Slimline SAS SFF8654 4i 38P to U.2 SFF8639 cable with SATA 15pin power, 31.49in 32AWG

SMUGDESK

SMUGDESK SFF8654 4i 38P to SFF8639 U.2 SAS Cable with SATA 15Pin Power 31.49in 24Gbps 32AWG

SKU CH-N63W-GYH5J

Connects a Slimline SAS SFF8654 4i host port to a U.2 SFF8639 drive with integrated SATA 15‑pin power, 24Gbps bandwidth, 32AWG copper and 31.49in length

  • Connects Slimline SAS SFF8654 4i to U.2 SFF8639 drives for enterprise storage expansion
  • 24Gbps bandwidth supports U.2 NVMe SSDs and high-performance SAS drives
  • Integrated SATA 15pin power cable simplifies internal server wiring
  • 32AWG pure copper construction reduces signal loss and crosstalk
  • 49in length enables neat routing in rackmount servers and RAID backplanes

Enterprise Storage Link

This cable connects a Slimline SAS SFF8654 4i 38pin host port to a U.2 SFF8639 drive interface. It supports 24Gbps data transfer for U.2 NVMe SSDs and highperformance SAS drives. The integrated SATA 15pin male power connector supplies stable power directly through the cable assembly. It is built for internal server and RAID backplane deployments.

Compatibility Check

Verify that your host controller or backplane provides a Slimline SAS SFF8654 4i 38pin connector. Confirm the target drive uses a U.2 SFF8639 interface and requires SATA 15pin power delivery. Ensure the 31.49inch length suits your chassis routing path between the controller and drive bay. This cable does not serve standard SATA data ports or M.2 slots without the correct U.2 adapter.

Build Quality && Routing

Premium 32AWG pure copper conductors reduce signal loss and crosstalk for consistent longterm performance. The Slimline SAS and U.2 connectors feature a slim profile designed for highdensity server environments. Combined data and power connectors simplify internal wiring by eliminating separate power runs. The fixed 31.49inch length supports neat cable management inside rackmount systems.

Questions about this item

What connectors and cables are included with the SMUGDESK SFF8654 4i 38P to SFF8639 U.2 SAS Cable?

The cable assembly includes a Slimline SAS SFF8654 4i 38-pin connector on one end, an SFF8639 U.2 SAS connector on the other, and an integrated SATA 15-pin male power cable. No additional cables are included.

When should I choose the 31.49-inch 32AWG version versus a different length or gauge?

Choose this 31.49-inch 32AWG cable when routing inside rackmount servers or high-density storage systems where the fixed length matches your backplane-to-controller distance and the thin gauge eases cable management.

What does the 24Gbps rating mean for my U.2 NVMe SSD or SAS drive in a real server?

The 24Gbps rating indicates the cable supports the full bandwidth of 24G SAS and PCIe Gen4 U.2 NVMe drives, so your SSD or SAS drive can run at its rated speed without the cable becoming a bottleneck.
