When you build with an ASUS Prime B450 Series motherboard, you build smart, easy and affordably.
Tune it your way

Cooler by design
Prime B450 Series features the most comprehensive cooling controls ever, configurable via ASUS Fan Xpert software or the UEFI BIOS.
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.
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 

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 two 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.
Native M.2/NVMe PCIe RAID Support for Lightning Fast Storage Speed!
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.
