They don't impact AM4 connectors, only AM5. If you're just powering on D.O.C.P and possibly Precision Boost Overdrive, either unit should function. In that scenario, choose the more affordable option. Reminder: I favor MSI BIOS setup for overclocking, though the pro4 model offers marginally superior components if you prioritize that.
Issues with MSI on AM4 mainly stem from the B550’s performance under high memory usage, especially above 4000 MHz. If you plan to run desync FCLK or an APU, an MSI B550M isn’t ideal. Prices for both new and used B450s are generally lower than B550s, with only minor differences like PCIe 3 versus PCIe 4 relevance unless you require NVMe for gaming.
