What can I say...sadly it happens. But I'd totally go B450 too...preferably B450M Mortar, B450M Bazooka Plus (if you can find one), B450M Gaming Plus. Very strong VRM's with 4 'big' phases and heavy duty well finned heatsinks. MSI did mATX (mostly) right this time.My youngest sons Pro 4 died after 1 month. Not a fan of either board , I would go B450.
What CPU are you going with?
