internal wiring for servers, NAS enclosures, RAID subsystems, and DVR/NVR storage units.
Desktop or industrial PCs where the motherboard or PSU uses a small power header instead of a full SATA power cable.
OEM storage modules and backplanes that require a pre-terminated SATA data and power harness for fast assembly.
Custom embedded systems or instruments using 2.5"/3.5" SATA HDDs and SSDs as removable or fixed storage.
Precautions
Confirm the pin assignment on the micro power connector and PCB header before installation to avoid reverse polarity.
Ensure the total current drawn by the drive is within the rating of the PSU rail and cable gauge.
Do not sharply bend or crush the red SATA data cable, especially near the connector overmolds.
Keep SATA data lines away from high-noise power or motor cables to maintain good signal integrity.
Verify all connectors are fully seated and latched; periodically inspect for loose contacts or insulation damage in high-vibration or high-temperature environments.
