ASUS PRIME B450M-K bundkort Stik AM4 Micro ATX AMD B450
ASUS 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.
Cooler by design
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.
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
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.
USB 3.1 Gen 1 front-panel connector
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.
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.
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.
Fortified PCIe slot prevents damage
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.
Our Prime B450 Series motherboards also have strengthened solder points around both the PCIe and DIMM pins.
Pumped-up throughput, 2.5X-higher surge tolerance
ASUS LANGuard is hardware-level networking protection that employs signal-coupling technology and premium anti-EMI surface-mounted capacitors to ensure a more reliable connection and better throughput.
World-class circuit-protecting power design
An exclusive circuit design with built-in voltage regulators protects your motherboard from damage caused by unexpected high-level voltages from unstable or inferior power supplies.
Precision control for stable power
ASUS-exclusive DIGI+ VRM intelligently delivers power to the processor based on real-time demands, reducing energy waste and improving system stability.
DRAM Overcurrent Protection
Short-circuit damage prevention
Onboard resettable fuses prevent overcurrent and short-circuit damage. This extends beyond I/O ports to DRAM ― so it provides a safeguard to protect the lifespan of your system and connected devices.
Stainless-steel back I/O panel
3X corrosion-resistance for greater durability
Corrosion-resistant stainless-steel back I/O panels bonded with chromium oxide assure a lifespan that’s 3X longer than ordinary panels.
Electrostatic discharge protection
ASUS ESD Guards prolong the life of components while preventing damage from electrostatic discharge, providing protection for up to +/- 10kV of air discharge and +/- 6kV of contact discharge.
Compatible devices and components
The superior compatibility of Prime B450 Series is evidenced by our extensive list of supported devices — which includes thousands of compatible components — and our Qualified Vendor List (QVL) that identifies memory compatibility. It all adds up to more choices for worry-free PC-building experiences.
ASUS motherboards offer superb endurance. We verify this by subjecting every board to more than 8,000 hours of stringent tests. A barrage of burn-in, environmental, compatibility, software and safety tests confirm that our motherboards are exceptionally robust. It also shows that ASUS reliability surpasses industry standards, ensuring that every component is designed to function flawlessly in any environment.
