Some USB ports, on new systems will remain on (charging port) even if the PC is powered off. There may be a BIOS option to have this or not. I have the option on my new ASUS motherboard. My new Dell Laptop has one USB port that has power when off.
It's just typical, that ever since the PSU turns on via a wire from the motherboard, there has to be power on the motherboard, for the power ON switch.
My own Gigabyte motherboard has a green LED on it that will stay on even after I Power Down the PC. There is also a very bright Blue LED on the Multi-Card-Reder that will stay on. Those tend to remind me to switch off the power to the PC, at the Power Strip on the back of my PC Desk. Modern PC's are never really OFF till you remove the power from them. They are much safer that way. That is NOT programmable! It's just the way they are made.
