An 80 cm PCIe 5.0 MCIO x8 cable splitting one 74-pin connector into two 68-pin U.2 NVMe ports with integrated power lines

SMUGDESK

SMUGDESK PCIe 5.0 MCIO x8 to Dual U.2 NVMe Adapter 74Pin to 2×68Pin 80CM

SKU CH-55Y5-H7V6E

Converts a PCIe 5.0 MCIO x8 port into two U.2 NVMe connectors with integrated power over an 80 cm cable

  • PCIe 5.0 bandwidth for dual NVMe SSDs
  • Converts one 74Pin MCIO to two 68Pin U.2 ports
  • Built-in power lines deliver stable drive power
  • 80CM Mini Cooledge IO cable enables flexible server wiring
  • Enterprise-grade signal integrity for reliable storage expansion

MCIO x8 to Dual U.2 NVMe Adapter

This PCIe 5.0 adapter converts a single SFF-TA-1016 74Pin MCIO port into two independent SFF-8639 68Pin U.2 ports for NVMe SSD connectivity. It is built for server and workstation storage expansion requiring high bandwidth. The 80CM Mini Cooledge IO cable allows flexible internal routing.

Verify MCIO x8 Port and U.2 Drive Compatibility

Confirm your motherboard or backplane provides an SFF-TA-1016 74Pin MCIO x8 interface before ordering. Ensure the target NVMe SSDs use the SFF-8639 68Pin U.2 form factor. Check that 80CM cable length suits your chassis layout and drive placement.

Integrated Power Lines and Enterprise Build

Built-in power lines deliver stable current directly to both connected drives without separate power cables. Enterprise-grade construction maintains signal integrity across the PCIe 5.0 link for reliable long-term operation. The bundled cable combines data and power in one managed assembly.

Questions about this item

What connectors and cable length come with the SMUGDESK adapter, and do I need to buy any extra cables or power leads?

The box contains one 80-centimetre cable with a 74-pin MCIO plug on one end and two 68-pin U.2 connectors on the other. Power lines are already integrated, so no separate power cable is required.

My motherboard has a single PCIe 5.0 MCIO x8 port — will this adapter let me run two U.2 NVMe drives at full speed?

Yes. The adapter splits one PCIe 5.0 x8 MCIO link into two independent U.2 ports, giving each NVMe SSD a dedicated x4 lane connection at Gen 5.0 bandwidth.

What does the PCIe 5.0 x8 rating mean for real-world throughput when both U.2 slots are populated?

Each drive receives a PCIe 5.0 x4 link, delivering up to 16 GT/s per lane for high-throughput NVMe workloads such as database or content-creation storage.
