UGREEN LinkStation CM980 eGPU Dock OCuLink 64Gbps USB4 Thunderbolt 4 850W ATX 3.1 Gold PSU

Dual-Interface eGPU Dock

The UGREEN LinkStation CM980 adds desktop-class graphics to laptops, handheld consoles and mini PCs through a 64Gbps OCuLink port and a 40Gbps USB4 Thunderbolt 4 port. An integrated 850W ATX 3.1 Gold power supply feeds the installed card and delivers 100W power delivery back to the host. The aluminium semi-open chassis uses vertical airflow to keep thermals in check during heavy workloads.

Included Cables and Compatibility

A 0.8m USB4 cable and a 0.5m OCuLink cable ship in the box so the dock works immediately with ROG Ally, Steam Deck OLED, Intel-based macOS machines, Windows 10 and 11 PCs and Linux systems. The 12VHPWR connector is native to the power supply, removing the need for adapters when installing modern RTX or Radeon graphics cards. Tool-free access lets builders swap cards without a screwdriver.

64Gbps OCuLink Bandwidth Decides Fit

The OCuLink interface runs at PCIe 4.0 x4 speeds with only 3-13% performance loss compared to an internal slot, making it the critical spec for buyers who need near-native GPU throughput. Devices lacking an OCuLink port fall back to the 40Gbps USB4 Thunderbolt 4 path, which carries a higher bandwidth penalty. Buyers whose hardware has neither interface cannot use this dock.
