PSU SAFETY: Modular PSU-side cable pinouts are proprietary and model-family-specific. Never substitute a modular cable by brand, connector fit, color, or appearance; use only the exact PSU maker-approved cable for the exact PSU model and revision.

Manufacturer specifications

Manufacturer partStarTech.com SATAPOWEXT12
Connector / pin countOne 15-contact SATA power plug to one 15-contact SATA power receptacle.
Wire gauge / length18 AWG; 12 in (304.8 mm).
Compatible PSU familyStandard SATA power device-end connector on an ATX PSU lead, for SATA drives/peripherals. A modular PSU must retain its own manufacturer-approved SATA harness; this extension connects at the standard drive-end SATA plug and is not a substitute for or interchangeably wired PSU-side cable.

Power and safety caveats

For SATA-powered devices within the PSU, original harness, and connector ratings. Do not overload a single daisy-chain or infer power capability from connector fit. Check for melted housings, discoloration, loose contacts, or damaged insulation.

Case clearance and routing

The 12 in length is the extension body. Measure the drive-bay route, account for the plug latch and bend space, and keep the cable clear of drive rails, fans, sharp cutouts, and side-panel compression.
