    All-round energy efficiency

    With the Energy Processing Unit (EPU) you'll enjoy system-wide power savings. The EPU automatically optimizes power consumption and maximizes savings with Away mode — a smart setting that creates an extreme energy-saving scenario by shutting down unused I/O controllers.

    Flexible cooling controls for air or liquid

    With Prime X299-A you have comprehensive control over fans, water pumps and even all-in-one (AIO) coolers, via either Fan Expert 4 or our award-winning UEFI. Whether you're cooling with air or water, Auto-Tuning mode intelligently configures all parameters with a single click. There's also an Extreme Quiet mode, which reduces all fan speeds to below the default minimum — keeping your system whisper-quiet when performing light tasks.

    Precise digital power control

    Digi+ delivers real-time control over voltage droop, switching frequency and power -efficiency settings, allowing you to fine-tune CPU voltage regulation for ultimate stability and performance.

    Optimize per-core performance for every app

    Intel's latest processors feature per-core tuning, and the ASUS Turbo Core app makes use of this feature by enabling you to assign applications to specific processor cores, allowing you to prioritize compute power where it's needed most.
