Tuned to your needs
The ASUS Prime series is built on comprehensive controls. The Prime B450 includes flexible tools to tune every aspect of your system, letting you adjust performance settings to perfectly match the way you work and maximise your productivity.
All-round energy efficiency
With the Energy Processing Unit (EPU), you get system-wide power savings. The EPU automatically optimises power consumption and maximises savings in Away Mode.
Flexible control options
Fan Xpert 2+ software provides comprehensive control over your system fans. Auto-Tuning mode intelligently configures all parameters with a single click. There is also an Extreme Quiet mode, which reduces chassis fan speeds below the default minimum to keep your system whisper-quiet when performing light tasks. Fans can also be controlled via the UEFI BIOS.
Precise digital voltage control
The Digi+ voltage-regulator module (VRM) delivers real-time control over voltage droop, automatically switching frequency and power-efficiency settings. It also lets you fine-tune your CPU for ultimate stability and performance.
Advanced tuning for serious tweakers
The intuitive Advanced Mode offered via the UEFI puts you in complete control. A built-in search function 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 setup
EZ Mode displays vital settings and stats and also offers guided wizards, drag-and-drop functionality, and a one-click application of important settings—all to help you get your rig up and running in no time.
Comprehensive cooling and motherboard protection
The Prime B450M-A II motherboard is engineered with an array of hybrid fan headers and features comprehensive cooling controls that are configurable via Fan Xpert 2+ software or through the UEFI BIOS, ensuring your rig stays cool and stable under intense workloads. A VRM heatsink with thermal pads underneath improves heat transfer from the MOSFETs for better cooling performance. Each onboard CHA FAN header supports both PWM and DC mode. Every header can be set to monitor and react to dedicated thermal sensors. A dedicated integrated circuit protects each fan header from overheating and overcurrent.
Achieve faster speeds with an onboard M.2 port
The M.2 slot supports drives up to size 22110 and its PCI Express 3.0® x4 interface enables data-transfer speeds of up to 32Gb/s. It provides fast data access, making it an excellent choice for an operating system or application drive.
Little things make a big difference
The Prime B450M II series adds the nuanced details that improve every experience, from exclusive codecs that provide pristine audio quality to an intuitive interface that lets you customise your system to create a uniquely personal look. Onboard features combine for elevated audio, with intelligent design and premium hardware creating a sound quality unlike anything you've ever experienced. Shielding separates analogue/digital signal domains, significantly reducing multi-lateral interference, a separate layer for left and right tracks ensures minimal crosstalk between audio paths, and premium Japanese-made capacitors provide an immersive sound signature with exceptional fidelity.
Outshine the competition with Aura Sync
A fine-tuned system deserves an equally impressive aesthetic. ASUS Aura offers full RGB lighting control with a range of functional presets for RGB LED strips connected to the onboard RGB headers. All of this can be synchronised with an ever-expanding portfolio of Aura-compatible hardware.
Armoury Crate
Armoury Crate is a new software utility that gives you centralised control over supported products. Through a single intuitive interface, Armoury Crate lets you easily customise RGB lighting and effects for every compatible device in your arsenal and synchronise them with Aura Sync for unified lighting effects. The software also provides control over settings for a select and growing number of products, including keyboard and mouse preferences. Armoury Crate even includes a dedicated product registration and news area to help you stay in touch with the gaming community.
BIOS Flashback™
BIOS Flashback™ is the easiest and safest (UEFI) BIOS update method. Simply drag and drop the (UEFI) BIOS file onto a FAT32-formatted USB flash drive, plug it into the USB BIOS Flashback™ port and press the button. You can even perform updates without memory or a CPU installed.

Choosing a motherboard
When choosing a motherboard, it is important to pay particular attention to the motherboard socket type, format, and chipset. These parameters are among the most important and ensure the board's compatibility with the processor, expansion cards, and other components. The specific socket will determine your choice of a suitable processor, while the remaining connectors will dictate which other components you need for your future computer.Specifications
