SFF-8643 to U.2 SFF-8639 Cable .5m
This cable connects a host SFF-8643 port to a U.2 SFF-8639 NVMe SSD. It includes a 15-pin SATA power connector to supply the drive. The link supports data rates up to 4GB/s over PCI Express 3.0. The assembly measures .5 metres and ships in black.
Suitable Builds and Limits
The part suits integrators adding U.2 NVMe storage to a backplane or HBA with an SFF-8643 interface. It will not work for builders who need a longer reach between controller and drive. It also does not suit systems that lack a SATA power header for the 15-pin plug.
Deciding Specification
The critical detail is the SFF-8643 host interface paired with a U.2 SFF-8639 device connector and integrated 15-pin SATA power. Only controllers and drives matching those exact ports can use this cable.

Questions about this item
Does the host side need a free SFF-8643 port on my RAID card or motherboard?
Yes, the cable plugs into an SFF-8643 host connector, so the system must provide that port.
Can I keep using an older NVMe U.2 drive that only supports PCIe 2.0?
The cable carries PCIe 3.0 signals up to 4 GB/s and will fall back to the drive's native speed.
How can I confirm the 15-pin SATA power connector is delivering power to the drive?
The drive should appear in the BIOS or OS device list once the SATA power lead is seated and the system is on.
