I'm thinking about building a PC with a Ryzen 5 3600, but I really don't want to spend that much on a mobo and it seems the only ones that don't require a bios update to accommodate the 3600 are x570 boards. At least according to PCPartPicker. I also want a Micro ATX board but there aren't too many available within my price range. So I want to ask, are there any B450 boards or the like that are compatible with the Ryzen 5 3600 straight out of the box, no bios update? Any feedback would be much appreciated. Thanks.
