SMUGDESK PCIe 5.0 x16 to Dual MCIO 8i SFF-TA-1016 74Pin Female Expansion Card

SKU CH-REHM-W67R9

Converts a single PCIe 5.0 x16 slot into two SFF-TA-1016 MCIO 8i female ports with 74 pins each for NVMe SSD arrays or external GPU expansion

  • Converts one PCIe 5.0 x16 slot into two SFF-TA-1016 MCIO 8i ports
  • Full 32GT/s Gen5 bandwidth, backward compatible with PCIe 4.0 and 3.0
  • Mini Cool Edge IO interface for NVMe SSD array and external eGPU
  • Optimized PCB layout ensures stable high-speed signal for long-running server use
  • Standard full-height bracket works with Windows, Linux and VMware systems

PCIe 5.0 x16 to Dual MCIO 8i Adapter

This adapter converts a single PCIe 5.0 x16 slot into two SFF-TA-1016 MCIO 8i female connectors. Each 74-pin port operates at x8 electrical width, supporting full Gen5 32GT/s bandwidth for high-speed data transfer. It is designed for server and workstation builders expanding NVMe storage arrays or adding external GPU connectivity.

Suits high-density storage and eGPU projects

Builders assembling high-end storage servers or external GPU enclosures using the Mini Cool Edge IO standard will find the dual-port layout and backward compatibility with PCIe 4.0 and 3.0 useful. Systems limited to fewer PCIe lanes or lacking a full-height x16 slot cannot use this card.

Single x16 slot splits into two x8 MCIO 8i ports

The decisive specification is the conversion of one physical x16 slot into two independent x8 channels via SFF-TA-1016 connectors. Verify that the host platform bifurcates the x16 link and that the target devices use the 74-pin MCIO 8i interface before purchasing.

Questions about this item

How much heat does the PCIe 5.0 x16 to dual MCIO 8i card generate under continuous server workloads?

The card uses an optimized PCB for stable high-speed signal integrity during long-running operation, and as a passive adapter it adds no active cooling requirement of its own.

What existing hardware is required to use the two SFF-TA-1016 74Pin female ports?

You need a motherboard with a free PCIe 5.0 x16 slot (backward compatible with 4.0 and 3.0), MCIO 8i cables, and target NVMe drives or an eGPU enclosure that accept the SFF-TA-1016 interface.

Will this adapter work with older PCIe 3.0 NVMe drives I already own?

Yes, the card is backward compatible with PCIe 3.0 and 4.0, so existing NVMe SSDs will operate at their native speeds when connected through the dual MCIO 8i ports.
