SlimSAS SFF-8654 8i Adapter Cable

This 1 metre cable connects an SFF-8654 8i SlimSAS host port to two U.2 SFF-8639 NVMe SSDs. It delivers PCIe 4.0 x8 bandwidth up to 64Gbps total across both drives. A 15-pin SATA power connector supplies stable power to the SSDs without requiring an external PCIe power source. Silver-plated AWG30 Twinax conductors with 85 ohm impedance maintain signal integrity for PCIe 4.0 reliability.

Server And NAS Storage Expansion

Suited for rack servers, NAS units and HPC clusters adding dense U.2 NVMe storage such as Intel Optane, Samsung PM1735 or Micron 9300 series drives. Works with PCIe 4.0 and 3.0 motherboards or backplanes that do not require bifurcation. Builders needing to attach M.2 form-factor drives or SATA SSDs should select a different adapter cable.

PCIe 4.0 X8 Bandwidth Support

The cable carries PCIe 4.0 x8 electrical signals split across two U.2 ports for up to 64Gbps aggregate throughput. This single specification determines whether the host controller and SSDs can operate at their rated PCIe 4.0 speeds through this interconnect.

Questions about this item

Will the SFF-8654 8i cable run two U.2 NVMe SSDs on a PCIe 3.0 backplane?

Yes, the cable is compatible with PCIe 3.0 and 4.0 motherboards and backplanes and does not require bifurcation.

How can I verify both U.2 drives are operating at PCIe 4.0 x8 after connecting the SlimSAS cable?

Check the OS device manager or BIOS to confirm each SSD negotiates a PCIe 4.0 x4 link, giving 64Gbps total bandwidth across the two drives.

Does the 15-pin SATA power connector on the cable power the U.2 SSDs, or do I need a separate power source?

The included 15-pin SATA power connector supplies power to both U.2 NVMe SSDs so no external PCIe power is required.
