CLASSIFICATION: Internal power cables. Identify protocol, direction, pinout and exact cable revision before connection.

Interface and capability

Standard / protocolSerial ATA power connector. Connector appearance alone does not establish compatibility.
Endpoint / pinout15 contacts carry +3.3 V, +5 V, +12 V, grounds and staggered contacts; distinct from 7-pin SATA data.
Capability / limitsPower only; usable current and extension length are product-specific and depend on harness and device load.
Certification / lengthStandards define interface requirements, not every assembly’s performance. Certification, mode, current/power rating, direction and maximum length belong to the exact product/revision and complete channel; verify its manufacturer specification. Do not infer certification from connector shape or marketing terminology.

Compatibility & handling

  • Align the L-key; inspect temperature and contacts. A splitter does not add PSU capacity; avoid unverified high-current adapters.
  • Inspect connector keying, latch, contact condition, shielding, jacket and model/revision marking. Stop if contacts are bent, loose, scorched, corroded or mismatched.
  • Route without tension or sharp bends; follow product bend-radius, strain-relief, current and environmental limits. Test at the intended protocol and mode—physical fit is not a compatibility test.
