LORDWORLD Oculink SFF-8611/8612 4i to PCI-E 16X Adapter with ATX 24Pin Power

SKU CH-7QA8-5DDT0

Connects a PCI-E 16x card via SFF-8611/8612 Oculink with ATX 24-pin 12V power support

  • Connect a 16x graphics card via Oculink 8611/8612
  • Power demanding cards with ATX 24-pin 12V supply
  • Supports standard PCI-E 16x, 8x and 4x expansion cards
  • Compatible with USB, LAN, 1394 and audio add-in cards
  • Installs internally through SFF-8611/8612 Oculink interface

Adapter purpose and audience

This LORDWORLD adapter connects a standard PCI-E 16x, 8x or 4x card to a host system through an Oculink SFF-8611 or SFF-8612 4i interface. It suits builders who want to run graphics cards, USB, LAN, 1394 or audio add-in cards in enclosures or backplanes that expose only an Oculink link.

Installation notes

The board installs internally and presents a full-size PCI-E slot plus an ATX 24-pin power connector with an onboard switch for 12 V auxiliary power. Builders must supply external ATX power when the attached card draws more than the Oculink link can deliver; forgetting this step is the most common cause of unstable operation.

Capacity and limits

The adapter passes a single PCI-E 16x, 8x or 4x device at the link width negotiated by the host Oculink port. It cannot drive multiple cards simultaneously, and it provides no benefit for workloads that require more bandwidth than the 4-lane Oculink connection can carry.

Highlights

  • Connect a 16x graphics card via Oculink 8611/8612
  • Power demanding cards with ATX 24-pin 12V supply
  • Supports standard PCI-E 16x, 8x and 4x expansion cards
  • Compatible with USB, LAN, 1394 and audio add-in cards
  • Installs internally through SFF-8611/8612 Oculink interface

Questions about this item

How can I confirm the Oculink SFF-8611/8612 adapter is functioning after connecting a graphics card?

The system should detect the PCI-E 16x, 8x or 4x device in Device Manager and the graphics card should output video without errors.

What comes in the box and do I need a separate Oculink cable?

The adapter board with ATX 24Pin power connector is included; an Oculink SFF-8611/8612 cable to link the host must be purchased separately.

Which version should I choose for a PCI-E 16x graphics card versus a 4x LAN card?

The same converter supports all standard PCI-E 16x, 8x and 4x cards, so one version covers both graphics and LAN devices.
