Fan Xpert 2+ - Flexible cooling controls for air or liquid

Prime B450 Series motherboards offer comprehensive control system fans, via the included Fan Xpert 2+ software. Auto-Tuing mode intelligently configures all parameters with a single click.

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 header supports auto-detection of PWM or DC fans.

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.

The UEFI BIOS is an early waypoint on any PC-building journey, and Prime B450 Series has one of the best in the business.

Q-Fan Control - 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.

Search Function - 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.

Ultrafast connectivity

USB 3.1 Gen 2 Type-A

Ultimate-speed 10Gbps with USB 3.1 Gen 2 onboard

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.

Future-proof connectivity

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.

Affordable acceleration for any hard drive

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.
