SMUGDESK PCIe 5.0 x16 to Dual MCIO 8i Splitter Card with 50cm Cable

SKU CH-6T0N-NEGYH

Splits one PCIe 5.0 x16 slot into two MCIO 8i x8 ports with a 50 cm cable for eGPU or NVMe expansion

  • Splits one PCIe 5.0 x16 slot into two MCIO 8i x8 ports
  • Full Gen5 bandwidth with backward compatibility to PCIe 4.0 and 3.0
  • Includes 50cm MCIO cable for flexible external wiring
  • Supports external GPU and high-speed NVMe storage expansion
  • Stable circuit design for continuous operation under Windows and Linux

Splitter Card Overview

The SMUGDESK PCIe 5.0 x16 to Dual MCIO 8i Splitter Card converts a single PCIe 5.0 x16 slot into two independent MCIO 8i x8 ports. It is designed for users adding an external GPU or high-speed NVMe storage to a workstation or server. The card maintains full Gen5 speed and is backward compatible with PCIe 4.0 and 3.0. A 50cm MCIO cable is included for flexible external wiring.

Compatibility Check

Verify that your motherboard has a free PCIe x16 slot capable of bifurcation to support dual x8 operation. Confirm your chassis has space for the card and the 50cm cable routing to the external device. Ensure your target external GPU enclosure or NVMe storage subsystem uses MCIO 8i connectors. The card operates under Windows and Linux without proprietary drivers.

Build Integration

The card installs directly into a PCIe x16 slot and splits the 16 lanes into two x8 links for separate devices. This frees internal drive bays by moving NVMe storage or GPU compute outside the main chassis. The included 50cm cable provides reach for external enclosures while maintaining signal integrity. Stable circuit design supports continuous operation in high-end PC and server environments.

Questions about this item

Does the card include both MCIO cables or do I need to buy a second one separately?

The package provides one 50cm MCIO cable for a single MCIO 8i port; a second cable must be purchased if you want to use both ports.

When should I choose this dual MCIO 8i splitter over a single-port adapter?

Choose this splitter when you need two independent x8 links from one PCIe 5.0 x16 slot — for example to connect two external GPU enclosures or two NVMe storage arrays simultaneously.

What bandwidth does each MCIO 8i port deliver in a PCIe 5.0 system?

Each MCIO 8i port runs at full PCIe 5.0 x8 speed, giving 16 GT/s per lane with no bandwidth loss thanks to the full-speed base design.
