SMUGDESK SFF8654 4I to SFF8639 U.2 Adapter Cable 15Pin SATA Power

SKU CH-6K2R-M8N9X

Connects MCIO SlimSAS SFF8654 4I host ports to U.2 SFF8639 NVMe SSDs with integrated 15-pin SATA power

  • Gen5 compliant for high-bandwidth PCIe signal transmission to U.2 NVMe SSD
  • SFF8654 4I MCIO to SFF8639 U.2 direct conversion design
  • Built-in 15-pin SATA power connector supplies stable power for U.2 drives
  • Gold-plated contacts deliver excellent signal integrity in server chassis
  • Braided shielding suppresses EMI interference for enterprise-grade stability

Enterprise storage adapter

This SFF8654 4I to SFF8639 U.2 adapter cable connects MCIO SlimSAS host ports to U.2 NVMe SSD units in enterprise servers, workstations and highperformance storage systems. The integrated 15pin SATA power connector supplies stable auxiliary power for highpowerconsumption drives. It is built for internal chassis deployment where direct hosttoNVMe conversion is required.

Gen5 signal integrity and capacity

Goldplated contacts and highquality twinax conductors maintain PCIe Gen5 signal transmission for U.2 NVMe SSD operation. Braided shielding suppresses EMI interference in dense rackmount environments. The design supports hotswap capable drives for storage expansion and data array building, handling the bandwidth demands of current enterprise NVMe workloads.

Physical interface limits

The cable converts a single SFF8654 4I MCIO port to one SFF8639 U.2 connector, so each adapter serves one NVMe drive. Builders who need multiple U.2 devices must provision one MCIO port and one adapter per drive. The fixed cable length and connector orientation determine routing options inside the chassis.

Questions about this item

Will the SFF8654 4I end connect to my existing MCIO SlimSAS host port?

Yes, the SFF8654 4I MCIO connector is designed for direct insertion into a compatible MCIO SlimSAS host port, providing a secure mating interface for enterprise server or workstation chassis.

How can I verify the adapter is delivering a stable Gen5 PCIe link to my U.2 NVMe SSD?

After installation, confirm the drive appears at PCIe Gen5 speeds in the system BIOS or operating system device manager and run a sustained I/O workload to check for errors or throttling.

Does the package include the 15-pin SATA power lead or must I source it separately?

The 15-pin SATA power connector is integrated into the cable assembly, so no separate power cable purchase is required for the U.2 drive.
