Yesterday I attached a small USB fibre-optic ornament to the pc (White Bengal in system specs). I turned the pc off but didn't switch everything off from the wall-socket. The ornament remained lit. At first I thought it was extra charge in the PSU but not after an hour and more? This morning, I noticed the ornament lit up as soon as I switch on power from the wall socket. Even though pc is not powered and not running. I checked the same thing out on my previous pc (Black Panther in system specs) and the USB doesn't have current in it when the pc is off. Is there something wrong?
