The Ultimate Guide to the UGREEN LinkStation Pro
The UGREEN LinkStation Pro is an external GPU dock designed to bring desktop-class graphics performance to compatible laptops, mini PCs, handhelds, and other systems.
It is the upgraded version of UGREEN's earlier LinkStation eGPU dock. The biggest change is the move from 40Gbps USB4 to Thunderbolt 5 with up to 80Gbps bandwidth, while the dock keeps its direct OCuLink connection for systems that support it.
The other major feature is its built-in 850W ATX 3.1 power supply, meaning users do not need to purchase a separate desktop PSU for the graphics card.
⚡ 850W ATX 3.1 Power Supply
The LinkStation Pro includes an integrated 850W 80 PLUS Gold-rated ATX 3.1 power supply.
This gives the dock enough power headroom for modern high-performance desktop GPUs without requiring an external power brick or separate ATX PSU.
The power system includes:
850W integrated PSU
ATX 3.1 specification
80 PLUS Gold rating
Native 12V-2x6 GPU power connector
Two PCIe 6+2-pin cables
Four 8-pin connectors through the included cables
Support for GPUs requiring up to three 8-pin power inputs
The native 12V-2x6 connection is particularly useful for newer GeForce RTX graphics cards that use the newer power connector standard.
🚀 Thunderbolt 5 Bandwidth
The biggest upgrade over the previous LinkStation is Thunderbolt 5.
The LinkStation Pro supports up to 80Gbps of Thunderbolt 5 bandwidth. The connection can provide up to 64Gbps of PCIe 4.0 x4 bandwidth to the graphics card.
Thunderbolt 5 vs OCuLink
| Connection | Advertised bandwidth | Main purpose |
|---|---|---|
| Thunderbolt 5 | Up to 80Gbps | Flexible eGPU and docking connection |
| OCuLink | Up to 64Gbps | Direct PCIe 4.0 x4 eGPU connection |
| USB4 | Up to 40Gbps | Supported through backward compatibility |
| Thunderbolt 4 | Up to 40Gbps | Backward compatibility |
| Thunderbolt 3 | Up to 40Gbps | Backward compatibility |
The advertised 80Gbps figure should not be treated as equivalent to 80Gbps of raw GPU data throughput. Protocol overhead and the way the host system implements the connection affect real-world performance.
🔌 OCuLink Support
UGREEN has kept OCuLink on the Pro model instead of making Thunderbolt 5 the only connection option.
The OCuLink connection provides a PCIe 4.0 x4 link rated at up to 64Gbps, giving compatible systems a more direct PCIe path to the external GPU.
This makes the LinkStation Pro particularly interesting for mini PCs and other systems that already include an OCuLink port.
The two connection methods serve different needs:
Thunderbolt 5: Easier cable-based connectivity and additional docking functionality.
OCuLink: More direct PCIe connectivity for compatible systems.
🎮 eGPU Compatibility
The LinkStation Pro uses a full-size desktop GPU slot, allowing users to install a dedicated desktop graphics card inside the enclosure.
Reported compatibility includes GPUs from NVIDIA, AMD, and Intel, although actual compatibility depends on the host system, operating system, drivers, physical dimensions, and power requirements.
The enclosure is designed for large graphics cards, with reported support for cards up to around 370mm in length and 155mm in height.
That means the dock is not limited to small-form-factor GPUs.
Before installing a card, users should still check:
GPU length
GPU height
GPU thickness
Power connector requirements
Host Thunderbolt or OCuLink support
Operating system support
GPU driver compatibility
💻 140W Laptop Charging
The LinkStation Pro also works as a more capable docking station.
Through USB Power Delivery 3.1, it can provide up to 140W of power to compatible laptops. This is an increase over the previous LinkStation's reported 100W charging capability.
This makes it possible for a compatible laptop to receive power while also connecting to the external GPU through a single Thunderbolt connection.
Actual charging power depends on the connected computer and its supported USB PD profile.
🔗 Ports and Expansion
The Pro model includes more connectivity than the original LinkStation.
Reported connectivity includes:
3x Thunderbolt 5 ports
1x USB-A 3.2 port
OCuLink
Full-size PCIe GPU slot
Integrated 850W power supply
The Thunderbolt 5 ports also support daisy chaining, allowing additional compatible Thunderbolt devices to be connected without running every device directly to the host computer.
UGREEN also advertises support for multi-display configurations, including up to three displays and 8K output in reported specifications.
🖥️ Who Is the LinkStation Pro For?
The LinkStation Pro is mainly aimed at users who want desktop GPU performance without building a traditional desktop tower.
It can be useful for:
Gaming laptops
Mini PCs
Compatible handheld PCs
AI development systems
Content creation
3D rendering
Video editing
Workstation applications
Compatible NAS systems
The most important requirement is having a host device that can properly support the required Thunderbolt 5 or OCuLink connection.

🎮 The Bottom Line
The UGREEN LinkStation Pro combines three major pieces of eGPU hardware into one enclosure: an 850W ATX 3.1 power supply, Thunderbolt 5 connectivity up to 80Gbps, and OCuLink up to 64Gbps.
Its biggest advantage is flexibility. Thunderbolt 5 makes the dock useful for compatible laptops and other systems that need a simple high-speed external connection, while OCuLink gives compatible devices a more direct PCIe route to the GPU.
With support for large desktop graphics cards and up to 140W laptop charging, the LinkStation Pro is designed to turn compatible portable or compact systems into considerably more capable GPU platforms.
