SMUGDESK 50cm PCIe 4.0 Slimline SAS Cable SFF-8654 8i 74Pin Male to Male
A 50 cm Slimline SAS 4.0 cable with dual SFF-8654 8i 74Pin locking connectors for PCIe 4.0 NVMe backplane links at 24 Gbps per lane
- PCIe 4.0 and SAS 4.0 deliver 24 Gbps per lane for enterprise NVMe storage
- 50 cm length reduces cable clutter, improving server airflow and heat dissipation
- Dual SFF-8654 8i 74-pin male connectors with locking tabs prevent disconnection from vibration
- Multi-layer shielding cuts crosstalk, ensuring stable 24/7 heavy-load operation
- Compatible with HBA, RAID controllers, backplanes and U.2 NVMe SSD enclosures
What this cable connects
This 50-centimetre Slimline SAS 4.0 cable uses SFF-8654 8i 74-pin male connectors on both ends to link a server HBA or RAID controller to a storage backplane or U.2 NVMe SSD enclosure. It follows PCIe 4.0 and SAS 4.0 specifications, delivering up to 24 Gbps per lane for enterprise NVMe storage. The design targets data-centre, enterprise array and high-performance workstation builds that need reliable internal high-speed links.
Installation and common issues
The connectors feature locking tabs that snap onto the port to resist vibration from fans or chassis movement, reducing the chance of accidental disconnection. Multi-layer shielding suppresses crosstalk and signal attenuation during continuous 24/7 heavy-load operation. No driver installation is required; the link is plug-and-play. The fixed 50 cm length cannot be adjusted, so cable routing must be planned before the chassis is closed.
Compatibility checks before ordering
Verify that both the host controller and the target backplane or enclosure present SFF-8654 8i 74-pin receptacles; other Slimline or Mini SAS form factors will not mate. Confirm the 50 cm reach suits your chassis layout without stretching or excessive slack that could impede airflow. Ensure the connected devices support PCIe 4.0 or SAS 4.0 signalling to use the full 24 Gbps per lane capability. This cable does not convert between different connector types or protocol versions.

Questions about this item
How do I verify the 24Gbps per lane link is active after connecting the SFF-8654 8i cable?
Check the HBA or RAID controller management utility for negotiated link speed and lane count; a healthy link shows 24Gbps on all eight lanes with zero CRC errors.
What comes with the 50cm Slimline SAS 4.0 cable and what must I source separately?
The package contains only the double-ended SFF-8654 74Pin male-to-male cable; compatible HBA/RAID cards, backplanes and U.2 NVMe drives are sold separately.
Which version of the SFF-8654 8i cable matches a PCIe 4.0 backplane?
This model is built to PCIe 4.0 and SAS 4.0 specifications, so it is the correct choice for any 24Gbps per lane backplane or controller port.
