buying a b450 for ryzen 3600 without having an older chip

[sr.ded]

I'm looking to upgrade from an i5 6500 to ryzen 5 3600 and I don't need any of the things that only x470 or x570 have and I want an m atx form factor which is apparently dead so I'm looking into buying a mid ranged b450 mobo but I don't own or have access to an older cpu to update the bios and I don't know if it's possible to update without one or if I can get one that's already updated from amazon/newegg I can't find a pc store (idk what you call them) near since I'm in israel and I'm aware of two that know anything about the parts they sell I was thinking about the ASRock B450M PRO4 but if there is a different one can be updated without a cpu or is a better idea I'd welcome the advice

MSI B450 Tomahawk MAX. One of the best B450 boards and Ryzen 3000 ready out of the box.

isn't it an atx board? I need an m-atx board since that's the case I have and I'm happy with it and can't afford to upgrade it as well

All the B450 MSI boards that have "MAX" on them work with 3rd gen Ryzen out of the box. For Asrock, I've heard that their B450 Steel Legend series boards also support it out of the box.

Go for the MSI Mortar Max. This is the mATX equivalient of the Tomahawk.

if the B450M/AC, mortar or bazooka plus are available, then get those instead.
