For more than 10 years, ASUS motherboards have been BEST ― that’s Best-selling, Easy to use, Stable and Trusted – with over 550 million sold and most awards won. Whether you’re crafting a build for work or gaming, a diverse selection of models and innovative features make it easy to find the perfect board to suit your needs. Build your next rig with ASUS — the world’s No.1 motherboard brand.
The intuitive ASUS UEFI makes system setup a breeze. EZ Mode puts essential tools on one screen, while Advanced Mode grants total control over configuration — and there’s a built-in search feature to find options quickly. Tweak cooling parameters, save profiles, apply overclocks, and unleash the full potential of your 2nd Generation Ryzen processor.
Enthusiast systems face a diverse range of workloads. Our Fan Xpert software can be set to intelligently control system fans based upon the input of multiple sensors, including the temperature of select ASUS graphics cards — keeping your system perfectly cooled, no matter what you do.
The B450 series uses new alloy chokes that deliver higher power-conversion, lower power-dissipation and better temperature control for more efficient operation, plus high-quality thermal pads that transfer heat from the VRM array to a heatsink with ample surface area for 2nd Generation Ryzen processors.*Select models only
ROG Strix B450-E embraces a blacked-out theme with the reflective cyber-text found on other new ROG gear. With ample power for Ryzen's cores, plus storage, connectivity and cooling options for a range of hardware, ROG Strix B450-E has everything you need for budget builds up to big-league gaming rigs.
Despite diminutive Mini-ITX dimensions, ROG Strix B450-I Gaming delivers the full ROG experience for rigs with discrete or integrated graphics. It supports an army of cooling options with an onboard M.2 heatsink, fan headers and a pump for an all-in-one cooler. It also provides accelerated networking performance for online gaming with integrated 802.11ac Wi-Fi.
TUF B450-PRO Gaming represents a new approach to gaming with a distinctive, futuristic military design that truly stands apart. Featuring durable TUF Components and TUF Protection, TUF B450-PRO Gaming is designed to help new recruits build dependable and affordable rigs that run reliably from the first boot.
Prime B450M-A extends the B450 platform into content creation and everyday productivity in a microATX package. A diverse assortment of ports offers broad compatibility with a wide range of hardware, and Fan Xpert software provides fan auto-detection and temperature monitoring for CPU and GPU-intensive tasks.
