How many USB C cable I need to power an ESP Thread Border Router/Zigbee Gateway board + Sub ethernet module ?

Hi.
I've just purchased an ESP Thread Border Router/Zigbee Gateway board + Sub ethernet module.
Anyway I've a doubt.
On the board there are two USB C ports that, I suppose, are needed to power the board + the sub thernet module.
The question is:
must I use two different USB cable connected to two, different, USB ports on the PC or is enough only one USB C cable to power all the system?
