In ASUS’s words

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.

Fan Xpert 2+ software provides comprehensive control over system fans.

Auto-Tuning mode intelligently configures all parameters with a single click. There's also an Extreme Quiet mode that reduces chassis fan speeds to below the default minimum to keep your system whisper-quiet when performing light tasks. Fans can also be controlled via the UEFI BIOS.

The Digi+ voltage-regulator module (VRM) delivers real-time control over voltage droop, automatically switching frequency and power-efficiency settings.

It also allows you to fine-tune your CPU for ultimate stability and performance.
