Maximus IX Extreme is ROG’s flagship Z270-based gaming motherboard tailored for water-cooling enthusiasts in pursuit of the maximum performance, and is the result of years of industry expertise. Maximus IX Extreme is packed with ROG innovations that refine traditional solutions: The Monoblock detects the flow rate of the water coolant, and has dedicated circuitry to detect both the inlet and outlet temperatures and coolant leakage. The Monoblock also integrates the neighboring M.2 heatsink for unmatched heat-dissipation to eliminate throttling — therefore improving both reliability and enabling greater performance.

Exceptional gaming innovation

  • Integrated ROG Monoblock: First ROG design Monoblock with water temp., flow rate, and water leak sensors
  • Water Cooled M.2 heat sink: Bridge the heat from the m.2 SSD to the monoblock provides the throttling free
  • USB 3.1 front connector: Advanced connection to this reversible plug-in USB 3.1 technology
  • Pre-mounted I/O shield: Better appearance and closer tolerance gives stronger protection

Unprecedented gaming experience

  • SupremeFX S1220 CODEC: High audio performance that takes gamers to the next level
  • Sonic Studio III and Sonic Radar III: Amazing sound and superb audio controls
  • AURA SYNC: Bright up your build and sync with ASUS gear
  • Dual M.2: Two M.2 that give you the fastest and best interface
