Fervit 4 Port PCIe 4.0 x16 Oculink Adapter 12cm Bracket

SKU CH-28B6-RJ1T6

Converts a PCIe 4.0 x16 slot into four OCuLink ports for SSDs or eGPUs at up to 64 Gbps with a 12 cm bracket

  • PCIe 4.0 delivers up to 64 Gbps bandwidth
  • Four OCuLink ports add SFF-8611/8612 connectivity
  • 12 cm bracket fits compact chassis
  • Backward compatible with PCIe 3.0 and 2.0
  • Requires motherboard with bifurcation for four drives

Four-Port PCIe 4.0 Oculink Adapter

This Fervit adapter converts a single PCIe 4.0 x16 slot into four Oculink SFF-8611 and SFF-8612 ports. It targets builders who need to attach SSDs or an external GPU enclosure in compact systems. The 12 cm bracket provides mounting points for secure installation. Buyers without a motherboard supporting PCIe bifurcation should look elsewhere.

Bifurcation Requirement

The card only functions with motherboards that expose detachable PCIe channels. Without signal splitting, the board will recognise only one connected drive. PCIe 4.0 operation delivers up to 64 Gbps per port and remains backward compatible with PCIe 3.0 and 2.0. Verify your platform supports bifurcation before purchasing.

SAS-4 Compatibility

Each Oculink connector complies with the SAS-4 24 Gbps standard, allowing direct attachment of compatible storage devices. No cables are bundled, so you must source SFF-8611 or SFF-8612 cables separately. The adapter adds no software or drivers; it is a passive electrical bridge.

Questions about this item

What does the 64Gbps headline rate actually deliver when the adapter is installed in a PCIe 4.0 x16 slot?

The adapter presents four OCuLink ports that together share the full 64Gbps bandwidth of a PCIe 4.0 x16 link, so each connected SSD or eGPU can use up to that aggregate limit depending on how the motherboard divides the lanes.

Which connector standard does the card use and what speed does it cap at per port?

Each port follows the SFF-8611 and SFF-8612 OCuLink specification and is compatible with SAS-4 at 24Gbps, so a single port cannot exceed 24Gbps even though the slot provides 64Gbps total.

What physical space and mounting does the 12cm bracket require inside the case?

The card fits a standard PCIe x16 slot and ships with a 12cm tall bracket that includes fixing holes, allowing it to be secured in a full-height or low-profile chassis opening.
