Verdict

The Asus TUF Gaming B450M-PRO S is a micro-ATX motherboard designed for AMD AM4 socket processors, including the Ryzen 5000 series via BIOS update. It features an upgraded 8+2 DrMOS power stage design with ProCool connectors for improved power delivery and a robust cooling solution that includes enlarged VRM heatsinks and an M.2 heatsink. Key specifications include support for up to 128GB of DDR4 memory at speeds reaching 4400MHz (OC), dual M.2 slots (one PCIe 3.0 x4, one PCIe 2.0 x4), 2.5 Gb Ethernet, and high-quality Realtek S1200A audio. Notable pros include its excellent VRM performance for its class, 2.5G LAN, and BIOS FlashBack functionality for easy CPU compatibility updates. However, cons include limited PCIe 2.0 speeds on the secondary M.2 slot and potential thermal limits when paired with high-draw Ryzen 9 CPUs under heavy overclocking.
