Low-profile SFF-8654 74-pin cable splitting to dual SFF-8639 U.2 with 15-pin power connectors

SMUGDESK

SMUGDESK LP SFF8654 8i 74Pin to Dual SFF8639 U.2 + 15Pin Power InfiniBand Cable

SKU CH-X3TJ-E1XRS

Low-profile cable splits one SFF-8654 8i port into two SFF-8639 U.2 NVMe connectors with integrated 15-pin power using 32AWG copper

  • Low-profile design fits slim server chassis
  • Single 74-pin port splits to dual U.2 drives with 15-pin power
  • 32AWG copper ensures stable NVMe bandwidth
  • Combined data and power reduces internal cable clutter
  • One-metre length suits standard low-profile storage builds

Low-profile SFF-8654 breakout cable

This low-profile cable converts a single SFF-8654 8i 74-pin SlimSAS port into two independent SFF-8639 U.2 connectors with integrated 15-pin power. It is built for administrators deploying U.2 NVMe SSDs inside slim server or workstation chassis where vertical clearance is restricted. The 1-meter length suits standard low-profile storage expansion and RAID builds.

Installing the breakout cable

The LP form factor slips into tight backplanes without blocking adjacent slots, and the all-in-one data-plus-power design removes the need for separate power leads. Route the 32AWG copper conductors carefully to avoid sharp bends that could degrade signal integrity. Verify that the host controller supports bifurcation so both U.2 ports appear as independent devices.

Sustained workload behaviour

Premium 32AWG copper conductors and server-grade shielding maintain stable high-bandwidth transmission during continuous NVMe traffic. The integrated 15-pin power delivery keeps each SSD fed without voltage droop under heavy write cycles. This construction supports reliable operation in RAID arrays and high-performance storage workloads that run for extended periods.

Highlights

  • Low-profile design fits slim server chassis
  • Single 74-pin port splits to dual U.2 drives with 15-pin power
  • 32AWG copper ensures stable NVMe bandwidth
  • Combined data and power reduces internal cable clutter
  • One-metre length suits standard low-profile storage builds

Questions about this item

How can I confirm the LP SFF8654 cable is transmitting data correctly to both U.2 NVMe SSDs after installation?

The drives should appear in the RAID controller BIOS and operating system without errors, and sustained read or write tests should complete at expected NVMe speeds.

What connectors and accessories are included with the SFF8654 74pin to dual SFF8639 cable, and what must I source separately?

The cable provides one SFF8654 8i 74pin plug, two SFF8639 U.2 receptacles and integrated 15pin power connectors; you must supply the U.2 NVMe SSDs and a compatible SlimSAS host port.

Which version of this lowprofile interconnect should I choose for a 1meter run inside a slim server chassis?

Select the 1meter LP SFF8654 8i to dual SFF8639 U.2 cable with 32AWG copper conductors and integrated 15pin power for spaceconstrained server storage expansion.
