SMUGDESK Gen5 MCIO SFF8654 4I to SAS SFF8639 U.2 Cable with 15Pin SATA Power .5M

SKU CH-CJMH-Z4PAS

Connects an MCIO SFF8654 4I port to a U.2 SFF8639 drive with integrated 15-pin SATA power, delivering 30Gbps over .5M premium copper

  • Gen5 30Gbps bandwidth for enterprise storage speed
  • 15-pin SATA power delivers data and power to U.2 NVMe SSDs
  • MCIO SFF8654 4I to SAS SFF8639 direct connectivity
  • Premium copper wire minimises signal loss and interference
  • .5M short length enables clean routing in compact chassis

Gen5 MCIO to U.2 Cable with SATA Power

This 0.5 metre harness links a Gen5 MCIO Slimline SFF8654 4I port to an SFF8639 U.2 NVMe drive while delivering power through an integrated 15 pin SATA connector. It targets server builders and storage integrators who need a direct, single cable solution for adding U.2 solid state drives to enterprise backplanes or RAID controllers. The short length keeps internal routing tidy in dense chassis where space is at a premium.

Thermals, Noise and Power Draw

Passive copper construction generates no heat of its own and adds no acoustic noise to the system. The cable simply conducts the 30 Gbps signal and the auxiliary 15 pin SATA power lines between the host and the drive. Power consumption is limited to the negligible resistive loss of the conductors, leaving the drive and controller to determine the overall thermal envelope.

Bundled Accessories and Software Impact

No software, drivers or additional adapters are included; the cable is a pure hardware interconnect. The integrated 15 pin SATA power plug removes the need for a separate power lead or Y splitter, reducing cable count and potential failure points. Builders gain a cleaner harness and faster deployment in storage arrays, servers and data centre expansion projects.

Questions about this item

How do I connect the 15-pin SATA power plug when installing this MCIO 8654 to U.2 8639 cable?

Route the .5 m harness from the MCIO 8654 4I port to the U.2 8639 drive bay, seat both data connectors firmly, then attach the 15-pin SATA power plug to a free SATA power lead from the PSU; the drive will not spin up without that power connection.

What part of this cable is most likely to need replacement after extended use in a server chassis?

The 15-pin SATA power connector and the latch tabs on the MCIO 8654 and U.2 8639 ends endure the most insertions; if a latch snaps or a pin bends, replace the whole .5 m harness rather than re-pinning.

At what sustained throughput does this 30 Gbps copper harness hit its practical limit?

The assembly is rated for 30 Gbps; continuous workloads that saturate that bandwidth — such as multiple U.2 NVMe drives streaming large sequential writes — will reach the cable's signalling ceiling before any other component.
