The MCIO 8X to 2x U.2 cable VTC-AMSE70010001-K2 from VITALCONN is a dedicated PCIe Gen 4 server cable that converts a single MCIO 8X (8-lane) host connector into two U.2 (SFF-8639) storage interfaces. An integrated 15-pin power connector is bundled into the same assembly, so both data and power reach the attached U.2 devices through one managed harness. The MCIO 8X to 2x U.2 cable is widely used in data center servers, storage enclosures, and high-performance computing platforms where MCIO-based motherboards must drive direct-attach NVMe storage with clean, simplified cabling.

Built on 30 AWG high-frequency twin-axial conductors with an 85 ohm controlled differential impedance, the MCIO 8X to 2x U.2 cable preserves signal integrity across the full split, supporting PCIe Gen 4 data rates of 16 GT/s per lane. Shielded differential pairs and a robust overall screen minimize crosstalk and electromagnetic interference, while strain-relief molding protects the bifurcation point in high-vibration server environments. Combining the compact MCIO host interface with industry-standard U.2 device connectors gives system integrators a flexible, space-saving alternative to discrete riser cards and legacy cabling.

VITALCONN supplies the MCIO 8X to 2x U.2 cable in multiple standard lengths, with OEM/ODM custom lengths, labels, and packaging available on request. Every cable is inspected for impedance continuity and workmanship before shipment. For interface definitions, consult the official SFF Committee standards covering SFF-8639 and MCIO (SFF-TA-1016 style) connectors, and explore the complete High Speed Cable portfolio at VITALCONN for all your server interconnect needs.

Frequently Asked Questions

What PCIe generation does the MCIO 8X to 2x U.2 cable support?

The MCIO 8X to 2x U.2 cable is designed for PCIe Gen 4 platforms, supporting 16 GT/s per lane, and provides a reliable data path between MCIO host ports and U.2 (SFF-8639) NVMe storage devices.

What is the purpose of the 15-pin power connector?

The 15-pin power connector supplies power directly to the attached U.2 devices. By combining data and power in one cable assembly, it eliminates separate power runs and simplifies internal cable management.

Can I order custom cable lengths for my chassis?

Yes. VITALCONN offers OEM/ODM custom lengths, labels, and packaging tailored to your server or storage enclosure. Contact us with your required length and quantity for a quotation.

How does this cable simplify server cabling?

Instead of routing a discrete data cable and a separate power harness to each U.2 drive, the MCIO 8X to 2x U.2 cable integrates both functions in a single assembly, reducing clutter and improving airflow.
