A:AnswerThe 600 series of motherboards is incompatible with ryzen cpus below ryzen 7000. Your ryzen 5600x has a different socket and is not compatible with any 600 series motherboard ( A620, B650, X670 ). It is however compatible with all 500 series motherboards and some 400 and even 300 series motherboards, though I would suggest going with a B550 motherboard. Dont get the A520 motherboard as you have a X series chip which draws more power.
