Enhanced UEFI BIOS
EASILY FIND YOUR WAY WITH EZ AND ADVANCED MODES
The UEFI BIOS is an early waypoint on any PC-building journey, and Prime B450 Series has one of the best in the business. The EZ mode makes it incredible easy to overclock a CPU to improve performance or even configure a RAID array for faster data retrieval and backups. Whether you're a PC novice or a seasoned overclocker, EZ and Advanced modes will help you quickly find your way, quickly and easily.
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.
ASUS Aura Sync RGB Lighting
BRIGHTEN YOUR BUILD
A well-tuned enthusiast system deserves a matching aesthetic. ASUS Aura Sync offers full lighting connected via the motherboard's RGB header, with a variety of functional presets for external LED strips. And it can all be synced with an ever-growing portfolio of Aura-capable ASUS hardware.
Speed Up With Onboard M.2
ULTRAFAST M.2 CONNECTIVITY WITH RAID SUPPORT
An impeccable choice for an operating system or application drive, providing rapid access to data. Speed up with on-board M.2 with x4 PCI Express 3.0/2.0 bandwidth. M.2 supports up to 32Gbps data-transfer speeds. 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.
USB 3.1 Gen 1 and 2
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. 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.
