Using 3 Monitor DP/HDMI Setup + Charging new Macbook Pro 16'' over max. 2 Cables
Caldigit TS3+ can do 87Watt charge with a firmware upgrade, my mac even at full load have not started discharging the battery with this.

Please be aware, that there are many users (including me), that has issues with external displays connected to the Macbook Pro 16" specifically.
It will pin the Radeon GPU at 18watt+ and keep the laptop fans spinning around 3k rpm and 60 degrees C at idle. 
Apple have not responded to the issue even calling support puts your trough random loops of tests that does nothing.
