[Thunder3 Dock Pro] Is 60W enough for the 15" MacBook Pro?

The 15" MBP comes with a 87W power supply, because it has four Thunderbolt 3 ports and needs to provide a lot of power in case all of the ports are occupied by bus-powered peripherals. For example, with the PSU connected to one of the ports (87W), two bus-powered Thunderbolt 3 devices (2 x 15W) and one bus-powered USB device (7.5W), that will leave about 50W for the computer (87W - 15W - 15W - 7.5W = ~50W).

In the scenario above with three bus-powered devices connected to the computer, 60W is insufficient. However, if you connect one bus-powered Thunderbolt 3 device to the second Thunderbolt 3 port on the docking station, use the built-in USB ports for the USB drive and do not connect any bus-powered devices directly to the computer, 60W as provided by the Thunder3 Dock Pro is enough to power the computer..
