MCIO 4X to U.2 NVMe PCIe Cable
This 50cm cable connects a mainboard MCIO 4X port to a U.2 SFF-8639 NVMe SSD. It transmits PCIe signals using the 4x protocol and supports PCIe 5.0, 4.0 and 3.0 x4. The cable is designed for high-performance networking and server equipment.
Suits builders adding U.2 storage via MCIO
The cable works with Intel SSD 750 M.2 and MCIO 4x configurations. It supports SAS 3.0 and 4.0 alongside 25G Ethernet and 56GT/s PAM4 signalling. Builders who need an included adapter card or a different cable length should look elsewhere.
Single specification that decides fit
The MCIO 4X to U.2 SFF-8639 connector pairing determines compatibility. Your mainboard must provide an MCIO 4X interface and your drive must use the U.2 SFF-8639 form factor. Without this exact match the cable cannot function.

Questions about this item
What motherboard connector is required for the MCIO 4X end of this cable?
The cable needs a motherboard or controller with an MCIO 4X port that carries PCIe 5.0/4.0/3.0 x4 signals.
Can I attach a legacy U.2 drive that only supports PCIe Gen 3 to this cable?
Yes, the cable transmits PCIe x4 and is backward compatible with PCIe 3.0, 4.0 and 5.0 devices.
How do I verify the link is running at PCIe 5.0 x4 after connecting an NVME SSD?
Check the negotiated link speed and width in the OS device manager or with a tool such as lspci -vv.
