Verdict

The ASUS ROG Maximus IX Formula is a high-end ATX motherboard featuring the Intel Z270 chipset and LGA1151 socket, supporting 6th and 7th Gen Intel Core processors. It is defined by its integrated CrossChill EK II hybrid cooling block, allowing users to choose between air or liquid cooling for the VRMs, and includes dual M.2 slots (one vertical), onboard 2x2 802.11ac Wi-Fi, and SupremeFX S1220 audio. Main pros include its premium ROG Armor aesthetics with Aura Sync RGB lighting, a pre-mounted I/O shield for easier installation, and extensive water-cooling headers for monitoring flow and temperature. However, it comes with a high premium price tag, lacks U.2 or SATA Express ports, and its substantial weight and shrouding may interfere with some large air coolers or compact cases.
