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.

UGREEN LinkStation eGPU Dock

7.5 / 10 Expert Rating

A strong-value, high-wattage dual-connectivity dock from a large, well-established accessories brand — a serious new competitor in the OCuLink space.
