SMUGDESK 0.5m SFF8654 8i to Dual SFF8639 U.2 + 15Pin Cable

SKU CH-7JKB-6TNWH

Connects an SFF8654 8i Slimline SAS port to two SFF8639 U.2 NVMe drives with integrated 15pin power over .5m of 85ohm copper at 24Gbps

  • Converts SFF8654 8i to dual SFF8639 U.2 with 15pin power for NVMe SSDs
  • Delivers 24Gbps bandwidth for enterprise storage and data center workloads
  • 85ohm copper wire minimises signal loss and crosstalk at high speeds
  • Integrated 15pin power removes separate cables, simplifying server wiring layout
  • .5m length fits short-range high-density chassis and backplane connections

Slimline SFF8654 to Dual U.2

This 0.5m cable converts an SFF8654 8i Slimline SAS interface into two SFF8639 U.2 ports with an integrated 15pin power connector. It uses precisiontuned 85ohm copper wire to deliver 24Gbps bandwidth for U.2 NVMe SSDs in enterprise servers and storage backplanes.

Server builders adding U.2 NVMe to Slimline

The cable suits administrators who need a short, highdensity link between a Slimline SAS controller and dual U.2 drives with combined data and power. It does not suit installations requiring a longer run between controller and backplane, builds that use a different drive interface, or chassis that cannot accommodate the 15pin power pinout.

0.5m length for dense chassis

The halfmetre reach is the dimension that determines fit in highdensity server enclosures. Verify the controllertobackplane distance before ordering, as the fixed length cannot be extended and a longer cable would be needed for wider layouts.

Questions about this item

What connector does the 15pin power plug into on the U.2 drive?

The integrated 15pin power connector attaches directly to the U.2 NVMe SSD power pins, removing the need for a separate power cable.

How do I connect the SFF8654 8i end to the controller?

Insert the Slimline SFF8654 8i plug into the matching SAS controller port until the latch clicks; the dual SFF8639 U.2 tails then route to each drive bay.

When should I replace this 85ohm copper cable?

Replace it if the latch tabs break, pins bend, or signal errors appear on the 24Gbps link during drive diagnostics.
