PCIe 4.0 X8 to Dual OCuLink SFF-8612 Expansion Card, PCIe Bifurcation x4x4 Adapter, Up to 64Gbps, Support eGPU External Graphics & NVMe/U.2 SSD, Compatible with PCIe X8/X16 Slot, for Desktop PC

Product Description

1.Dual OCuLink SFF-8612 Ports via PCIe Bifurcation
Equipped with 2 x OCuLink (SFF-8612) external connectors, this adapter card splits one PCIe 4.0 x8 slot into two x4 channels (x4x4 bifurcation), letting you connect two external PCIe devices simultaneously — ideal for eGPU docks, external NVMe SSDs, U.2 drives and other high-speed peripherals.
2. PCIe 4.0 Full Speed, Up to 64Gbps Bandwidth
Supports PCI Express 4.0 at 16GT/s, delivering up to 64Gbps total bandwidth across the x8 interface — perfect for bandwidth-hungry external GPUs and fast NVMe storage. Fully backward compatible with PCIe 3.0 / 2.0 slots, so it works with older motherboards as well.
3.IMPORTANT — Motherboard Must Support PCIe Bifurcation
This card does NOT include a PCIe switch chip. It relies entirely on your motherboard's CPU/Chipset PCIe lane bifurcation feature (must be set to x4x4 or equivalent in BIOS). Please confirm your motherboard supports PCIe bifurcation before purchase — motherboards without this feature will only recognize one port or no device at all.
4. Fits Both PCIe X8 and X16 Slots, Low-Profile Ready
The card is designed for standard PCIe x8 and x16 motherboard slots (x16 slot runs at x8 bandwidth). Compact PCB with full-height bracket included; the angled connector layout keeps cabling clean and avoids blocking adjacent slots. Great for small form factor (SFF) PCs, ITX builds and workstations.
