ASUS Prime B450M II Series motherboards provide the solid foundation needed for your first build, plus flexibility to grow with your ambitions. We’ve melded all the good stuff that’s packed into AMD Ryzen™ processors with essential ASUS design and engineering, so you benefit from industry-leading technologies — including automated system tuning, comprehensive cooling controls, and immersive onboard audio. When you build with an ASUS Prime B450M II Series motherboard, you build smart, easy and affordably.
Tune It Your Way
Comprehensive controls form the foundation of the ASUS Prime series. The Prime B450M II motherboard packs flexible tools to tune every aspect of your system, enabling you to tweak performance settings to perfectly match the way you work – maximizing your productivity.
All-around 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
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.
Precise Digital Power Control
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.
UEFI BIOS
The renowned ASUS UEFI BIOS provides everything you need to configure, tweak and tune your system. It offers intelligently simplified options for PC DIY beginners, as well as comprehensive features for seasoned veterans.
Advanced Tuning for Serious Tweakers
An 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 Setup
EZ 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.
Cool to the Core
Prime B450M II series is engineered with multiple onboard heatsinks and an array of hybrid fan headers to ensure your rig stays cool and stable under intense workloads.
VRM Heatsink and Thermal Pads
A VRM heatsink with underneath thermal pad improves heat transfer from the MOSFETs for better cooling performance.
Cooler by Design
Prime B450M-A II is engineered with an array of hybrid fan headers and features comprehensive cooling controls that are configurable via Fan Xpert 2+ software or via the UEFI BIOS, ensuring your rig stays cool and stable under intense workloads.
Multiple Temperature Sources
Each header can monitor and react to dedicated thermal sensors.
Smart Protection
A dedicated integrated circuit protects the fan headers, including short circuit and over temperature protections.
4-Pin PWM/DC Fan
Each onboard CHA FAN header supports PWM and DC mode.
Build on a Solid Foundation
Prime B450M II motherboard provides all the fundamentals to boost daily productivity, so your system will be ready for action with stable power, intuitive cooling and flexible transfer options.
PCIe 3.0 M.2 (up to 32 Gbps)
Achieve speed with onboard M.2
M.2 Slot supports up to 22110 and data-transfer speed up to 32Gbps via x4 PCI Express® 3.0 bandwidth. It‘s the perfect choice for an operating system or application drive, providing fast access to data.
USB 3.2 Gen 2 Type-A
Numerous USB ports support high-end rigs loaded with peripherals, including two rear-panel USB Type-A connectors with fast USB 3.2 Gen 2 connectivity for compatible cases.
Little Things Make a Big Difference
Prime B450M II series adds the nuanced details that improve every experience, from exclusive codecs that provide pristine audio quality to intuitive RGB lighting controls that let you customize your system to create a unique personal look.
Combined onboard features deliver elevated audio
Outstanding Audio
Intelligent design and premium hardware create audio quality unlike anything you’ve ever experienced.
Aura Sync
Outshine the Competition
A well-tuned enthusiast system deserves a matching aesthetic. ASUS Aura offers full RGB lighting control with a variety of functional presets for RGB LED strips connected to the onboard RGB headers. And it can all be synced with an ever-growing portfolio of Aura-capable hardware.
Armoury Crate
Armoury Crate is a new software utility designed to give you centralized control of supported products. From a single intuitive interface, Armoury Crate allows you to easily customize RGB lighting and effects for every compatible device in your arsenal. The software also provides control of settings for ASUS products, including keyboard and mouse preferences. Armoury Crate even features dedicated product registration and highlight to help you stay in touch with the ASUS community.
BIOS FLASHBACK™
BIOS FlashBack™ is the simplest and safest (UEFI) BIOS update method. Simply drop the (UEFI) BIOS file onto a FAT32 formatted USB stick, plug it into the USB BIOS FlashBack™ port and press the button. Updates can even be performed without having memory or a CPU installed.
Fortified PCIe slot prevents damage
SafeSlot Core
SafeSlot Core is the ASUS-exclusive PCIe slot. Featuring a fortified design that’s anchored to the motherboard by a special hook, SafeSlot Core provides 1.6x stronger retention and 1.3x greater shearing resistance than standard expansion slots.
ASUS Prime motherboards have strengthened solder points around both the PCIe and DIMM pins.
