ASUS Prime B450 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 B450 Series motherboard, you build smart, easy and affordably.
Cooler by design
Prime B450 Series features the most comprehensive cooling controls ever, configurable via ASUS Fan Xpert software or the UEFI BIOS.
Multiple temperature sources
Each header can be set to monitor and react to up to three thermal sensors. Via Fan Xpert, you can also assign a sensor to monitor the temperature of supported ASUS graphics cards to ensure optimal cooling during GPU- or CPU-intensive workloads.
4-pin PWM/DC fan
Each onboard CHA FAN header supports PWM and DC mode.
Make your memory faster
Featuring an array of trace layout tweaks that improve memory stability, PRIME B450 Series provides a potent foundation for your build. With comprehensive support for the full gamut of Ryzen memory configurations - from entry-level to performance-oriented - PRIME B450 Series is a versatile all-rounder that can work or play.
Media-acclaimed UEFI BIOS
The UEFI BIOS is an early waypoint on any PC-building journey, and Prime B450 Series has one of the best in the business.
Can configure the fan's operating speed manually, or use the easy pre-configured fan profiles to select Standard, Silent, Turbo or Full Speed modes, plus automatic switch to full speed if the temperature hits 75°C.
When you're ready for a deeper dive, Advanced mode enables full control over every aspect of the motherboard - with a built-in Search function to find the setting you need in the blink of an eye.
