SMUGDESK

SMUGDESK PCIe 5.0 MCIO 8i 74Pin to Dual SFF8639 Cable with 15Pin Power, 1M

SKU CH-CB3X-GQ5K6

Converts a single PCIe 5.0 MCIO 8i 74Pin port into two SFF8639 U.2 NVMe connections with integrated 15Pin power delivery at 32Gbps bandwidth

  • PCIe 5.0 compliant cable enables 32Gbps NVMe SSD expansion
  • 74Pin MCIO 8i port splits to dual SFF8639 U.2 connectors
  • Integrated 15pin power connectors combine data and power delivery
  • 32AWG pure copper wire minimizes signal loss for stable performance
  • 1meter length supports tidy routing in standard rackmount servers

PCIe 5.0 MCIO to dual U.2 breakout

This PCIe 5.0 cable converts a single MCIO 8i 74Pin port into two SFF8639 U.2 interfaces for NVMe SSD expansion. Integrated 15pin power connectors combine data and power delivery in one assembly. The 1meter length suits standard rackmount servers and highperformance workstations. It targets builders adding highdensity U.2 storage to compatible backplanes.

Sustained 32Gbps bandwidth for enterprise workloads

The cable supports 32Gbps transfer rates across both U.2 links for continuous enterprise SSD traffic. 32AWG lowloss pure copper conductors minimise signal attenuation and crosstalk during prolonged heavy I/O. This construction maintains link stability for AI compute nodes and missioncritical storage arrays. It is not suited for connections requiring longer reach than one metre.

Thermals noise and power delivery

Passive copper construction adds no active cooling noise to the chassis. The integrated 15pin power lines deliver stable current to both U.2 drives without separate power cables. Reduced connector count improves airflow in dense server layouts. The design assumes the host backplane and drives manage their own thermal limits.

Questions about this item

How much heat or power does the 32Gbps MCIO 8i cable draw during continuous operation?

The cable itself is passive and draws no power; only the attached U.2 SSDs consume power delivered through the 15pin connectors.

What host connector must my motherboard or controller provide for this 74Pin MCIO 8i breakout cable?

A single PCIe 5.0 Slimline MCIO 8i 74Pin port is required to plug the cable into the system.

Will the SFF8639 ends work with my older SAS SSDs as well as NVMe U.2 drives?

The SFF8639 connectors are wired for NVMe U.2 SSDs; SAS protocol is not supported by this breakout cable.
