PRIME B450M-K - AMD Ryzen mATX Motherboard from ASUS
ASUS Micro ATX Motherboard built on AMD AM4 SocketASUS 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.
Enhanced UEFI BIOS
EASILY FIND YOUR WAY WITH EZ AND ADVANCED MODESThe 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.
Q-Fan ControlCan 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 FunctionWhen 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.
Speed Up With Onboard M.2
Ultrafast M.2 Connectivity with 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. 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.
USB 3.1 Gen 1 and 2
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. 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.
AMD StoreMI Technology
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.
Make Your Memory Faster
Industry-leading DDR4 memory compatibility 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.
One-stop Efficient Controls
VERSATILE ENERGY PRODUCTIVITY The Energy Processing Unit (EPU) automatically amplifies power consumption and maximises savings with Away mode. The smart setting that produces an extreme energy-saving setup by shutting down unused I/O controllers, with the EPU you will appreciate system-wide power reserves.
Flexible Cooling Controls Prime B450 Series motherboards offer comprehensive control over system fans using the included Fan Expert Software. Auto-Tuning mode intelligently confirgures all parameters with a single click.
Cooler by Design
RESPONSIVE SURFACE CALIBRATION Prime B450 Series features the most comprehensive cooling controls ever, configurable via ASUS Fan Xpert software or the UEFI BIOS. 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. Each onboard CHA FAN header supports PWM and DC mode.
PCB Protection III
Solid motherboard construction and defensive technologies Prime B450 Series motherboards are engineered with industry-leading 5X Protection III, employing the finest components, excellent circuit design and exacting standards to guarantee the quality and long-term durability of your investment. That means exceptional protection and stability for your build — thanks to decades of engineering experience from the world's leading motherboard brand.
ASUS SafeSlot Protection
Protect your graphics card investment SafeSlot Core is the ASUS-exclusive PCIe® slot. Featuring a fortified design that's anchored to the motherboard by a special hook, Safeslot Core provides 1.6X-stronger retention and 1.3X-greater shearing resistance than standard expansion slots. Prime B450 Series motherboards also have strengthened solder points around both the PCIe and DIMM pins.
