  • Designed and made in Taiwan with green LED status indicator

PCIe 4.0 x16 to dual SFF-8654 adapter

This PCIe 4.0 x16 add-in card converts the slot into two SFF-8654 8i ports using a built-in ReDriver. It supports 16 GT/s signalling across 16 lanes that can be bifurcated into four x4 links. The card includes clock, PERST, WAKE, CLKREQ and PWRBRK buffers for extended trace and cable runs. A green D1 LED shows when the adapter is ready.

Verify slot bifurcation and cable pin-out

Confirm that your motherboard or riser can bifurcate a x16 slot into four x4 links before ordering. The SFF-8654 connectors follow the SFF-9402 Rev 1.1 pin-out, so cables must match that specification. The on-board 100 MHz clock buffer and SMBus switch with reset function require a UEFI 2.3.1 or later firmware for full initialisation. Windows 7, 8, 8.1 and 10 are supported operating systems.

Sustained operation with signal buffering

Integrated ReDriver and bus buffers maintain 16 GT/s signal integrity over longer cables during continuous rack-server workloads. The clock buffer drives extended trace lengths without degrading the 16-lane link under constant throughput. PERST, WAKE, CLKREQ and PWRBRK buffering prevents link drops when the system remains under load for extended periods. The adapter is designed and made in Taiwan for reliable long-term deployment.

Questions about this item

Does the board ship with any SlimSAS cables, or do I need to source SFF-8654 8i cables separately?

The adapter is supplied as a bare card; SFF-8654 8i cables are not included and must be purchased separately.

The card offers a single x16 slot and dual 8i ports — how do I decide which lane split to use?

The on-board ReDriver supports bifurcation of the 16 lanes into four x4 links, so you can run two x4 connections to the dual 8i ports or configure other topologies as your server requires.

What does the 16 GT/s Gen 4 rating mean for real-world throughput when the card is installed in a rack server?

Each lane runs at 16 GT/s per the PCIe 4.0 specification, giving a raw 16-lane link; sustained transfer rates will depend on the attached SSDs, cable quality and server backplane design.
