Robust Power Design
A stable power supply is crucial for maximizing the performance of Intel® Core™ Ultra (Series 2) processors. The PRIME B860-PLUS-CSM is designed to meet the demands of high-core-count CPUs. It features 8 (80A) + 1 (80A) + 1 (80A) + 1 (80A) power stages, integrating high-side and low-side MOSFETs and drivers in packages capable of delivering up to 80 amps each. This configuration ensures optimal power delivery, efficiency, stability, and performance for current and future Intel® processors.

Six-layer circuit board design
The multi-layered circuit board design quickly dissipates heat around the voltage regulators to improve overall system stability and give the CPU more overclocking headroom.

Pro Cool connection
Proprietary connectors complement the connection between the motherboard and the power supply with 8-pin plugs that deliver 12 volts of power directly to the processor. Each connector features solid pins that can handle more current than hollow pins.

Saving electricity
The power saving feature includes various settings to optimize power consumption and maximize energy savings. You can enable a CPU power limit, dim the Aura lighting, and set the fan profile to a power-saving mode. You can also switch the power plan built into Microsoft Windows.

Digi+ VRM control
The Digi+ voltage regulator module (VRM) provides real-time control over voltage drop and automatically controls frequency and energy efficiency settings.

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 with the latest CUDIMM memory. Through a comprehensive two-stage tuning process, AEMP III first optimizes the clock driver and then the memory frequency. The result is an optimal balance between performance and stability, even at peak 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 identify potential issues. This delivers maximum efficiency, compatibility, and system stability. Whether you“re an overclocker seeking ultimate performance, a competitive gamer striving for the most responsive gameplay, or a content creator who values rock-solid stability, DIMM Fit provides optimizations tailored to your needs and hardware configuration.

Three M.2 slots (up to 128Gbps)
The PRIME B860-PLUS-CSM offers a total of three M.2 slots, one of which supports data transfer speeds of up to 128 Gbps via PCIe 5.0 and one of which supports 64 Gbps via PCIe 4.0. This enables faster boot and load times for operating systems and applications.

ASUS Fan Xpert 2+
ASUS Fan Xpert 2+ software offers comprehensive fan control. The Auto-Tuning mode intelligently configures all parameters with a single click. There“s also an ultra-quiet mode that reduces fan speeds below the standard minimum, ensuring your system remains whisper-quiet during light tasks. Fans can also be controlled via the UEFI BIOS.

PCIe 5.0 slot
The latest processors support PCIe 5.0, which doubles the data transfer speed compared to PCIe 4.0, improves signal integrity, and offers backward-compatible CEM connectors as well as support for earlier PCIe versions.

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

UEFI BIOS
The UEFI interface offers user-friendly configuration options for PC novices and advanced features for veterans.

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

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

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

Addressable Gen2 RGB headers
Three addressable Gen2 headers detect the number of LEDs on compatible RGB devices and automatically adjust the lighting effects.

Q-LED
The integrated Q-LED troubleshooting lights give PC users a quick indication to confirm that the main components – CPU, RAM, graphics card, storage devices – are functioning normally during the boot process.

Pre-assembled connection panel
Our pre-installed I/O shield protects the ports, simplifies assembly, increases functionality and improves aesthetics for PC DIY enthusiasts.

SafeSlot
PCIe 5.0 is twice as fast as PCIe 4.0. ASUS has adapted our SMT manufacturing process for the faster SafeSlot, a reinforced metal casing that ensures secure card installation and higher data speeds.
