Mini PC users may have OcuLink available for better performance.

Power Supply Considerations

Some enclosures include power supplies (AOOSTAR AG01/AG02, Sonnet 750ex) while others require you to supply your own. Built-in PSUs cost more but offer convenience and guaranteed compatibility. If choosing an enclosure without a PSU, ensure you have an ATX or SFX supply with sufficient wattage for your GPU - plan for at least 100W more than your GPU's rated maximum.

Bandwidth and Performance Expectations

Expect 15-20% performance loss with Thunderbolt 3/4 and USB4 compared to desktop mounting. OcuLink reduces this to 1-5% depending on the specific implementation. The bottleneck varies by game - GPU-bound titles see less impact than CPU-bound scenarios. Don't expect desktop-equivalent performance from Thunderbolt eGPUs.

Build Quality and Cooling

Open-frame designs offer better cooling but expose components to dust. Enclosed units are quieter but may throttle under sustained loads. Metal construction provides better heat dissipation than plastic. Check that the enclosure can accommodate your GPU's length and width - triple-fan cards often don't fit in compact docks.

Port Selection and Additional Features

Consider whether you need additional USB ports, Ethernet, or DisplayPort outputs. Some enclosures function as complete docking stations (Sonnet 750ex) while others are minimal. 85W PD charging is a valuable feature that can power your laptop while gaming.
