ADT-Link UT3G (USB4 / Thunderbolt 3-4 / ASM2464PDX / PCIe 4.0 x4 64Gb/s / Bare DIY Adapter / $128) Review
The ADT-Link UT3G is a bare USB4/Thunderbolt eGPU adapter board built on the ASMedia ASM2464PDX controller, providing PCIe 4.0 x4 (64Gb/s) bandwidth for DIY builds using your own case and power supply, priced at $128.
Our Razer Core X V2 and Sonnet enclosures are full pre-built boxes with their own power supplies, the UT3G is a completely different category, a bare adapter board for anyone building their own eGPU setup with an existing PSU, at a fraction of the price of a complete enclosure.
A Bare Adapter, Not a Complete Box
This is PCIe 4.0 x4 bandwidth over USB4/Thunderbolt in adapter-board form, no enclosure, no built-in power supply, you're supplying your own case and PSU. That's a real DIY project, not a plug-and-play solution, and the $128 price reflects that, it's a fraction of what a complete enclosure like the Core X V2 costs.
Real GPU Power Requirements Listed Upfront
ADT-Link is refreshingly specific about power needs by GPU tier, 300W+ PSU for entry cards, 450W+ for mid-range, 600W+ for high-end cards like the RTX 3080/4080 class, worth checking against whatever card you're actually planning to use before buying.
Comparison to Alternatives
Against our own Razer Core X V2, the Core X V2 is a complete enclosure with its own 850W PSU and toolless mounting, ready to use out of the box, the UT3G is the budget DIY route for anyone comfortable sourcing their own case and power supply. Against GPD's G1, also new here, the G1 is a complete portable dock at a premium price, the UT3G is the bare-bones alternative for builders who want to control every component themselves.
