Flexible cooling controls
With Prime B450-PLUS motherboard you have comprehensive control over fans, water pumps, and even all-in-one (AIO) coolers?all via Fan Expert 4 Core. Whether you’re cooling with air or water, Auto-Tuning mode intelligently configures all parameters with a single click.
All-round 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.
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.
Dedicated PWM/DC header for self-contained water-cooling setup, is built right in.
4-pin PWM/DC Fan
Each onboard header supports auto-detection of PWM or DC fans.
A dedicated integrated circuit protects each fan header from over-temperature and over-current.
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.
USB 3.1 Gen 2 Type-A
With backward-compatible USB 3.1 Gen 2 Type-A, you’ll experience ultimate connection flexibility and blazing data-transfer speeds of up to 10Gbps—twice as fast as standard USB 3.1 Gen 1.
USB 3.1 Gen 1 front-panel connector
USB 3.1 Gen 1 is right where you need it, with four super-speed headers for the front panel. Experience data-transfer speeds up to 10X faster than USB 2.0 with instant plug-and-play connectivity, and avoid back-breaking contortions in the hunt for hard-to-reach rear ports.
Speed up with onboard M.2
With x4 PCI Express 3.0/2.0 bandwidth, M.2 supports up to 32Gbps data-transfer speeds. It’s the perfect choice for an operating system or application drive, providing fast access to data.
Native M.2/NVMe PCIe RAID Support
Not satisfied with single-storage device read/write speeds? Then join the fast lane and build a RAID 0 array using two PCIe storage drives to enjoy data transfers at lightning speeds.
AMD StoreMI technology is a software utility that accelerates any drive for better system responsiveness with reduced startup and software load times. It combines SSD performance with the affordability and capacity of an HDD by automatically moving frequently accessed data to dedicated SSD storage.
Built to Last
ASUS is the world’s leading motherboard brand. Our motherboards are extensively tested for compatibility with more than 1,000 components and devices, and each new model undergoes a minimum of 8,000 hours of strict validation—offering the peace of mind of knowing that your ASUS motherboard is fit for all environments and applications. Choosing ASUS is an assurance of trouble-free DIY experiences.
Separates analog/digital signal domains, significantly reducing multi-lateral interference.
Separate layer for left and right tracks
Ensures minimal crosstalk between audio paths.
Premium Japanese-made audio capacitors
