PCIe 3.0 x4 to OCuLink SFF-8612 adapter

This LORDWORLD host adapter adds a single SFF-8612 OCuLink port to a desktop PC through a PCI Express 3.0 x4 slot. It is designed for users who want to connect an NVMe SSD externally using an optional cable. The bracket ensures a secure fit in standard chassis.

Sustained throughput at PCIe 3.0 speeds

The card transmits PCIe signals using the NVMe 1.2 protocol at up to 32 Gbps across four lanes. Because it operates at the PCIe 3.0 x4 limit, throughput remains consistent during extended transfers rather than throttling after a short burst. Performance scales with the attached drive and host platform capabilities.

Interface limits of PCIe 3.0 x4 and OCuLink

The SFF-8612 connector carries four PCIe 3.0 lanes, capping bandwidth at 32 Gbps regardless of the drive's own rating. Boot support requires UEFI 2.3.1 or newer, and the host must provide a free x4, x8, x16 or x32 slot. Compatibility covers Linux kernel 4.3 plus and Windows 8.1 through 10 64-bit.

Questions about this item

How much power does the PCIe 3.0 x4 host adapter draw when running an NVMe SSD all day?

The card itself is passive and draws negligible power from the PCIe slot; total consumption depends on the NVMe SSD you attach, which typically ranges from 5 to 10 watts under sustained load.

What cable do I need to connect an NVMe SSD to the SFF-8612 port on this adapter?

You need an OCuLink SFF-8612 to SFF-8611 or U.2 cable, sold separately, to carry the PCIe 3.0 x4 signal from the adapter to the NVMe drive.

Will this adapter boot an NVMe drive on a motherboard with UEFI 2.3?

The adapter requires UEFI 2.3.1 or newer for boot support; a motherboard limited to UEFI 2.3 will not recognise the NVMe drive as a boot device.
