PCIe 4.0 Slimline SAS Adapter

This new LORDWORLD adapter connects a Slimline SAS SFF-8654 port to an HD SFF-8643 connector. It supports SAS-to-SAS or PCIe-to-PCIe signals and works on both host and device sides thanks to a reversible design. Data rates reach 12 Gb/s over Mini SAS or PCIe 4.0 links. The card includes full-height and low-profile mounting brackets.

Compatibility Checklist

Verify that your host controller or backplane presents a Slimline SFF-8654 interface and that the target device uses an HD SFF-8643 port. Ensure the chassis has a free PCI slot opening that matches either the full-height or low-profile bracket supplied. Confirm the system firmware can train the link at PCIe 4.0 speeds if you require the maximum 12 Gb/s throughput.

Thermals and Power

The adapter is a passive PCB assembly with no onboard active cooling, so it adds negligible heat to the chassis airflow. Power draw is limited to the signal conditioning circuitry and remains well within the slot’s standard allocation. No fan noise is introduced, making the card silent in normal operation.

Questions about this item

Does the adapter include both full-profile and low-profile brackets?

Yes, the adapter ships with both full-profile and low-profile PCI slot mounting brackets.

Which version should I choose if my backplane uses SFF-8654 and my HBA uses SFF-8643?

This single model converts SFF-8654 to SFF-8643 and works in either direction, so no other version is needed.

Will the 12 Gb/s rating be reached on a PCIe 4.0 link?

The adapter supports up to 12 Gb/s Mini SAS or PCIe 4.0 data transfer, so the headline rate is achievable when the host and cables also meet that spec.
