Connector and Length

This cable bridges a Mini SAS HD SFF-8643 port to a U.2 SFF-8639 drive while supplying power through a 15-pin SATA connector. The assembly measures 80CM (2.6FT) and uses a direct-angle layout for tight routing inside compact chassis.

Builders Adding U.2 Drives

Suits anyone connecting a 2.5-inch U.2 NVMe SSD to a backplane or HBA that exposes an SFF-8643 interface and has a spare SATA power lead. Not intended for M.2 drives, pure SAS hard disks, or systems that lack a free SATA power output.

Straightforward Installation

Plug the 36-pin SFF-8643 male end into the controller, seat the 68-pin SFF-8639 male end on the drive, and attach the 15-pin female SATA power tap to the PSU. Common issues include forgetting the power connection or exceeding the 80CM reach in larger enclosures.

Questions about this item

What host connector does my controller need to accept this SFF-8643 to SFF-8639 cable?

The cable plugs into a Mini SAS HD SFF-8643 36-pin male port on your controller or backplane.

Will the cable carry power to a 2.5-inch U.2 NVMe drive without an extra power lead?

Yes, a 15-pin SATA female power connector is built into the SFF-8639 end to supply the drive directly.

How can I confirm the link is running at the expected 12 Gb/s rate after installation?

Check the controller BIOS or OS tool for a negotiated PCIe Gen 3 x4 link showing 16 GB/s aggregate throughput.
