PCIe Gen4 internal cable for NVMe backplanes

This 50 cm internal cable uses two SlimSAS SFF-8654 4i male-to-male connectors to link a backplane to a motherboard or RAID/HBA controller. It supports PCIe Gen4 speeds up to 32 GT/s per lane across four lanes for high-bandwidth NVMe SSDs. The shielded construction uses silver-plated copper, fluoropolymer and glass-filled thermoplastic for reliable operation.

Servers and workstations needing direct NVMe links

The cable suits builders integrating NVMe backplanes into rackmount servers, workstations or industrial PCs where a 50 cm reach fits the chassis layout. It is not for setups that require longer runs between the controller and the backplane. Buyers needing a different connector style or a higher current rating than 0.5 A should look at other options.

PCIe Gen4 x4 lane speed rating

The decisive specification is the PCIe Gen4 x4 lane capability delivering up to 32 GT/s per lane. This bandwidth determines whether the cable can saturate modern NVMe drives without becoming the bottleneck. Verify that the host controller and backplane both support this generation and lane width before purchasing.

Questions about this item

What clearance does the 50 cm SlimSAS SFF-8654 4i cable need inside a chassis?

The 50 cm length and shielded silver-plated copper construction require enough straight run between the backplane and controller to avoid sharp bends that could damage the fluoropolymer insulation.

Which way round do the two male SFF-8654 4i connectors go during installation?

Both ends are identical male-to-male plugs; either end can attach to the backplane or the RAID/HBA card, so there is no keying mistake to avoid.

When should the cable be replaced in a server running at the 70 °C limit?

Continuous operation at the 70 °C / 158 °F maximum rating accelerates insulation ageing; plan replacement if the jacket shows discoloration, cracking or the 0.5 A rating can no longer be sustained.
