ASUS AI Advisor allows users to explore the functionality and advanced features of ASUS motherboards in a simple and straightforward way.

Digital Power Design
Stable power is crucial for maximizing 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.

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 optimizes 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 analyzes individual memory modules to optimize 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 prioritizing rock-solid stability, DIMM Fit provides optimizations 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.

ASUS Fan Xpert 2+
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.

Personalization
The PRIME B860M-K enhances the user experience across the board, from simplifying BIOS setting adjustments to offering customizable 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

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.
