Robust power and AI features
The motherboard uses a 10+2+1 power solution rated at 90A per phase with a ProCool power connector. AI Cache Boost increases the performance of large language models by optimising the CPU cache and memory channels, delivering up to 29% higher performance for local LLMs. ASUS AI Advisor uses AI to understand natural language questions, enabling users to explore the features and advanced capabilities of ASUS motherboards. AI Networking II combines technologies that optimise network performance, provide a reliable connection, and unlock the speed of WiFi 7. DIMM Fit performs a precise analysis of individual memory modules to optimise performance and identify potential issues.
Advanced overclocking and cooling features
The Dynamic OC Switcher maximises processor performance and lets you set current and temperature thresholds to automatically switch between manual overclocking for demanding multi-threaded tasks and Precision Boost Overdrive for single-threaded tasks. Core Flex allows you to control clocks, power, and temperatures in creative ways, supporting several user-controlled features that can independently adjust power, current, and temperature limits. PBO Enhancement aggressively tunes PBO parameters, using the motherboard's robust power solution to achieve higher performance gains. The board is equipped with a VRM heatsink, M.2 and chipset heatsinks, high-conductivity thermal pads, and headers for CPU, pump, and chassis fans with higher airflow. The board takes full advantage of the modern standard and offers comprehensive PCIe 5.0 support.
Personalisation and DIY friendliness
The BIOS Q-Dashboard simplifies motherboard configuration with a visual display of hardware connections and corresponding BIOS settings. The innovative M.2 Q-Slide and M.2 Q-LATCH make installing storage devices easier. PCIe Slot Q-Release Slim simplifies the removal of graphics cards. Q-Antenna makes it easy to connect the WiFi antenna. TurboV Core software enables overclocking in Windows without the BIOS interface and without restarts. The Clear CMOS button and BIOS FlashBack button make operation easier. Armoury Crate software centralises control of supported gaming products and includes ASUS Fan Xpert 4 for comprehensive fan control. ASUS GlideX enables screen sharing and control, and operation across devices and platforms.

Choosing a motherboard
When choosing a motherboard, it's important to pay close attention to the socket type, form factor, and chipset. These are the most critical parameters and ensure the board is compatible with the processor, expansion cards, and other components. The specific socket determines your choice of processor, while the other connectors dictate which additional components you'll need for your future PC.Specifications
