SMUGDESK SFF-8654 8i 74-pin to Dual SFF-8639 U.2 + 15-pin Cable .8m

SKU CH-PP96-XXR11

Splits one SFF-8654 8i 74-pin port into two SFF-8639 U.2 connectors with 15-pin power using 32AWG copper at .8m

  • Low-profile design fits space-restricted servers and workstations
  • One-to-two breakout converts single SFF-8654 8i port to dual U.2 SFF-8639 ports with 15-pin power
  • 32AWG low-loss copper wire ensures stable high-bandwidth transmission for NVMe SSDs
  • 8m optimized length enables neat internal routing for server storage builds
  • Precision-shielded construction minimizes signal loss and crosstalk for datacentre-grade reliability

Low-profile SFF-8654 breakout cable

This low-profile SFF-8654 8i 74-pin cable splits one SlimSAS port into two SFF-8639 U.2 connectors with integrated 15-pin power delivery. The slim form factor fits space-restricted compact servers and high-density workstation chassis. It targets builders adding NVMe storage where internal clearance is tight.

Practical limits of the SAS interface

The 32AWG pure copper conductors and precision shielding minimise signal loss and crosstalk for stable high-bandwidth transmission. The .8 metre length is optimised for neat internal routing inside modern server storage builds. Bandwidth and drive support depend on the host controller and backplane specifications.

Check your existing setup before ordering

Verify the host provides a single SFF-8654 8i port and that the target U.2 drives accept 15-pin power from the cable. Confirm the chassis can accommodate the .8 metre reach between the controller and drive bays. This cable does not suit builds needing longer runs or different connector pinouts.

Highlights

  • Low-profile design fits space-restricted servers and workstations

  • 32AWG low-loss copper wire ensures stable high-bandwidth transmission for NVMe SSDs
  • 8m optimized length enables neat internal routing for server storage builds
  • Precision-shielded construction minimizes signal loss and crosstalk for datacentre-grade reliability

Questions about this item

How do I decide between a single U.2 cable and this dual breakout version?

The dual breakout turns one SFF-8654 8i port into two independent SFF-8639 U.2 connections, so you can attach two NVMe SSDs instead of one without using extra controller ports.

What real-world bandwidth can I expect from the .8 m cable inside a server?

The 32 AWG pure copper conductors and heavy shielding keep signal loss low, letting each U.2 lane run at full SAS speed for enterprise NVMe drives.

Does the SFF-8654 8i interface cap the throughput of the two U.2 ports?

The SFF-8654 8i 74-pin connector carries eight lanes, providing four lanes to each SFF-8639 U.2 port so neither drive is bottlenecked by the host link.
