Digital Power Design

Stable power is crucial for maximising the performance of Intel Core Ultra Processors (Series 2). The PRIME B860M-K features an 6+1+1+1 phase design with discrete MOSFETs, ensuring efficient and stable power delivery for Intel processors plus steady performance for day-to-day use.

ProCool Connector

Proprietary connector augments the motherboard's link to the power supply with 8-pin connector that passes 12 volts of power directly to the processors. This connector features solid pins that can handle more current than hollow-pin connectors.

Power Saving

The Power Saving function contains several settings to easily optimise power consumption and maximise energy savings. You can enable a CPU power limit, darken Aura lighting and set the fan profile to a Power Saving mode. You can also toggle the Power Saver plan that is built into Microsoft Windows.

Digi+ VRM Control

The Digi+ voltage-regulator module (VRM) delivers real-time control over voltage droop, automatically switching frequency and power-efficiency settings.

AEMP III for Ultimate DDR5 Performance

ASUS Enhanced Memory Profile III (AEMP III) is an advanced firmware feature that empowers users to achieve unparalleled memory performance with cutting-edge CUDIMM memory. Through a two-phase comprehensive tuning process, AEMP III first optimises the clock driver and then the memory frequency. This results in the best balance between performance and stability, even at cutting-edge speeds of DDR5-7600 or higher.

DIMM Fit

DIMM Fit is an ASUS-exclusive BIOS feature that precisely analyses individual memory modules to optimise performance and pinpoint potential issues. This offers peak efficiency, compatibility, and system stability. Whether you are an overclocker seeking ultimate performance, a competitor pursuing the most responsive gameplay, or a content creator prioritising rock-solid stability, DIMM Fit provides optimisations tailored to your needs and your hardware configuration.

Two M.2 slots (up to 128Gbps)

PRIME B860M-K offers a total of two M.2 slots, including one that supports data-transfer speeds of up to 128Gbps via PCIe 5.0, one that supports 64Gbps via PCIe 4.0. This enables quicker boot-up and app load times with OS or application drives.

Cooler by Design

The PRIME B860M-K motherboard is engineered with multiple onboard heatsinks and an array of hybrid fan headers to help ensure your rig stays cool and stable under intense workloads.

VRM heatsinks and Thermal Pads
The VRM heatsinks and thermal pads improve heat transfer from the MOSFETs for better cooling performance.

Multiple Temperature Sources
Each header can dynamically reference three thermal sensors. Fan Xpert 2+ lets you to map the temperature of supported ASUS graphics cards to optimise cooling for GPU- and CPU-intensive tasks.

4-Pin PWM/DC Fan
Each onboard header supports auto-detection of PWM or DC fans.

Passive Chipset Heatsink
An aluminium passive chipset heatsink ensures optimal cooling and stable performance. It is more durable and longer-lasting than heatsinks with fans, which can be vulnerable to the build-up of dust and debris.

Smart Protection
A dedicated integrated circuit protects each fan header from overheating and excess current.

Smart Cooling Precision
ASUS Fan Xpert 2+ software provides comprehensive control over fans. An Auto-Tuning mode intelligently configures all parameters with a single click. There’s also an Extreme Quiet mode that reduces chassis fan speeds to below the default minimum to keep your system whisper-quiet when performing light tasks. Fans can also be controlled via the UEFI BIOS.

Empowering Connections

This motherboard offers a versatile range of connectivity, including support for PCIe 5.0 M.2, PCIe 4.0 slot and an arsenal of USB ports which includes Type-C connection.

Realtek 2.5Gb Ethernet
Realtek 2.5Gb Ethernet reduces CPU overhead and offers exceptionally high TCP and UDP throughput for faster, smoother data transfers.

USB 5Gbps Type-C
A batch of USB ports support high-end rigs loaded with peripherals, including a front USB Type-C connector with ultrafast USB 5Gbps for transmission speeds of up to 5Gbps.

Customisation and Personalisation

The PRIME B860M-K enhances the user experience across the board, from simplifying BIOS setting adjustments to offering customisable RGB lighting controls for a uniquely personal system aesthetic.

UEFI BIOS
The UEFI interface delivers easy-to-use configuration options for PC beginners, and advanced features for veterans.

ASUS DriverHub
Simplify driver management with automatic detection, one-click installation and update for smooth, efficient system performance.

Armoury Crate
Customise Aura Sync RGB and control ASUS devices. Includes product registration and updates.

Aura Sync
Complete RGB lighting control for enthusiast systems, ensuring seamless synchronisation with compatible hardware.

Addressable Gen2 RGB headers
Two Addressable Gen2 headers detect LED counts on compatible RGB devices, automatically adjusting lighting effects accordingly.

DIY friendly

The PRIME B860M-K motherboard features EZ PC DIY innovations that simplify and speed up the PC building process, making DIY easy and convenient.

SafeSlot Core+
SafeSlot Core+ is a one-piece stainless-steel brace that shields the slot to protect it from damage. The metal cover is tightly secured to the slot with hooks, and the entire assembly is firmly anchored to the PCB with strengthened solder points to provide a secure foundation for heavyweight graphics cards.

Q-LED Core
The Q-LED Core display produces color-coded lights during the Power-On Self-Test (POST) that can help you troubleshoot potential issues.
