Vszerda U.2 SFF-8639 to M.2 SFF-8643 Cable

This 50 cm internal cable connects a U.2 NVME SSD using an SFF-8639 interface to a mainboard or controller equipped with an M.2 SFF-8643 Mini SAS HD port. It supports PCIe 3.0 x4 signalling for 4 GBps throughput. The cable is sold alone without any adapter or add-in card included.

Builders linking U.2 drives to SFF-8643 ports

Suits system integrators adding enterprise U.2 storage to a workstation or server board that exposes an SFF-8643 connector. Not for users who need a complete kit with a mounting bracket or PCIe adapter card, nor for connections that require a different port type or longer reach than 50 cm.

PCIe 3.0 x4 at 4 GBps over SFF-8639 to SFF-8643

The link width and protocol determine whether the SSD can run at its rated speed; this cable carries four PCIe 3.0 lanes end-to-end. Verify that the host port is wired for PCIe and not solely for SAS, and confirm the 50 cm length fits your chassis routing before purchase.

Questions about this item

Does the SFF-8639 to SFF-8643 cable generate noticeable heat during continuous PCIe 3.0 x4 transfers?

The passive 50 cm cable carries PCIe 3.0 x4 signals without active components, so it adds negligible heat to the chassis airflow.

Which controller or mainboard port must I already have to connect a U.2 NVME drive with this SFF-8639 cable?

You need a mainboard or controller with an M.2 SFF-8643 Mini SAS HD receptacle that supports PCIe 3.0 x4.

Will the 50 cm link run at PCIe 3.0 x4 speeds with an older SSD 750 that uses the SFF-8639 interface?

Yes, the cable is rated for PCIe 3.0 x4 and 4 GBps, matching the SSD 750 U.2 SFF-8639 specification.
