Low-profile SFF-8654 74-pin cable splitting to dual SFF-8639 U.2 connectors with 15-pin power, 0.5 m length

SMUGDESK

SMUGDESK LP SFF8654 8i 74Pin to Dual SFF8639 U.2 + 15Pin Cable .5M

SKU CH-TH1T-BXCXR

Connects one SFF8654 8i 74pin port to two SFF8639 U.2 drives with integrated 15pin power using 32AWG shielded copper for stable NVMe signal transmission in tight server bays

  • Slim LP design fits tight server enclosures
  • One SFF8654 8i 74pin splits to dual SFF8639 U.2 with 15pin power
  • 32AWG copper conductors deliver low-loss highspeed NVMe signals
  • 5M length keeps internal wiring clean in dense backplanes
  • Heavy shielding cuts crosstalk for reliable U.2 SSD operation

Low-Profile SFF-8654 8i to Dual U.2 Cable

This low-profile server interconnect cable adapts a single SFF-8654 8i 74-pin host port to two SFF-8639 U.2 connectors with integrated 15-pin power delivery. The slim LP form factor fits compact, space-constrained enclosures. Built with 32AWG copper conductors and heavy-duty shielding, it ensures stable high-speed signal transmission for U.2 NVMe SSDs in dense storage nodes and rackmount servers.

Suits Dense NVMe Backplanes; Not for Longer Runs

The 0.5M length is optimised for neat internal routing within high-density NVMe storage backplanes and compact chassis. Builders deploying U.2 drives in tight 1U or 2U servers benefit from the short reach and low-profile connector. Buyers who need a longer run for full-height chassis or external JBOD connections should look at alternative cable assemblies.

Host Connector Is SFF-8654 8i 74-Pin

The decisive specification is the SFF-8654 8i 74-pin host interface, which must match the controller or backplane port exactly. This cable splits that single port into dual SFF-8639 U.2 targets with 15-pin power. Verify your host side uses SFF-8654 8i before purchasing; other host connector types are not compatible with this assembly.

Questions about this item

Which controller port does the SFF-8654 8i 74-pin end plug into?

It connects to a single SFF-8654 8i 74-pin port on a SAS controller or backplane that supports NVMe drives.

Can I keep my existing U.2 NVMe SSDs when adding this cable?

Yes, the dual SFF-8639 U.2 connectors accept standard U.2 NVMe SSDs and supply 15-pin power to each drive.

How do I verify the link is healthy after installation?

The drives should appear in the OS and BIOS, and SMART data should report a clean NVMe link without errors.
