Verdict

The ASUS ROG Strix B450-I Gaming is a high-performance Mini-ITX motherboard featuring the AMD AM4 socket and B450 chipset, supporting 1st, 2nd, and 3rd Gen Ryzen processors. Key specifications include two DIMM slots for up to 64GB of DDR4 memory (overclocked up to 3600MHz), dual M.2 slots (one with a dedicated heatsink), onboard 2x2 802.11ac Wi-Fi with MU-MIMO, and SupremeFX S1220A high-definition audio. Main pros include its innovative M.2 Audio Combo Card that saves space, robust VRMs for stable overclocking, and extensive Aura Sync RGB lighting options. However, notable cons include a lack of heatsink cooling for the SOC VRM phase, making it less ideal for APU builds, and some reported compatibility issues with USB 3.1 bandwidth.
