PCIe 5.0 x16 to Dual MCIO 8i Splitter
This adapter card splits a single PCIe 5.0 x16 slot into two independent MCIO 8i x8 ports. It is built for workstation users and server builders who need to route high-speed lanes outside the chassis. The board maintains full lane performance without bandwidth loss. It suits external GPU docking and high-speed NVMe storage expansion.
Upgrade from PCIe 4.0 or 3.0 platforms
The card is backward compatible with PCIe 4.0 and 3.0 systems, so it can replace older splitter cards that limit lane speed. The jump is worth it when your workload demands the full 5.0 signalling rate across both ports. If your current host only runs at 4.0 or 3.0, the adapter will still function at that generation's speed. Buyers who need more than two MCIO connections should look elsewhere.
Fits servers and high-end desktops
A 50 cm MCIO cable is included for flexible external wiring layout. The design frees up internal space by moving GPU or storage links outside the case. It works with mainstream Windows and Linux operating systems without extra drivers. Builders who lack a PCIe x16 slot cannot use this card.

Questions about this item
Does the PCIe 5.0 x16 card require a specific slot size or bracket height to fit in a server chassis?
The card uses a standard PCIe 5.0 x16 slot and splits into dual MCIO 8i ports for external GPU or NVMe expansion.
How is the 50cm MCIO cable connected during installation, and what is the common mistake?
Insert the card into the x16 slot, then attach the MCIO cable to both 8i ports; the frequent error is reversing the cable orientation on the port latch.
What maintenance does the splitter card and included 50cm cable need over time?
Reseat the MCIO connectors and inspect the cable for kinks every few months to maintain PCIe 5.0 signal integrity.
