StarTech SATAPOWEXT8 8-inch SATA Power Extension
StarTech.com manufacturer part SATAPOWEXT8. This record documents only this specified cable assembly; connector fit is not evidence of a matching pinout or PSU compatibility.
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

Power and safety caveats
For a SATA-powered device within the PSU and original harness ratings. This extension does not create an additional PSU rail or increase current capacity; do not overload a daisy-chain and do not use the SATA power interface for a GPU adapter.
Case clearance and routing
The extension body is 8 in long. Confirm reach to the intended drive and reserve room for the connector latch and a non-strained bend; avoid pinching at the tray or panel and keep clear of fan blades.
