PCIe 4.0 Slimline SAS SFF-8654 Female to Mini SAS HD SFF-8643 Female PCBA Adapter Card with Full Height & Low Profile Bracket

This professional PCIe 4.0 signal conversion PCBA adapter features Slimline SAS SFF-8654 female input and Mini SAS HD SFF-8643 female output, supporting bidirectional signal transmission for enterprise server storage interconnection.

Strictly designed following PCI Express 4.0 and SAS 4.0 industrial standards, it maintains full-bandwidth lossless data transfer for NVMe SSD arrays, SAS hard drives and RAID card backplane connection. The PCB adopts multi-layer shielding layout and gold-plated conductive terminals, effectively suppressing electromagnetic interference and avoiding overheating under 24/7 full-load operation in data center environments.

It is equipped with a sturdy metal full-height mounting bracket, and a matching low-profile bracket is included for slim 1U/2U rack servers, which can be firmly fixed to standard PCI slot positions to prevent loose contact caused by fan vibration.

The reversible signal architecture allows flexible matching of new-generation SFF-8654 RAID controllers and traditional SFF-8643 storage backplanes, eliminating the need to replace server hardware during storage upgrade. No driver or complex BIOS configuration required, plug-and-play compatible with mainstream Windows, Linux and VMware ESXi server systems.

Ideal hardware accessory for rack server storage expansion, NAS disk array construction, high-speed computing workstations and hardware signal testing projects.
