Mini SAS to U.2 Cable

This new cable links a Mini SAS SFF-8643 port to a U.2 SFF-8639 SSD. It carries 12Gb/s data and includes a 15-pin SATA power connector for 3.3V and 12V supply. The assembly measures 1.64ft and supports PCIe 3.0 four-channel operation.

Suits U.2 NVMe SSD installs

Builders adding a U.2 NVMe drive to a board or HBA with an SFF-8643 connector can use this cable. It is not for systems lacking that specific port or drives with a different interface such as M.2 or standard SATA.

SFF-8643 to SFF-8639 with SATA power

The single deciding specification is the Mini SAS SFF-8643 to U.2 SFF-8639 pinout combined with the integrated 15-pin SATA power lead. If your host port or drive connector differs, this cable will not fit.

Highlights

  • Connects PCIe SFF-8643 port to U.2 NVMe SSD
  • 12 Gb/s SAS link enables high-speed NVMe operation
  • Integrated 15-pin SATA power delivers 3.3 V and 12 V to the drive
  • Four-lane PCIe 3.0 pathway supports full NVMe bandwidth
  • 64 ft length fits compact chassis builds

Questions about this item

Will the 12Gb/s SFF-8643 connector work with my older 6Gb/s SAS backplane?

The cable carries a 12Gb/s SAS link; it will negotiate down to 6Gb/s when plugged into a 6Gb/s backplane, so the U.2 NVMe SSD will still operate at the slower speed.

How can I confirm the 15-pin SATA power lead is delivering 3.3V and 12V to the U.2 SSD after installation?

The drive should appear in BIOS or the OS device list and report its full NVMe capacity; if it is missing or shows power-loss events, check that the SATA connector is fully seated on the PSU.

Does the 1.64ft cable include the U.2 NVMe SSD or only the SFF-8643 to SFF-8639 assembly with integrated 15-pin SATA power?

Only the cable assembly is supplied — the U.2 NVMe SSD must be purchased separately.
