Verdict

The ASUS ROG Strix Z270I Gaming is a high-performance mini-ITX motherboard featuring the Intel Z270 chipset and LGA 1151 socket, supporting 6th and 7th Gen Intel Core processors. It is equipped with two DIMM slots supporting up to 32GB of DDR4 memory overclocked to 4266MHz+, and includes standout features like dual M.2 slots (one with an innovative 'double-decker' heatsink for thermal management), integrated 2x2 802.11ac Wi-Fi with MU-MIMO, and a front-panel USB 3.1 header. Its main pros include exceptional SupremeFX S1220A audio, a robust 6+2 phase VRM for stable overclocking, and a color-neutral design with Aura Sync RGB lighting that fits various build themes. However, potential drawbacks include a premium price tag compared to its competitors, a limited number of fan headers (only three), and the absence of a dedicated internal USB 2.0 header.
