weastlinks U.2 SFF-8639 PCIe 3.0 4X Adapter Card

SKU CH-SQG3-7DS78

PCIe 3.0 x4 card adds a U.2 SFF-8639 port for NVMe SSDs on Windows or Linux systems

  • Changer TypeN/A
  • Connects NVME U.2 drives via PCIe 3.0 4X
  • Broad OS support from Windows 7 through 10 and Linux
  • Requires PCIe 4X slot and Windows 10 for full NVME speed
  • Black adapter card weighs 100g
  • Win 7 needs driver but cannot reach NVME performance

PCIe 3.0 4X to U.2 Adapter

This adapter connects a U.2 SFF-8639 NVME SSD to a PCIe 3.0 4X slot. It enables high-speed storage on desktop systems that lack a native U.2 port. The card supports Windows 7, 8, 10 and Linux operating systems. Builders adding fast NVME storage without an M.2 slot will find it useful.

Compatibility and limits

Suits systems with a free PCIe 3.0 4X slot and NVME-aware BIOS or UEFI. Windows 10 is recommended for full speed; Windows 7 requires a driver and cannot reach peak throughput. Boards without NVME protocol support can only use the drive as secondary storage, not as a boot device. Older chipsets such as B85 or Z87 may need a BIOS update and hands-on configuration.

Deciding specification

The PCIe 3.0 4X host interface is the single specification that determines fit. Your motherboard must provide a PCIe 3.0 4X slot and NVME boot support for the SSD to work as intended.

Spørgsmål om denne vare

What motherboard slot is required for the PCIe 3.0 4X interface?

A free PCIe x4 or wider slot (gen 3.0 or newer) provides the four lanes the adapter needs.

Will a B250 chipset board boot from an NVME U.2 drive on this card?

Yes — B250, B150, H170 and Z170 chipsets generally support NVME boot when the BIOS is current.

How do I confirm the drive is running at PCIe 3.0 x4 after installation?

Check the link width and speed in the OS device manager or a tool such as NVMe-cli; it should show x4 and gen 3.0.
