Peladn Link S-3 Debuts as First Thunderbolt 5 eGPU Dock with SSD Expansion, 2.5G LAN, and More
Subtitle:
With broader I/O and ATX/SFX PSU support, the Link S-3 aims to outperform OCuLink docks with Thunderbolt 5 versatility for $223.
Thunderbolt 5 Takes Center Stage
Peladn has unveiled its most advanced external GPU dock yet: the Link S-3, the company’s first eGPU enclosure to support Thunderbolt 5. Positioned as a next-gen alternative to OCuLink-based docks, the Link S-3 combines GPU expansion with a suite of practical connectivity options typically absent in its competitors.
- Supports both ATX and SFX power supplies, up to 180 mm in length
- Includes dual Thunderbolt 5 ports for high-bandwidth connectivity
- Now available to pre-order in China for CNY 1,599 (~$223)
- Shipping begins July 26; no global release confirmed yet
Thunderbolt 5 vs. OCuLink: Performance & Trade-offs
While OCuLink remains a go-to for pure GPU performance due to lower latency, Thunderbolt 5 brings greater flexibility:
- Thunderbolt 5 theoretical bandwidth: 80 Gbps
- However, PCIe 4.0 x4 passthrough caps GPU data at 64 Gbps, matching OCuLink
- Higher latency in Thunderbolt may affect real-world gaming performance slightly
- In return, Thunderbolt 5 enables multi-functionality from a single port

Added Features Make It a Full Dock, Not Just an eGPU
The Peladn Link S-3 is more than a GPU enclosure—it’s a compact I/O hub that rivals traditional docking stations:
- 2.5 Gigabit Ethernet via Realtek RTL8156B
- SD card reader
- USB 3.2 Gen 2 (10 Gbps) Type-A port
- M.2 2280 SSD slot (PCIe 3.0 x1) hidden discreetly at the bottom
- 140 W Power Delivery for charging connected devices
These features make it ideal for creatives, mobile workstation users, and developers who need GPU power and rich expansion from one device.
GPU Compatibility and Power Supply Flexibility
- Supports desktop-class graphics cards via PCIe slot
- Compatible with both SFX and full-size ATX power supplies
- Offers robust cooling and component layout options within a compact chassis
This flexibility gives users a level of customizability typically seen in larger DIY eGPU setups.
