PCIe 5.0 x16 to Dual MCIO 8i Adapter
This PCIe 5.0 adapter converts a single x16 slot into two SFF-TA-1016 74Pin MCIO 8i female ports, each running at x8 bandwidth. It targets workstation and server builders who need high-speed external GPU or NVMe expansion from a standard full-height bracket. Compatible with Windows, Linux and VMware environments for flexible deployment.
Dedicated 6Pin Power for External GPU
The onboard 6Pin GPU power input delivers stable auxiliary power to high-consumption external graphics cards, removing reliance on slot power alone. This ensures reliable operation when driving demanding eGPU enclosures or dense storage arrays through the dual MCIO channels. Full PCIe 5.0 32GT/s throughput is maintained across both ports.
Verify Slot, Cabling and OS Support
Confirm your motherboard provides a physical PCIe 5.0 x16 slot with electrical x16 wiring; bifurcation support is required to split the lane into two x8 links. Ensure you have compatible MCIO 8i cables (SFF-TA-1016) for the target enclosures and that your operating system recognises PCIe 5.0 speeds. Buyers needing a single-port solution or lacking a 6Pin power supply connector should consider other options.

Questions about this item
Does the 6-pin power connector on the adapter ever need replacement?
The 6-pin GPU power input is a standard PCIe connector rated for the card's lifetime; no periodic replacement is scheduled.
What limits sustained throughput on each MCIO 8i channel?
Each channel is electrically x8 at PCIe 5.0 32 GT/s, so the lane count and signal rate set the ceiling.
How much heat does the card add when it runs all day?
The adapter has no active cooling; it relies on case airflow and its optimized PCB layout to manage heat during continuous operation.
