Features

FLEXIBILITY

Comprehensive controls form the foundation of the ASUS PRIME series. The PRIME B650 motherboard packs flexible tools to tune every aspect of your system, enabling performance tweaks to perfectly match the way you work to maximize productivity.

  • CPU Performance Boost
    AMD Precision Boost Overdrive(PBO) pushes the CPU current and voltage budget to opportunistically increase performance. By aggressively tuning the PBO parameters, AMD's algorithm can leverage the motherboard's robust power solution to ramp up performance even higher.
  • All-Around Energy Efficiency
    The Power Saving function contains several settings can easily optimize power consumption and maximize energy savings. You can enable a CPU power limit, darken Aura lighting, and set the fan profile to a power saving mode. You can also toggle the Power Saver plan that is built into Microsoft Windows.
  • Flexible Cooling Controls
    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.
  • Precise Digital Power Control
    The Digi+ voltage-regulator module (VRM) delivers real-time control over voltage droop, automatically switching frequency and power-efficiency settings. It also allows you to fine-tune your CPU for ultimate stability and performance.

COOLING

PRIME B650 series is engineered with multiple onboard heatsinks and an array of hybrid fan headers to ensure your rig stays cool and stable under intense workloads.

  • VRM Heatsink and Thermal Pad
    VRM heatsink and thermal pads improve heat transfer from the MOSFETs and chokes for better cooling performance.
  • Six-Layer PCB Design
    Multiple PCB layers optimize heat management for critical components, providing more headroom to push CPUs beyond stock speeds.

Cooler by Design

Prime B650 series features comprehensive cooling controls that are configurable via Fan Xpert 2+ software or via the UEFI BIOS.

Multiple Temperature Sources

Each header can dynamically reference three thermal sensors. Fan Xpert 2+ allows you to map the temperature of supported ASUS graphics cards to optimize cooling for GPU- and CPU-intensive tasks.

Smart Protection

A dedicated integrated circuit protects each fan header from overheating and overcurrent.

PERFORMANCE

The PRIME B650 series is built to handle the high core counts and bandwidth demands of AMD processors. ASUS B650 motherboard provides all the fundamentals to boost daily productivity, so your system will be ready for action with stable power, intuitive cooling and flexible data transfer options.

  • DDR5 Performance Enhancement
    Comprehensive memory tuning options are the cornerstone of PRIME motherboards. With the PRIME B650M-A AX II, you can extract all of the potential out of your DDR5 modules, whether they're from an extreme-speed kit or an entry-level set that would otherwise be locked.
    For entry-level modules without EXPO™ memory support, we've got you covered.Click here to learn more about AEMP.
    For those who want to fly past stock DDR5 speeds, the PRIME B650M-A AX II is primed and ready for enthusiast-grade kits courtesy of vast AMD Extended Profiles for Overclocking (EXPO™) support. Seasoned veterans can further tweak performance via the extensive array of settings in the UEFI.
  • ASUS OptiMem II
    Revisions to the motherboard's trace routing provide the latest processors with unrestricted access to memory bandwidth. ASUS OptiMem II technology carefully maps memory signal pathways across different PCB layers to reduce vias and adds shielding zones that significantly reduce crosstalk.

CUSTOMIZATION

The PRIME B650 series adds the nuanced details that improve every experience, from exclusivecodecs that providepristine audio quality to intuitive RGB lighting controls that let you customize your system to create a uniquely personal look.

  • Outstanding Audio
    Combined onboard features deliver elevated audio Intelligent design and premium hardware create audio quality unlike anything you've ever experienced.
  • Audio Shielding
    Audio shielding ensures precision analog/digital separation and greatly reduced multi-lateral interference.
  • Dedicated Audio PCB Layers
    Separate layers for left and right tracks ensures both channels deliver consistent, equal quality.
  • Premium Audio Capacitors
    Provides warm, natural, and immersive sound with exceptional clarity and fidelity.
