LORDWORLD PCIe 4.0 16x to Dual Oculink SFF-8612 8X Adapter

PCIe 4.0 16x to Dual Oculink Adapter

This adapter converts a single PCIe 4.0 16x slot into two Oculink SFF-8612 8X ports, enabling connection of up to four PCIe storage devices. It is designed for users who need to expand internal high-speed storage using motherboard lanes that support bifurcation. The card includes onboard DC power modules to maintain stable operation across all connected drives. It suits builders adding multiple SSDs without occupying additional expansion slots.

Check motherboard PCIe bifurcation support

Before ordering, verify that your motherboard can split a 16x PCIe 4.0 lane into multiple 8x or 4x links, as the adapter only works with boards that expose detachable PCIe channels. Without bifurcation, the system will typically recognise only one drive per port. Ensure the 16x slot is electrically wired for 16 lanes and not shared with other onboard controllers. Confirm physical clearance for the dual Oculink connectors and any attached cables inside your chassis.

Integrates into bifurcation-ready builds

The card plugs directly into a 16x slot and provides two SFF-8612 ports, each carrying an 8X link for up to four drives total. It draws auxiliary power through onboard DC modules, so no external power cable is required. The design frees up additional PCIe slots that would otherwise be used for separate HBA or RAID controllers. Builders gain dense storage connectivity while leaving room for graphics cards or other expansion cards in remaining slots.
