ARCTIC

ARCTIC PCIe 4.0 to Oculink SFF-8612 Adapter 2 in 1 Accessory

SKU CH-XCX4-FAHWR

Adds a PCIe 4.0 Oculink SFF-8612 x4 port for NVMe SSDs or eGPUs via SFF-8611 cable, delivering 16 GT/s per lane across eight lanes for 128 Gbps total bandwidth

  • Add an Oculink SFF-8612 x4 port via PCIe slot for NVMe SSDs or eGPUs
  • PCIe 4.0 at 16 GT/s per lane across 8 lanes delivers 128 Gbps total bandwidth
  • Welded connector housing on PCB gives a secure, durable plug-and-unplug connection
  • Works as a bootable device for flexible system startup options
  • No driver installation needed — plug and play across multiple operating systems

PCIe 4.0 Oculink Adapter

This ARCTIC adapter adds an Oculink SFF-8612 x4 interface through a PCIe slot, letting you connect NVMe SSDs or eGPUs using an SFF-8611 cable. It supports the PCIe 4.0 standard at 16 GT/s per lane across 8 lanes for 128 Gbps total bandwidth. The welded connector housing secures the connection to the PCB for durability. No driver installation is required for plug-and-play operation.

Bootable Device Support

The card enables bootable device functionality, giving you more options for system startup and increasing overall flexibility. You can use the attached NVMe SSD as a primary boot drive if your platform allows it. The plug-and-play design works across a variety of operating systems without extra software. Welded connectors reduce fragility during repeated cable changes.

Desktop Builders Adding Oculink

Suits desktop builders who need an Oculink SFF-8612 port for NVMe SSDs or eGPU docks and have a free PCIe slot. Not for laptops or small-form-factor systems lacking a full-size PCIe slot. Buyers without an SFF-8611 cable or compatible NVMe/eGPU device cannot use the adapter. Platforms that do not support booting from PCIe add-in cards will not benefit from the bootable feature.

Highlights

Questions about this item

Will the SFF-8612 connector or the PCIe 4.0 slot need replacement after repeated plug cycles?

The connector housing is welded to the PCB for a more secure connection and reduced fragility during plug-and-unplug use.

Does the x8 link or the 16 GT/s per lane limit appear first during sustained transfers?

The adapter runs at PCIe 4.0 with 16 GT/s per lane across 8 lanes, so the lane speed and lane count define the 128 Gbps ceiling together.

Does the card add noticeable heat or fan noise when an NVMe drive runs all day?

No active cooling is present on the adapter; thermal load depends on the attached drive and the host chassis airflow.
