To add to the point above: honestly I gotta disagree slightly on the budget boards for such a beastly CPU! That 5900X has 12 cores and can pull a ton of current, so you really want something with rock-solid VRMs to avoid any thermal throttling. Im obsessed with the X570S refreshes because theyre silent and super efficient! Check these out:

• MSI MAG X570S Tomahawk Max WiFi with its 12+2+1 power stages
• Gigabyte X570S Aorus Master for that insane 14 phase digital VRM The Tomahawk is basically the sweet spot for value and performance. Seriously, dont skimp on the power delivery for a high-end Ryzen chip or youll regret it when those clock speeds start dipping... stick with the newer S models for the best experience!

TUF Gaming X570-Plus (Wi-Fi) is a good budget motherboard for 5900X.

ASUS ROG Dark HERO.

Any B550 motherboard are OK.
