The ASUS PRIME B860M-K motherboard is designed to fully exploit the capabilities of the latest Intel® Core™ Ultra (Series 2) processors. With robust power design and comprehensive cooling solutions, it offers performance optimizations through intuitive software and firmware features.

Connectivity

Digital Power Design

Stable power supply is critical for harnessing the full performance of Intel Core Ultra (Series 2). The PRIME B860M-K features a 6+1+1+1 phase design with discrete MOSFETs, ensuring efficient and stable power delivery to Intel processors as well as stable performance for everyday use.

AEMP III for Ultimate DDR5 Performance

ASUS Enhanced Memory Profile III (AEMP III) is an advanced firmware feature that allows users to achieve unparalleled memory performance using advanced CUDIMM memory. Through a two-phase 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 top speeds of DDR5-7600 or higher.

Cooling System

The PRIME B860M-K motherboard is designed with multiple built-in coolers and a range of hybrid fan ports to ensure that your computer stays cool and stable under heavy workload.

ASUS Fan Xpert 2+

The ASUS Fan Xpert 2+ software provides full control over the fans. Auto-Tuning works intelligently and adjusts all parameters with a single click. There is also the Extreme Quiet mode, which reduces the speed of the case fans below the minimum preset value, keeping your system silent during light tasks. The fans can also be controlled through the UEFI BIOS.

Realtek 2.5Gb Ethernet

The Realtek 2.5Gb Ethernet port reduces CPU load and offers extremely high TCP and UDP performance for faster and smoother data transfer.
