Hello, I own a MSi B450 Gaming Plus Max Motherboard, and I notice that only one of my USB ports are powered after I shut down my computer(USB Mouse plugged in and the lights are on even the pc is off). So I removed my USB mouse and plugged it in the other port, now the said powered port was unused now. I'm wondering to plug in any LED devices to that(Thinking maybe an LED clock that needs to stay on) so that it stays on even my computer is off, Is it safe to plug in any powered devices such as LED lamp,clock,lights, etc. to the said port? and just keep it powered?
