SMUGDESK PCIe 5.0 x16 to Dual MCIO 8i Splitter Kit with 2×50CM Cables
Splits a PCIe 5.0 x16 slot into two MCIO 8i x8 channels with two 50 cm cables for eGPU or NVMe expansion
- Splits one x16 slot into two MCIO 8i x8 channels
- Full-speed base keeps full bandwidth without lane loss
- Kit includes two 50CM MCIO cables for dual devices
- Optimized PCB layout stable under Windows, Linux, VMware
- Downward compatible with PCIe 4.0 and 3.0
Splitter Kit Purpose
This SMUGDESK kit converts a single PCIe 5.0 x16 slot into two independent MCIO 8i x8 channels. It targets workstation and server builders who need external GPU docking or high-speed NVMe storage arrays without sacrificing lane bandwidth. The included 50CM cables allow separate device connections.
Setup Verification
Confirm the host system provides a physical PCIe x16 slot wired for at least x16 electrical lanes. Ensure the operating environment runs Windows, Linux or VMware for validated long-hour stability. Verify that each target MCIO device accepts an 8i interface and matches the required protocol generation.
Build Integration
The card occupies one x16 slot and delivers two MCIO 8i ports for direct cabling to external enclosures or drive backplanes. Downward compatibility with PCIe 4.0 and 3.0 lets the kit function in older platforms at reduced speeds. It frees internal drive bays by moving high-throughput storage or GPU resources outside the chassis.

Questions about this item
What cables and adapters are included in the kit?
The kit includes the PCIe 5.0 x16 to dual MCIO 8i splitter card and two 50CM MCIO cables for connecting two separate MCIO devices.
Should I choose this splitter for a PCIe 4.0 motherboard or only for 5.0?
It is downward compatible with PCIe 4.0 and 3.0, so it works on older platforms while keeping the x8 per channel layout.
Will an x16 GPU run at full x16 speed through one of the MCIO 8i ports?
Each port provides an x8 electrical link, so a single GPU would operate at x8 bandwidth rather than the full x16.
