All-around energy efficiency
Precise digital power control
Advanced tuning for serious tweakers
Quick and simple setup
M.2 heatsink
Multiple temperature sources
All-around energy efficiencyThe Energy Processing Unit (EPU) automatically optimizes power consumption and maximizes energy savings with Away mode - a smart setting that creates an extreme energy-saving scenario by shutting down unused I/O controllers.Precise digital power controlThe 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.Advanced tuning for serious tweakersAn intuitive Advanced mode offered via the UEFI lets you take complete control. A built-in search feature makes it easy to find options, and various advanced functions let you intelligently make nuanced adjustments so you can dial in performance just the way you want.Quick and simple setupEZ mode displays vital settings and stats and also offers guided wizards, drag-and-drop functionality, and one-click application of important settings - all to help you get your rig up and running in no time.M.2 heatsinkM.2 heatsink wards off throttling that can occur with M.2 storage during sustained transfers. The heatsink is held in place by captive screws.Multiple temperature sourcesEach header can dynamically reference three thermal sensors. Fan Xpert 2+ allows you to map the temperature of supported ASUS graphics cards to optimize cooling for GPU- and CPU-intensive tasks.
