OCuLink eGPU Dock with PCIe 4.0 x4 64Gbps

This OCuLink eGPU dock is designed to expand the graphics processing and PCIe connectivity of desktop terminals, mobile computing devices and high-performance single-board computers such as the LattePanda series. Using a native PCIe 4.0 x4 physical lane interface, this external GPU dock provides up to 64Gbps data transfer bandwidth for discrete graphics cards and other high-speed PCIe devices.

PCIe 4.0 x4 with Up to 64Gbps Bandwidth

This OCuLink graphics card dock uses a native PCIe 4.0 x4 connection and provides up to 64Gbps bandwidth. The high-speed interface is designed to reduce data transfer bottlenecks when connecting external graphics cards, high-speed network adapters, RAID cards, capture cards and other PCIe expansion devices.

ReDriver Signal Enhancement for Stable High-Speed Transmission

This PCIe expansion dock integrates a ReDriver signal enhancement chip to compensate for high-frequency signal attenuation and reduce signal loss over the external connection path. This design helps maintain more stable PCIe communication when high-speed devices are connected through the OCuLink data cable.

Flexible Power Supply Support for Different GPU Classes

This eGPU dock uses a standard ATX-24P connector for motherboard power and supports dedicated 16-pin or 8-pin/6-pin power connections for graphics cards. The open bracket architecture supports standard ATX, SFX and FLEX (1U) power supplies. For system stability under load, a 300W or higher power supply is recommended for entry-level graphics cards, 450W or higher for mid-range graphics cards, and 600W or higher for high-end flagship graphics cards.

Synchronized Host Power Control

This external GPU docking station supports automatic synchronization with the host power state, allowing the dock, graphics card and external power supply to coordinate startup and shutdown with the connected host. LED indicators provide direct status feedback, with solid blue indicating standby mode and solid green indicating startup.

Compatible with GPUs and Standard PCIe Expansion Cards

This OCuLink expansion dock supports NVIDIA, AMD and Intel discrete graphics cards and is also backward compatible with standard PCIe expansion devices such as high-speed network cards, discrete sound cards, RAID cards and video capture cards. Supported operating systems include Windows 10/11 and Ubuntu.
