Slim SAS SFF-8643 male to U.2 SFF-8639 cable with SATA power supply, 80 cm long, featuring Amphenol connectors

This cable connects a U.2 NVMe SSD in the SFF-8639 form factor to a SlimSAS SFF-8643 interface on a compatible controller card, motherboard, or expansion card.

Since the SFF-8643 interface carries only data signals without power, this cable includes a dedicated 15-pin SATA power connector, which is essential for properly powering the connected U.2 SSD.
