Oculink SFF-8611/8612 8i Adapter

This adapter connects a PCI Express x16 or x4 card to a system through an internal Oculink SFF-8611 or SFF-8612 8x interface. It supports graphics cards and add-in controllers such as USB, LAN, 1394 or audio. The board includes an ATX 24-pin power connector with a switch to supply 12 V auxiliary power when the installed card requires more current than the link provides. Oculink cable and host adapter are not included.

Build Integration

The converter installs inside the chassis and presents a standard PCI-E x16 slot for the expansion card. An ATX 24-pin power cable from the system power supply must be attached to the onboard connector and the switch set to enable 12 V delivery. No Oculink cable or host adapter ships with the unit, so the builder must source a compatible SFF-8611/8612 8x cable separately to link the adapter to the host.

Capacity and Headroom

The slot accommodates any standard PCI-E x16, x8 or x4 card, allowing full electrical connectivity for graphics or I/O controllers. Bandwidth is limited to the eight lanes carried by the Oculink 8x link, so x16 cards operate at x8 speed. The onboard 12 V ATX feed supplements slot power for higher-draw cards, but total delivery remains constrained by the host cable and power supply capabilities. Builders needing more than eight lanes or multiple cards should consider a different topology.

Questions about this item

How many PCIe lanes does the SFF-8611/8612 8i link provide for a graphics card?

The Oculink 8i interface delivers eight lanes, so a PCIe 16x card will operate at x8 electrical width.

Does the on-board ATX 24-pin connector add fan noise or heat during all-day operation?

The adapter has no active cooling; the ATX 24-pin port only supplies 12 V auxiliary power to the installed card.

Which separate items must I already own to make this adapter functional?

You need an Oculink host adapter or cable with SFF-8611/8612 8i connectors and an ATX power supply for the 24-pin plug.
