Oculink SFF-8611 SFF-8612 to PCIe X16 X4 Adapter Card with SATA Power Port, Convert OCuLink Interface for Motherboard External Graphics Card eGPU Expansion

This Oculink conversion adapter is specially designed for mini motherboards, NUC and ITX small form factor hosts to realize external graphics card expansion. It seamlessly converts SFF-8611/SFF-8612 OCuLink high-speed interface into universal PCIe X16 (runs on PCIe X4 lane) slot, allowing you to mount full-size desktop graphics cards externally and boost system gaming, 3D modeling and video rendering performance.

Equipped with independent SATA power input, it supplements stable power output for the adapter and connected GPU, effectively solving the problem of limited power supply from the motherboards OCuLink port under high load. The PCB adopts reinforced circuit design and locking-type OCuLink terminals to prevent loose contact during equipment vibration, ensuring continuous and low-latency PCIe signal transmission.

Besides external GPU setup, it also supports other PCIe X4/X8/X16 expansion devices such as high-speed SSD adapters, network cards and capture cards. Plug and play with full driver support for mainstream operating systems, an ideal hardware upgrade accessory for compact mini PCs, portable workstations and DIY eGPU projects.

Note: OCuLink interface does not support hot plug, please power off the host completely before plugging or unplugging the device.
