Exactly. This is why high wattage USB-C cables rely on the power supply negotiating a higher voltage in order to work. Sending 100W over 5V would be ridiculous (20A). Instead the device tells the power supply to switch to 20V and then the cable only needs to be rated for 5A. Something like that for GPUs would make sense.
