  • Fits any free PCIe x4, x8, x16 or x32 slot with included bracket

OCuLink SFF-8612 host adapter for PCIe SSDs

This PCI Express card adds one external OCuLink SFF-8612 port to a desktop system. It connects a single NVMe SSD using an optional cable and includes a mounting bracket. The adapter fits a free PCIe x4, x8, x16 or x32 slot and operates with Windows 8.1 or 10 and Linux kernel 4.3 or above.

Bandwidth limits of the PCIe 3.0 x4 interface

The card transmits NVMe protocol signals over a PCIe 3.0 x4 electrical link, capping throughput at 32 Gbps. Although the connector is rated for PCIe 4.0 speeds up to 64 Gbps, the host slot determines the actual ceiling. Builders needing the higher 64 Gbps rate require a platform with native PCIe 4.0 x4 wiring.

Straightforward installation

The board seats in any compatible PCIe slot and secures with the supplied bracket; no extra power cable is needed. The most frequent issue is neglecting to verify UEFI 2.3.1 or newer for boot support, which prevents the attached drive from appearing as a startup device. Ensure the operating system meets the minimum version requirements before fitting the card.

Questions about this item

Should I use the x4 slot or a wider x8/x16 slot for this adapter?

The card plugs into any free PCI Express x4, x8, x16 or x32 slot and runs at x4 electrical width.

What does the 64 Gbps headline figure mean once the card is installed?

64 Gbps is the theoretical PCIe 4.0 x4 ceiling; actual throughput depends on the host slot generation and the connected NVMe SSD.

How does the SFF-8612 OCuLink interface limit performance in practice?

The external SFF-8612 connector carries four PCIe lanes, so bandwidth tops out at the host slot's PCIe 3.0 or 4.0 x4 limit.
