PCIe 5.0 X4 to U.2 Adapter

This SMUGDESK adapter card converts a PCIe 5.0 X4 slot into a U.2 SFF8639 port for NVMe SSDs. It supports up to 128Gbps bandwidth for high-speed data transfer. The design focuses on stable signal transmission for demanding workloads. Installation is plug-and-play for quick storage upgrades.

Suits enterprise NVMe SSD expansion.

This card targets users adding U.2 enterprise NVMe SSDs to servers, workstations or high-end PCs. It fits builds needing high-capacity storage and heavy-duty data performance. Buyers whose drives use a different physical connector or protocol should look at other adapter types. The PCIe 5.0 interface requires a compatible motherboard slot to function.

PCIe 5.0 X4 interface with 128Gbps bandwidth

The single specification that decides compatibility is the PCIe 5.0 X4 interface delivering up to 128Gbps throughput. Your motherboard must provide a PCIe 5.0 X4 slot to reach this speed. The U.2 SFF8639 port accepts mainstream enterprise NVMe SSDs. Verify your drive and board match these exact interface requirements.

Questions about this item

What comes in the box and do I need to buy any cables or brackets separately?

The adapter card itself is supplied; any U.2 cable or mounting bracket required for your chassis must be purchased separately.

Which PCIe generation and lane width should my motherboard provide for the 128Gbps link?

A PCIe 5.0 X4 slot is needed to reach the 128Gbps bandwidth.

What real-world throughput can I expect from the 128Gbps figure once the card is installed?

The 128Gbps represents the theoretical PCIe 5.0 X4 ceiling; actual NVMe SSD speeds depend on the drive and workload.
