Connection Purpose

This MCIO 4x to SFF-8639 cable links a motherboard MCIO slot to a U.2 NVME drive, adding one PCIe 5.0 x4 connection for internal storage expansion. It targets server and workstation builders who need a direct high-speed link without an extra adapter card. The 50 cm length suits typical chassis routing.

Bundled Items

The package contains only the shielded cable; no adapter, bracket or drive is included. Users must source a compatible U.2 device and ensure their board exposes an MCIO 4i connector. Correct insertion orientation is required to avoid damage, and the assembly does not support hot-plugging.

Interface Limits

The link carries PCI Express signals at up to PCIe 5.0 x4 speeds and is backward compatible with 4.0 and 3.0. It does not carry SAS traffic, so SAS RAID controllers cannot be used with this cable. Shielding is rated for high-speed PCIe 4.0 operation.

Questions about this item

Does the MCIO 4x connector require periodic cleaning or scheduled replacement?

No scheduled cleaning or replacement is required for the MCIO 4x connector under normal use.

What is the first limit reached when the cable runs at PCIe 5.0 x4 continuously?

The 50 cm length and PCIe 5.0 signaling define the practical limit for sustained full-speed operation.

How much heat does the cable generate during all-day PCIe 5.0 x4 transfers?

The passive cable produces negligible heat; any warmth comes from the connected SSD or controller, not the cable itself.
