eshinreal 2-Port MCIO to PCIe 5.0 x16 Adapter Card

SKU CH-98GR-QPWVP

Converts a PCIe 5.0 x16 slot into two MCIO ports for NVMe SSDs, GPUs or NICs at 64 GT/s bandwidth

  • Product typeController Card
  • PCIe 5.0 bandwidth up to 64 GT/s for ultra-fast data transfer
  • Dual MCIO ports turn one x16 slot into two high-speed connections
  • Supports NVMe SSDs, GPUs or NICs for flexible server expansion
  • Low-latency design keeps AI and HPC workloads running smoothly
  • Plug-and-play compatibility simplifies deployment in workstations and servers

Dual MCIO Expansion

This adapter converts a single PCIe 5.0 x16 slot into two MCIO ports for high-speed connectivity. It targets server and workstation builders who need to add NVMe storage, GPUs, or network cards without occupying additional full-length slots. The design suits AI, HPC, and all-flash array deployments requiring dense I/O expansion.

Thermals and Power

The card operates as a passive signal bridge with no active cooling or onboard controller logic. It draws negligible power from the host slot while maintaining signal integrity at 64 GT/s. No fans or heatsinks are required, keeping acoustic output at zero during normal operation.

Build Integration

Installation requires a free PCIe 5.0 x16 slot and compatible MCIO cables to reach target devices. The bracket occupies a single rear expansion slot, leaving adjacent slots clear for other add-in cards. It enables dense storage or accelerator configurations where physical space limits the number of full-height cards.

Questions about this item

How do I install this adapter into a PCIe 5.0 x16 slot, and what step is often missed?

Align the card with the PCIe 5.0 x16 slot, press firmly until the retention bracket clicks, then secure the bracket screw to the chassis; the step often missed is fastening that screw, which prevents the card from lifting under cable tension.

What maintenance or replacement will this adapter need over time?

No scheduled maintenance is required; if a future component change demands a different port layout, the card itself would be replaced rather than serviced.

What limit appears first when this adapter runs sustained workloads?

The PCIe 5.0 x16 link caps bandwidth at 64 GT/s, so sustained throughput cannot exceed that link ceiling regardless of the attached devices.
