Tuned to your needs
The ASUS Prime series is built on comprehensive controls. The PRIME B450M-K II includes flexible tools to tune every aspect of your system, letting you tweak performance settings to perfectly match the way you work – maximising your productivity.
All-round energy efficiency
With the Energy Processing Unit (EPU), you get system-wide power savings. The EPU automatically optimises power consumption and maximises savings in Away Mode, when your PC is not in use.
Flexible control options
Fan Xpert 2+ software provides comprehensive control over system fans. Auto-Tuning mode intelligently configures all parameters with a single click. There is also an Extreme Quiet mode, which reduces chassis fan speeds below the default minimum to keep your system whisper-quiet when performing light tasks. The fans can also be controlled via the UEFI BIOS.
Precise digital power control
The Digi+ voltage-regulator module (VRM) provides real-time control over voltage drop, automatically switching frequency and power-efficiency settings. It also lets you fine-tune your CPU for ultimate stability and performance.
Advanced tuning for serious tweakers
An intuitive Advanced mode offered via the UEFI puts you in complete control. A built-in search feature makes it easy to find options, and various advanced functions let you intelligently make nuanced adjustments so you can dial in performance just the way you want.
Quick and simple setup
EZ mode displays vital settings and stats and also offers guided wizards, drag-and-drop functionality, and a one-click application of important settings — all to help you get your rig up and running in no time.
Comprehensive cooling and protection solution
The PRIME B450M-K II motherboard is engineered with an array of hybrid fan headers and features comprehensive cooling controls that are configurable via Fan Xpert 2+ software or through the UEFI BIOS, ensuring your rig stays cool and stable under intense workloads. A VRM heatsink with thermal pads underneath improves heat transfer from the MOSFETs for better cooling performance. Each onboard CHA FAN header supports PWM and DC mode. Each header can be set to monitor and react to dedicated thermal sensors. A dedicated integrated circuit protects the fan connectors from short-circuits and overheating, among other things.
Achieve higher speeds with the onboard M.2 port
The M.2 slot supports drives up to size 22110 (22×110mm) and its PCI Express 3.0® x4 interface provides a data transfer speed of up to 32Gb/s. It offers fast data access, making it ideal for connecting an operating system or application drive.
Even the small details can make a big difference
The Prime B450M-K II series adds the subtle details that enhance every experience, from exclusive codecs that deliver pristine audio quality to an intuitive interface that lets you customise your system to create a uniquely personal look. Onboard audio features combine intelligent design and premium hardware to create a sound quality better than anything you've ever experienced. Separating the analogue/digital signal domains significantly reduces multilateral interference, a separate layer for the left and right tracks ensures minimal crosstalk between audio paths, and premium Japanese-made capacitors deliver a perfectly immersive sound signature with exceptional fidelity.
Outshine the competition with Aura Sync
A well-tuned system deserves a matching aesthetic. ASUS Aura offers full RGB lighting control with a variety of functional presets for RGB LED strips connected to the onboard RGB headers. And it can all be synchronised with an ever-expanding portfolio of Aura-capable hardware.
Armoury Crate
Armoury Crate is a new software utility that gives you centralised control of supported products. From a single intuitive interface, Armoury Crate lets you easily customise RGB lighting and effects for every compatible device in your arsenal and synchronise them with Aura Sync for unified system lighting effects. The software also provides control of settings for a select and growing number of products, including keyboard and mouse preferences. Armoury Crate even features dedicated product registration and a news area to help you stay in touch with the gaming community.
SafeSlot Core
SafeSlot Core is the ASUS-exclusive PCIe slot, featuring a special hook that anchors it more firmly to the motherboard, which provides 1.6× greater retention and 1.3× greater shear resistance than standard slots, while ASUS Prime motherboards have reinforced solder points around both the PCIe and DIMM pins. A world-class circuit-protecting power design includes built-in voltage regulators to protect your board from overvoltage from lower-quality power supplies, and onboard resettable DRAM fuses provide overcurrent and short-circuit protection, extending the life of your system and connected devices. The corrosion-resistant stainless-steel back I/O panels, bonded with chromium oxide, have a lifespan three times longer than ordinary panels, while ASUS LANGuard technology increases network throughput and provides 2.5× greater surge tolerance thanks to advanced signal-coupling technology and premium anti-EMI surface-mounted capacitors, ensuring a more reliable connection.
BIOS FLASHBACK™
BIOS Flashback™ is the easiest and safest (UEFI) BIOS update method. Simply drag the (UEFI) BIOS file onto a FAT32-formatted USB flash drive, plug it into the USB BIOS Flashback™ port and press the button. Updates can even be performed without having a memory or CPU installed.

Choosing a motherboard
When choosing a motherboard, it is important to pay particular attention to the motherboard's socket type, format, and chipset. These are among the most important parameters and ensure the board's compatibility with the processor, expansion cards, and other components. The specific socket will be used to select a suitable processor, while the remaining connectors will be used to select other components for your future computer.Specifications
