PRIME B450M-A II
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.
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.
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.
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.
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.
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.
