Hands-on review · Water-cooled motherboard
Verdict
The ASUS ROG Maximus IX Extreme pairs a 13-phase power section with a full Bitspower monoblock, so it suits custom water-cooled builds rather than air cooling.

Third-party reviews

What customers like about ASUS ROG Maximus IX Extreme

  • Integrated Bitspower monoblock that effectively cools the CPU, VRMs, and an M.2 SSD simultaneously.
  • Comprehensive safety features including a built-in water leak detection sensor and flow/temperature monitoring.
  • Extensive connectivity options such as built-in Thunderbolt 3, high-speed Wi-Fi (MU-MIMO), and multiple USB 3.1 ports.
  • Premium aesthetic design with synchronized Aura Sync RGB lighting and an integrated I/O shield for easier installation.
  • High-end audio performance featuring the ESS SABRE DAC and illuminated audio jacks for convenience in dark environments.
  • Robust overclocking capabilities with support for ultra-fast DDR4 memory up to 4133MHz.

What customers don't like about ASUS ROG Maximus IX Extreme

  • Extremely high price point makes it a niche product for a very small percentage of enthusiasts.
  • Mandatory custom liquid cooling requirement; the board cannot be used with standard air coolers due to the integrated monoblock design.
  • Lack of 5Gbps or 10Gbps Ethernet, which some users felt was missing given the premium 'Extreme' branding and cost.
  • The large EATX form factor may not fit in standard mid-tower cases, requiring a larger 'super tower' chassis.
  • Proprietary cooling solution means you cannot easily swap the monoblock for one from another manufacturer.

Verdict

The ASUS ROG Maximus IX Extreme is a high-end E-ATX motherboard built on the Intel Z270 chipset, supporting 6th and 7th Gen Intel Core processors via the LGA1151 socket. It features a custom-designed Bitspower monoblock that cools both the CPU and VRM, equipped with integrated flow, temperature, and leak sensors. Key specifications include four DDR4 DIMM slots supporting speeds up to 4133MHz (OC), dual M.2 slots with one integrated into the monoblock for cooling, Thunderbolt 3, 2x2 802.11ac Wi-Fi, and SupremeFX S1220 audio. Main pros include its unparalleled out-of-the-box water-cooling integration, extensive fan/pump headers (12 in total), and premium aesthetics with Aura Sync RGB. However, its significant cons include a very high price point and the lack of a PLX chip, which limits PCIe lane bandwidth for multi-GPU setups.
