SFF-8643 to U.2 SFF-8639 NVMe Adapter Cable 80cm

This 80cm adapter cable converts an SFF-8643 interface to a U.2 SFF-8639 port for connecting U.2 NVMe SSDs. Gold-plated contacts and durable cable material reduce signal loss and interference during high-speed NVMe transmission. The flexible length allows practical routing inside server and desktop chassis. It provides a plug-and-play connection for storage upgrades.

Suits installers adding U.2 NVMe drives

The adapter serves technicians upgrading enterprise servers, storage arrays or NAS units where an SFF-8643 connector is present. Builders needing a different connector type, a shorter reach or an internal drive bay mount will not find those requirements met by this cable. It addresses only the specific SFF-8643 to U.2 SFF-8639 conversion.

80cm length for chassis routing

The 80cm dimension determines whether the cable reaches from the host connector to the U.2 drive location in a given chassis. Measure the internal path before purchase; a shorter or longer run requires a different cable length. This single physical constraint decides if the part fits the build.

Questions about this item

What connectors are on the cable and does it include a U.2 NVMe SSD?

The cable has an SFF-8643 plug on one end and a U.2 SFF-8639 receptacle on the other. No SSD is included; it must be purchased separately.

How do I choose the correct version of this SFF-8643 to U.2 adapter?

This is a single 80cm model that converts SFF-8643 to U.2 SFF-8639 for NVMe SSDs. No other versions or capacities are offered.

What does the 80cm length mean when routing the cable inside a server chassis?

The 80cm length gives enough slack to route from a backplane or controller card to a U.2 drive bay while keeping cables tidy in dense builds.
