      Technical Notes

      • Apple notebooks with 45-60W AC power adapters may be powered and charged by the eGPU Breakaway Puck, even while gaming. Apple notebooks with AC power adapters rated at 85-100W will accept 60W power from the Puck but will slowly discharge. Connecting bus-powered storage to a laptop will draw additional power that may affect the charging (discharging) rate. When sleeping, any connected computer that supports Thunderbolt 3 charging will be charged to 100% by the Puck.
      • Support for four 4K monitors requires a Sonnet Thunderbolt 3 to Dual HDMI 2.0 Adapter or Thunderbolt 3 to Dual DisplayPort Adapter (both sold separately).
      • Ultimate gaming performance is attained by using a display attached to eGPU.
