UGREEN LinkStation eGPU Dock costs $325
UGREEN has introduced a new LinkStation graphics card expansion dock with dual OCuLink and USB4 connectivity and a built in power supply. The dock is listed on Chinese retail platform for about 325 USD at current exchange rates. It ships with an 850W ATX 3.1 Gold rated PSU and targets users who want to pair desktop GPUs with thin and light laptops, handheld consoles, or compact Mini PCs.
The enclosure uses a semi open all aluminum design and supports graphics cards up to 370mm by default. A removable top cover gives extra clearance for longer boards. UGREEN advertises support for AMD, NVIDIA and Intel graphics cards, including current NVIDIA 40 and 50 series models thanks to the ATX 3.1 power supply and its native high power connectors.

On the host side, the LinkStation offers two connection options. The OCuLink port runs at 64 Gbps and exposes a PCIe link directly to the GPU, while the USB4 port operates at up to 40 Gbps for devices that only support Thunderbolt or USB4 eGPU setups. This combination allows the dock to move between laptops, handheld gaming PCs and small desktops without changing the graphics card or power supply.

Synthetic tests of OCuLink and USB4 eGPU setups using RTX 5090, RTX 4070 Ti and RTX 2060 SUPER cards show how these interfaces compare with a desktop PCIe slot. In 3DMark Port Royal, OCuLink kept around 94% of PCIe performance on average, while USB4 landed at around 83%. For pure GPU workloads this translates to roughly a 5 to 10% drop for OCuLink and about 15 to 25% for USB4, giving some context for what buyers can expect from UGREEN’s dual interface dock.
