EPU

 

Fan Xpert

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.

Flexible cooling controls

Prime B450 Series motherboards offer comprehensive control over system fans, via the included Fan Expert software. Auto-Tuning mode intelligently configures all parameters with a single click.

Cooler by design

Prime B450 Series features the most comprehensive cooling controls ever, configurable via ASUS Fan Xpert software or the UEFI BIOS.

Multiple temperature sources

 

4-pin PWM/DC fan

Each header can be set to monitor and react to up to three thermal sensors. Via Fan Xpert, you can also assign a sensor to monitor the temperature of supported ASUS graphics cards to ensure optimal cooling during GPU- or CPU-intensive workloads.
