SMUGDESK .5M SFF-8643 to SFF-8639 U.2 SAS Cable with 15-Pin SATA Power

SKU CH-KTV1-YEB64

A .5 m SFF-8643 to SFF-8639 U.2 cable with 15-pin SATA power for 12 Gbps NVMe SSD connection in servers and workstations

  • 12Gbps bandwidth for high-speed U.2 NVMe SSD data transfer
  • SFF-8643 to SFF-8639 connects HBA RAID card directly to U.2 drive
  • 15-pin SATA power connector supplies stable power to prevent drive shutdown
  • .5m length enables flexible internal routing in server and workstation chassis
  • Multi-layer shielding reduces signal attenuation for reliable heavy-load operation

Direct U.2 SSD link for servers and workstations

This .5 metre cable connects a Mini SAS HD SFF-8643 port on a RAID controller or HBA directly to a U.2 NVMe SSD using the SFF-8639 interface. It targets system builders expanding high-speed storage inside server, workstation or enthusiast chassis.

Integrated 15-pin SATA power feeds the drive

The built-in power connector draws from a standard SATA supply rail, delivering the current a U.2 SSD needs for sustained operation without a separate power adapter. This single-cable approach simplifies drive installation and reduces the number of connections that can come loose.

Shielded construction keeps signals clean at 12Gbps

Multi-layer shielding suppresses electromagnetic interference inside crowded enclosures, helping maintain the rated bandwidth during heavy, continuous workloads. The short length eases routing in tight spaces, though builders needing longer runs or additional drive ports will need a different cable.

Questions about this item

Will the 15-pin SATA power connector need replacement after extended use?

The 15-pin SATA power connector is a standard interface designed for the cable's lifespan; no periodic replacement is expected under normal internal server or workstation operation.

What limits the 12Gbps bandwidth during sustained heavy-load transfers?

The 12Gbps rate is the cable's maximum specification; actual sustained throughput depends on the connected U.2 NVMe SSD, HBA or RAID controller, and system workload.

Does the .5M length or shielding affect heat or noise when running all day?

The cable is passive with multi-layer shielding, so it generates no noise and negligible heat; the .5M length aids airflow without adding thermal load.
