Specs
| Specification |  |  |
|---|---|---|
| Connection Standard | Two Thunderbolt 5 ports, theoretical 80Gbps bidirectional, with DisplayPort 2.1 Alt Mode; internal PCIe 4.0 x4 slot for the graphics card | Thunderbolt 5, 80Gbps (backward compatible with Thunderbolt 4 / USB4); internal PCIe Gen 4 x4 slot |
| Brand | PELADN | Plugable |
| Extra Ports | 2x Thunderbolt 5, 1x USB 3.2 Gen 2 Type-A, 1x M.2 2280 SSD slot (PCIe 3.0 x1), 2.5GbE Ethernet (RTL8156B), SD card reader | 1x downstream Thunderbolt 5 (15W PD), 1x USB-C 10Gbps (15W), 3x USB-A 10Gbps (7.5W each), 2.5GbE Ethernet |
| Host Power Delivery | 140 | 96-31% |
| Max GPU Length | 3.5-99% | 346 |
| Cooling Type | Passive/slim chassis cooling for the dock itself; GPU cooling is entirely down to the card, similar to most bare-bones eGPU docks | Single internal enclosure fan; GPU must supply its own cooling solution |
| Model | Link S-3 | TBT5-AI |
| Price | Roughly $278 USD equivalent in Canada (~$384 CAD) at launch, but reported as high as $460 USD via AliExpress for the US market due to tariffs — pricing has varied significantly by region, so treat any single figure as a snapshot rather than a fixed MSRP | $629.99 launch price, enclosure only (GPU sold separately) |
Verdict
PELADN Link S-3
6 / 10 Expert Rating
An interesting, genuinely cheaper-to-build Thunderbolt 5 eGPU option for people who already have a spare ATX/SFX PSU, but inconsistent regional pricing and near-zero independent review coverage mean it's a bigger gamble than the budget framing suggests.
Plugable Thunderbolt 5 AI eGPU Enclosure & Dock
7 / 10 Expert Rating
A genuinely differentiated, well-specced Thunderbolt 5 eGPU box for local-AI GPU hosting, but it's brand new, Windows-only, and still awaiting independent benchmarking — treat the manufacturer's numbers as a starting point, not a verified ceiling.
