Asrock B450 Steel Legend performs well with 3700X.
Hello, your recent purchase of the Asus Prime Plus B450 motherboard for your Ryzen 7 3700X didn’t quite meet expectations. It appears it won’t fully utilize the chipset’s potential and might be too demanding on the VRMs. You’ve already ordered an MSI X470 Gaming Plus as a replacement, but it’s currently unavailable. The stock is limited to B450 or B550 models. I assume the “X” series chipsets are for higher-end builds—yes, that’s correct. The B450 board should work well with your 3700X, while the B550 offers more features if you need extra performance. The Asrock B450 Steel Legend is a solid choice as a compatible replacement. Let me know if you’d like more details!
It's the same motherboard tier, but age still plays a role. B550 boards support PCIe Gen 4 in the main x16 and M.2 slots, plus Gen 3 elsewhere. B450 is older—only Gen 3 for the main slot and Gen 2 afterward. The rear connectivity on B550 tends to be superior, offering 10Gbps USB ports and 2.5G Ethernet. IO specs differ by model, so verify your specific board's capabilities. While it might not be crucial, these upgrades can count for many users.
