SKU CH-8FMM-84XXS

Connects a U.2 NVMe SSD to a Mini SAS SFF-8643 controller with integrated SATA power, 50 cm length

Cable Length 1m

  • Connect U.2 NVMe SSDs via Mini SAS SFF-8643
  • 12G SAS bandwidth for high-performance storage
  • Integrated SATA power delivers 3.3V and 12V to drive
  • 50cm length suits compact 2.5-inch drive bays
  • Compatible with Intel SSD 750, P3600, P3700

Mini SAS SFF-8643 to U.2 NVMe Adapter

This adapter cable connects a Mini SAS HD SFF-8643 port on a RAID or storage card to a U.2 SFF-8639 NVMe SSD. It includes an integrated SATA power connector that draws 3.3V and 12V from the power supply to run the drive. The 50cm length fits typical chassis layouts while maintaining a 12G SAS physical link for PCIe 3.0 four-lane operation.

Suited for RAID card installs, not direct M.2

Builders adding a U.2 NVMe drive such as the Intel SSD 750, P3600 or P3700 to a Mini SAS HD equipped controller will find this cable matches the required pinout and power delivery. It does not accept an M.2 drive directly; a separate M.2 to U.2 adapter would be needed for that form factor. Users without a Mini SAS HD SFF-8643 port on their host card should look at other connection methods.

SFF-8643 to SFF-8639 with SATA power

The single specification that decides fit is the Mini SAS HD SFF-8643 to U.2 SFF-8639 connector pairing combined with the SATA power tap for 3.3V and 12V input. This exact interface and power arrangement is required for the listed Intel U.2 SSDs and compatible add-in cards such as the ASRock U.2 or Gigabyte M.2 to U.2 Mini SAS models.

Questions about this item

What cables and connectors are included, and what extra parts are needed to run an M.2 NVMe drive?

The box contains a 50 cm Mini SAS HD SFF-8643 to U.2 SFF-8639 cable with an integrated SATA power connector for 3.3 V and 12 V supply. An M.2 to U.2 adapter is not included and must be purchased separately to connect an M.2 NVMe SSD.

Which SSD models and form factors are confirmed compatible with this 12 Gb/s adapter?

The cable supports U.2 SFF-8639 NVMe SSDs such as the Intel 750 series, P3600 and P3700 2.5" drives. It connects a PCIe 3.0 x4 RAID or add-in card with an SFF-8643 port to the U.2 SSD. M.2 drives require a separate M.2 to U.2 adapter.

What does the 12 Gb/s rating mean for real-world NVMe throughput over this 50 cm link?

The 12 Gb/s Mini SAS HD interface carries a PCIe 3.0 x4 connection, enabling NVMe speeds up to five times faster than a SATA SSD. Actual throughput depends on the SSD and host card, but the cable itself is built for full 4-lane PCIe 3.0 bandwidth.
