ASUS ROG B450 II Motherboard

Comprehensive Cooling

Cooler through Refinements

New alloy chokes with higher power conversion, lower power dissipation and better temperature control offer more efficient performance. ASUS B450 II series motherboards also feature high-quality thermal pads to effectively transfer heat from the VRM array to a large, high-surface-area heatsink.

Fan Xpert

Fan Expert 4 provides comprehensive control over fans, water pumps and all-in-one (AIO) coolers. Control is also possible via the award-winning ASUS 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.

Build Smart

BIOS FlashBack™

To easily update the UEFI (BIOS), users can plug a FAT32-formatted USB drive with the new BIOS file into the USB BIOS FlashBack port and simply press a button. Updates can be made even if memory and a processor aren’t present.

Media-Acclaimed UEFI BIOS

The renowned ASUS UEFI (BIOS) provides everything needed to configure, tweak and tune builds. It offers simplified options for newcomers to PC DIY, as well as comprehensive features for seasoned builders. ASUS B450 II series includes 256 MB BIOS Flash ROM for future-proof compatibility.

AI NOISE-CANCELING

MICROPHONE

AI noise-canceling microphone software is exclusively featured on ASUS motherboards and supports 3.5 mm*, USB, or Bluetooth headsets. The utility leverages a massive deep-learning database to preserve the sound of your voice while eliminating distracting keyboard clatter, mouse clicks, and other forms of environmental noise. And it only places a slight load on the CPU, ensuring minimal impact on gaming performance.

*An audio splitter (3.5 mm audio jack Y-cable) is necessary when using a 3.5 mm headset.
