Oculink SFF-8612 SFF-8611 Adapter

This adapter converts an Oculink SFF-8611 or SFF-8612 interface into a PCIe x16 slot that operates at up to x4 electrical width. It accepts standard PCIe x16, x8 or x4 cards such as graphics, USB, LAN, 1394 or audio controllers. A SATA power port supplies up to 12 V 2 A for auxiliary power.

Upgrade from proprietary or limited slots

The converter lets you install a full-size PCIe expansion card in systems that only expose an Oculink 4x connection. It is worth the change when the host platform provides an Oculink port but lacks a native x16 slot for the desired add-in card.

Check host port and card power draw

Verify that the mainboard or backplane presents an SFF-8611 or SFF-8612 Oculink 4x connector. Confirm the target PCIe card does not require more than 12 V 2 A from the adapter's SATA power port; connect supplemental power directly to the card if its demand exceeds that limit.

Questions about this item

What clearance does the 10 cm by 10 cm board need inside the case?

The adapter measures 10 cm by 10 cm by 1 cm, so allow at least that footprint plus room for the SFF-8611 or SFF-8612 cable bend radius and the SATA power connector.

Which SFF-8611 or SFF-8612 port do I plug the OCuLink cable into, and which way does the latch face?

Insert the OCuLink cable into the onboard SFF-8611 or SFF-8612 receptacle with the latch facing the PCB edge; the connector is keyed so it only seats one way.

When should I replace the SATA power lead if I run a 12 V 2 A graphics card continuously?

Inspect the SATA power cable every 12 months; replace it if the pins show discoloration or the insulation becomes brittle from sustained 12 V 2 A load.
