Asus Prime B450M-A II Socket AM4 - Motherboard

ASUS Prime B450 II series motherboards provide a solid foundation for building your first computer and the flexibility you need when your ambitions grow. This series of motherboards combines the best of AMD Ryzen processors with exclusive ASUS technologies including automatic system tuning, advanced cooling controls, and immersive integrated sound. Assemble your equipment simply and intelligently with the ASUS Prime B450 series.

ADJUST IT AS YOU WANT
Comprehensive controls form the foundation of the ASUS Prime series. The Prime B450M II motherboard includes flexible tools to fine-tune every aspect of your system, allowing you to fine-tune performance settings to perfectly fit the way you work, maximizing productivity.

Comprehensive energy efficiency
With the Energy Processing Unit (EPU), you'll enjoy system-wide energy savings.

Flexible cooling controls
Fan Xpert 2+ software provides complete control over system fans. Auto-Tuning mode intelligently configures all parameters with a single click. There's also an Extremely Quiet mode that reduces the chassis fan speed below the default minimum to keep your system quiet when performing light tasks. The fans can also be controlled via UEFI BIOS.

Precise digital power control
The Digi+ Voltage Regulator Module (VRM) offers real-time control over voltage drop, automatically changing frequency and energy efficiency settings. It also allows you to tune your CPU for maximum stability and performance.

UEFI BIOS
The renowned ASUS UEFI BIOS offers everything you need to configure and tune your system. It offers cleverly simplified options for PC DIY beginners, as well as comprehensive features for seasoned veterans.

REFRIGERATION
The Prime B450M II Series is designed with multiple integrated heatsinks and a variety of hybrid fan headers to ensure your rig stays cool and stable under intense workloads.

VRM heatsink and thermal pads
A VRM heatsink with thermal pad underneath improves heat transfer from the MOSFETs for better cooling performance.

Cooler by design
Prime B450M-A II is designed with a variety of hybrid fan headers and features comprehensive cooling controls that can be configured via the Fan Xpert 2+ software or via the UEFI BIOS, ensuring your rig stays cool and stable under intense workloads.

BUILD ON A SOLID FOUNDATION
The Prime B450M II motherboard provides all the fundamentals to drive everyday productivity, so your system will be ready for action with stable power, intuitive cooling, and flexible transfer options.

PCIe 3.0 M.2
The M.2 slot supports up to 22110 and up to 32Gbps data transfer speed over x4 PCI Express 3.0 bandwidth. It is the perfect choice for an operating system or application drive as it provides quick access to data.

USB 3.2 Gen 2 Type A
Numerous USB ports support high-end equipment loaded with peripherals, including two USB Type-A connectors on the rear panel with fast USB 3.2 Gen 2 connectivity for compatible chassis.

THE LITTLE THINGS MAKE A BIG DIFFERENCE
The Prime B450M II Series adds the nuanced details that enhance every experience, from exclusive codecs that deliver pristine audio quality to intuitive RGB lighting controls that let you customize your system to create a uniquely personal look.

Exceptional Audio
Smart design and premium hardware create audio quality unlike any you've ever experienced.

AuraSync
A well-tuned system deserves an aesthetic to match. ASUS Aura offers complete RGB lighting control with a variety of functional presets for RGB LED strips connected to the integrated RGB headers. And it can all be synced with a growing portfolio of Aura-compatible hardware.

Armory Crate
Armory Crate is a new software utility designed to give you centralized control of supported products. From a single intuitive interface, Armory Crate allows you to easily customize lighting and RGB effects for every compatible device in your arsenal. The software also provides control of settings for ASUS products, including keyboard and mouse preferences. Armory Crate even features dedicated and highlighted product registration to help you stay in touch with the ASUS community.

BIOS FLASHBACK
BIOS FlashBack is the simplest and safest BIOS update method (UEFI). Simply place the BIOS (UEFI) file on a FAT32 formatted USB stick, plug it into the USB BIOS FlashBack port and press the button. Updates can be performed even without memory or CPU installed.

SafeSlot Core
SafeSlot Core is ASUS' exclusive PCIe slot. With a reinforced design that is anchored to the motherboard by a special hook, SafeSlot Core provides 1.6 times stronger retention and 1.3 times greater cut resistance than standard expansion slots.
