SMUGDESK PCIe 4.0 M.2 to U.2 NVMe Adapter SFF-8639 with 75cm Power Cable

M.2 to U.2 NVMe adapter for PCIe 4.0 systems

This SMUGDESK adapter connects an SFF-8639 U.2 NVMe solid-state drive to an M.2 host slot. It serves desktop, workstation and server builders who need to use enterprise or high-capacity U.2 drives on a motherboard that only provides an M.2 interface.

PCIe 4.0 speed limited by host slot and drive

The adapter follows the PCIe 4.0 specification, so its maximum throughput matches the slower of the host M.2 slot and the attached U.2 NVMe drive. If either side operates at PCIe 3.0, the link will run at that lower generation without any configuration required.

Bidirectional M.2 host to SFF-8639 U.2 conversion

The board converts in both directions, letting an M.2 host drive a U.2 SSD or a U.2 host accept an M.2 NVMe module. A 75cm power cable is included to supply the drive, and the unit works plug-and-play without driver installation.
