Green PCIe add-in card with four silver SFF-8612 Oculink ports, full-height bracket

Vszerda

Vszerda PCIe 4.0 to Oculink SFF-8612 Adapter SFF-8611

SKU CH-EXWT-9ZFBN

Adds an Oculink SFF-8612 x4 port via PCIe 4.0 for NVMe SSDs or eGPU docks at 256 Gbps

  • Adds Oculink SFF-8612 x4 port via PCIe slot for NVMe SSDs or eGPU docks
  • PCIe 4.0 delivers 16 GT/s per lane across 16 lanes for 256 Gbps total throughput
  • Connector housing welded to PCB for secure, durable plug-and-unplug cycles
  • Requires motherboard PCIe x4x4x4x4 bifurcation support to function
  • Uses SFF-8611 cable to link external GPU docks or NVMe storage enclosures

PCIe 4.0 Oculink SFF-8612 Adapter

This Vszerda adapter adds an Oculink SFF-8612 x4 interface through a PCIe slot, enabling connections to NVMe SSDs or eGPU docks via an SFF-8611 cable. It targets builders expanding storage or graphics capability on platforms that support the required signal splitting.

Sustained 16 GT/s per lane throughput

The card operates at the PCIe 4.0 standard, delivering 16 GT/s per lane across 16 lanes for a total of 256 Gbps bandwidth. This high-throughput design maintains swift data read and write performance during prolonged heavy workloads involving large data volumes.

Replaces limited native I/O when bifurcation exists

It upgrades systems lacking sufficient high-speed ports, provided the motherboard supports PCIe x4x4x4x4 bifurcation. Without that splitting capability the adapter cannot function, so the jump is only worth it on compatible platforms needing extra NVMe or eGPU links.

Questions about this item

How much power does the Vszerda PCIe 4.0 to Oculink adapter draw when running all day?

The adapter itself is passive and draws negligible power; the 256 Gbps link budget is consumed by the attached NVMe SSD or eGPU, so total system draw depends on those devices.

What motherboard feature must I already have for this card to function?

Your motherboard must support PCIe x4x4x4x4 signal bifurcation so the single x16 slot can split into four x4 lanes for the SFF-8612 connector.

Will this work in an older PCIe 3.0 slot I plan to keep?

Yes, the card is backward compatible and will operate at PCIe 3.0 speeds, reducing the per-lane rate from 16 GT/s to 8 GT/s.
