Slimline MCIO 8i to dual SFF8654 4i cable, 0.5m

SMUGDESK

SMUGDESK Gen5 Slimline MCIO 8i PCIe 5.0 SFF8654 8i to Dual SFF8654 4i Cable 0.5M

SKU CH-NZTG-FGSD9

Splits a single SFF-8654 8i port into two SFF-8654 4i connections for PCIe 5.0 NVMe storage at 32 Gbps over a .5 m low-loss copper harness

  • Splits one SFF8654 8i port into two SFF8654 4i ports for flexible NVMe expansion
  • PCIe 5.0 compliant design enables 32Gbps bandwidth for enterprise NVMe SSDs and RAID controllers
  • Low-loss copper conductors minimize signal attenuation and crosstalk for stable long-term performance
  • Heavy-duty shielding optimizes signal integrity in high-density data center and workstation deployments
  • Available in 0.5m and 1m lengths to fit compact and standard server chassis layouts

PCIe 5.0 breakout cable for NVMe expansion

This Gen5 Slimline MCIO cable splits a single SFF-8654 8i port into two SFF-8654 4i connectors. It supports PCIe 5.0 at 32Gbps for high-speed NVMe SSD and RAID controller links. The .5 metre length suits compact server chassis routing. Premium low-loss copper and heavy shielding maintain signal integrity in dense deployments.

Upgrades direct-attach or older-gen cabling

Replaces single-port cables or PCIe 4.0 assemblies when density and throughput must scale together. The one-to-two breakout adds a second NVMe device without consuming another HBA port. The jump is worth it when your backplane or RAID card needs two 4i links from one 8i source. Not for builders who need more than two 4i branches or a different connector family.

Verify port layout and cable reach first

Confirm your HBA, RAID card or motherboard exposes an SFF-8654 8i receptacle wired for PCIe 5.0. Ensure each target drive or backplane accepts an SFF-8654 4i plug. Measure the internal path to ensure .5 metre (19.68in) covers the run without tension. Not for external enclosures or mixed-connector topologies.

Questions about this item

What connector spacing does the SFF-8654 8i end require on the motherboard or backplane?

The cable splits one SFF-8654 8i port into two SFF-8654 4i connectors, so the source side needs a single 8i receptacle with standard pitch.

Which step do installers most often miss when routing the .5M harness?

They forget to seat both 4i ends fully until the latch clicks, leaving one NVMe link running at reduced width.

When should the copper harness be replaced in a 32Gbps NVMe array?

Replace it if link errors appear, after a chassis rebuild that stresses the cable, or when upgrading to a newer PCIe 5.0 controller that demands tighter signal margins.
