### ⭐⭐⭐ Defective motherboard
*by S***S on 15 October 2021*

Unfortunately, the motherboard I received was defective, with the error "USB over current detected" being report by BIOS, with no USB device connected to the motherboard. I suspect this may have been used before I received it. Not a happy customer.
