Verdict

The MSI B450 Gaming Pro Carbon AC is a premium ATX motherboard featuring the AMD B450 chipset and AM4 socket, supporting up to 64GB of dual-channel DDR4 memory overclocked to 3466 MHz. It distinguishes itself with high-end characteristics including an 8+4 pin power connector for enhanced VRM performance, integrated Intel 9260 802.11ac Wi-Fi, and the Realtek ALC1220 audio codec for superior sound. Main pros include its robust thermal design with extended heatsinks, dual M.2 slots (one with M.2 Shield), and convenient BIOS Flashback+ button for easy updates without a CPU. However, notable cons include the loss of two SATA ports when using the primary M.2 slot and a somewhat limited number of USB ports on the rear I/O compared to some competitors.
