PCIe 4.0 x4 Oculink Adapter

This add-on card adds a single Oculink SFF-8612 x4 port to any system with a free PCIe slot. It targets builders who want to attach NVMe storage or an eGPU dock without opening the chassis for internal drives.

16 GT/s per lane headroom

Running at the PCIe 4.0 standard the adapter delivers 16 GT/s on each of four lanes for a 64 Gbps aggregate link. That bandwidth handles high-throughput NVMe workloads and external GPU traffic, while the x4 electrical width caps maximum throughput at that ceiling.

Welded connector and boot support

The SFF-8612 housing is welded to the PCB for a more secure plug-unplug cycle. The card also enables bootable NVMe devices and works plug-and-play under Windows, Windows Server and Linux with no extra drivers required.

Questions about this item

Will the PCIe 4.0 x4 adapter work in my older motherboard that only has PCIe 3.0 slots?

The card is built to the PCIe 4.0 standard and will run at PCIe 3.0 speeds when installed in a 3.0 slot, giving you 4 lanes of bandwidth for your Oculink device.

How can I verify the 16 GT/s per lane link is active after I install the card?

Check the link width and speed in your OS device manager or with a tool like lspci on Linux; it should show x4 at 16 GT/s when a compatible Oculink SFF-8612 cable and device are connected.

Does the package include the SFF-8611 cable needed to reach an eGPU dock, or do I buy that separately?

The box contains only the PCIe x4 to 1-port Oculink SFF-8612 adapter; the SFF-8611 cable for connecting NVMe SSDs or eGPUs must be purchased separately.
