ASUS AI Advisor allows users to explore the functionality and advanced features of ASUS motherboards in a simple and straightforward way. 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. 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. Three 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. Cooler by design
The PRIME B860-PLUS-CSM 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
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. PCIe 5.0 slot
The latest processors introduce PCIe 5.0 support, doubling data transfer speeds compared to PCIe 4.0, enhancing signal integrity, and providing backward-compatible CEM connectors and support for previous PCIe versions. Personalization
The PRIME B860-PLUS-CSM 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
