SMUGDESK M.2 M-Key to U.2 SFF-8639 Adapter Card 100cm Right Angle SATA 15P Power SATA 7P Data Cable

SKU CH-CMQM-Z6HND

Converts M.2 M-Key NVMe SSDs to U.2 SFF-8639 with 100cm right-angle SATA power and data cables

  • Converts M.2 M-Key NVMe SSD to standard U.2 SFF-8639 interface for server backplane connection
  • 100cm right-angle SATA 15-pin power and SATA 7-pin data cable enables tidy internal wiring
  • Professional PCB design with gold-plated contacts ensures stable high-speed PCIe signal transmission
  • Right-angle 90-degree plug prevents cable bending damage and optimises airflow in compact chassis
  • Plug-and-play compatibility with Windows, Linux and server OS for DIY server storage expansion

M.2 M-Key to U.2 SFF-8639 Adapter

This adapter converts an M.2 M-Key NVMe SSD into a standard U.2 SFF-8639 interface for direct connection to server backplanes and RAID controllers. It enables the reuse of NVMe drives in enterprise storage bays that accept U.2 SFF-8639 connectors. The product is intended for system builders integrating NVMe SSDs into server or NAS environments.

SATA Power and Data Cable Limits

The included 100cm combined cable supplies both SATA 15-pin power and SATA 7-pin data through a single right-angle assembly. The 90-degree elbow prevents excessive wire torsion in narrow rack cases and protects the inner core from fatigue fracture. This cable length and connector orientation define the physical reach and routing constraints inside the chassis.

NVMe M.2 M-Key Capacity and Compatibility

The adapter exclusively supports M.2 M-Key NVMe protocol SSDs and is not compatible with B-Key SATA M.2 drives. It handles continuous 24-hour high-load operation required by enterprise storage systems with a professional impedance-controlled PCB. Buyers needing to connect SATA-based M.2 drives or non-NVMe protocols cannot use this adapter.

Questions about this item

Should I choose this adapter for an M.2 M-Key NVMe SSD or for a B-Key SATA drive?

This adapter only supports M.2 M-Key NVMe protocol SSDs and is not compatible with B-Key SATA M.2 drives.

What does the 100cm combined cable provide once installed in a server?

The 100-centimeter right-angle cable integrates SATA 15-pin power and SATA 7-pin data, preventing wire torsion in narrow racks and improving airflow.

Which interface standard does the SFF-8639 connector follow and what does it connect to?

The SFF-8639 U.2 port connects to server RAID controllers, storage backplanes and JBOD enclosures via SFF-8643 cable.
