UGREEN LinkStation eGPU Dock
Overview
The UGREEN LinkStation eGPU Dock is a full-size external GPU enclosure featuring a built-in 850W 80 Plus Gold ATX 3.1 power supply and dual connectivity via OCuLink (64Gbps PCIe 4.0 x4) and USB4 (40Gbps, compatible with Thunderbolt 4/3). Designed to accommodate full-size desktop graphics cards up to 370mm in length and 4 slots thick — including the RTX 5090, RTX 4090, and RTX 4080 — it delivers desktop-class GPU performance to laptops, handheld gaming PCs, and mini PCs. The semi-open aluminum chassis prioritizes thermal performance, and the USB4 port delivers up to 100W of power delivery to the host device for single-cable convenience. Unlike some competing eGPU docks, the LinkStation does not include an M.2 storage slot or Ethernet port, focusing purely on GPU expansion with an integrated high-wattage PSU.
