Fervit MCIO 4x to U.2 SFF-8639 NVMe PCIe 5.0 Cable 50cm

SKU CH-2T7T-ZQ0M5

A 50 cm cable that adds an MCIO 4x connection for a U.2 SFF-8639 NVME drive with PCIe 5.0, 4.0 and 3.0 x4 support

  • 50cm length for flexible internal routing
  • Supports PCIe 5.0, 4.0 and 3.0 x4 speeds
  • MCIO 4x to U.2 SFF-8639 NVMe connectivity
  • Adds one MCIO interface for SSD expansion
  • Compatible with Intel SSD 750 M.2 and MCIO 4x setups

MCIO 4x to U.2 NVMe cable

This 50 cm cable connects a motherboard MCIO 4x port to a U.2 SFF-8639 NVMe drive. It adds one MCIO interface so a single SSD can be attached using an optional adapter. The cable is sold alone without an adapter card. It suits builders adding high-speed storage to compatible server or workstation boards.

PCIe 5.0 x4 signal limit

The link supports PCIe 5.0, 4.0 and 3.0 at x4 lane width. Bandwidth is capped by the x4 electrical interface and the 50 cm trace length. Signal integrity meets the PCIe 5.0 spec at this distance. No retimer or active components are present on the cable itself.

U.2 drive capacity headroom

One U.2 NVMe SSD up to the PCIe 5.0 x4 ceiling can be driven. The cable handles current enterprise capacities including 750 GB class drives. It cannot serve multiple drives or split the MCIO port into additional endpoints. Builders needing more than one U.2 device require a separate MCIO port or splitter.

Questions about this item

How do I choose the right cable length for my MCIO 4x to U.2 NVMe setup?

This cable is 50 cm long and includes only the cable; the adapter card is not included, so select it if that length fits your chassis routing.

What does PCIe 5.0 x4 support mean for an NVMe SSD connected through this cable?

It allows the SSD to run at PCIe 5.0, 4.0 or 3.0 x4 speeds, matching the drive and motherboard capability.

What interface standard does the SFF-8639 connector use and what does it cap in practice?

The SFF-8639 U.2 connector carries NVMe over PCIe 5.0 x4, so the practical ceiling is the PCIe 5.0 x4 bandwidth.
