Product Description
This assembly integrates SATA power and data connections into one neat harness. A 4-pin power connector feeds a SATA 15-pin power plug, while several shielded right-angle SATA 7-pin cables link directly to HDDs or SSDs. The design reduces cable clutter inside servers and desktop systems, improving airflow and simplifying drive installation.
Stranded copper conductors and tightly controlled impedance maintain low-loss power and high-integrity signal transmission up to 6 Gb/s. Right-angle SATA connectors are ideal for narrow chassis or back-to-back mounting, helping the cables exit parallel to the drive surface. The harness can be customized for different drive counts, cable lengths, and connector types to match your storage layout or PCB headers.

Applications
Internal cabling for tower or rack-mount servers, NAS enclosures, and RAID storage systems.
Desktop workstations and gaming PCs where multiple SATA drives share a compact cable set.
Industrial PCs, DVR/NVR recorders, and embedded storage modules using SATA HDDs or SSDs.
OEM storage backplanes or custom PCBs requiring pre-terminated SATA data and power harnesses.
Precautions
Verify that the total current of all drives does not exceed the PSU rail and cable rating.
Align keyed SATA connectors correctly to avoid bending contacts or damaging drive sockets.
Do not sharply bend or crush the red SATA data cables, especially near the right-angle boots.
Keep SATA data lines separated from strong EMI sources such as high-current motor leads.
Periodically inspect harnesses in high-temperature or high-vibration environments and replace any cable showing cracked insulation or discolored terminals.
