Robust power design

Stable power is crucial for maximizing the performance of Intel Core Ultra Processors (Series 2). The PRIME B860-PLUS-CSM is designed to meet the needs of high-core-count CPUs. It features 8(80A) + 1(80A) + 1(80A) + 1(80A) power stages that integrate high-side and low-side MOSFETs and drivers into packages rated for up to 80 amperes each. This configuration ensures optimal power delivery, efficiency, stability and performance for both current and future Intel processors.

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.*

*Results may vary according to individual system specifications. Currently, only 2-DIMM configurations are supported. Results are based on a test with an Intel Core Ultra 9 285K processor and 2x16GB SK Hynix DDR5-6400 Clocked Unbuffered DIMM RAM, model HMCG78AHBCA326N.

Two M.2 slots (up to 128Gbps)

PRIME B860-PLUS-CSM offers a total of three M.2 slots, including one that supports data-transfer speeds of up to 128Gbps via PCIe 5.0, one that support 64Gbps via PCIe 4.0. This enables quicker boot-up and app load times with OS or application drives.*

*Actual transmission speeds will be lower than the theoretical maximum speed.

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

The PRIME B860-PLUS-CSM motherboard offers a versatile range of connectivity, including the latest version of PCI Express, while an arsenal of USB ports includes Type-C connections expands compatibility and bandwidth even further.

USB 20Gbps port

A batch of USB ports supports high-end rigs loaded with peripherals, including a rear USB Type-C port with transmission speeds of up to 20Gbps.

Pre-mounted I/O shield

Our pre-installed I/O shield safeguards ports, simplifies the build process, increases functionality and enhances aesthetics for PC DIY enthusiasts.
