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 are 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.
• Cooler by Design
  Prime B650 series feature comprehensive cooling controls that are configurable via Fan Xpert 2+ software or via the UEFI BIOS.
• Six-Layer PCB Design
  Multiple PCB layers optimize heat management for critical components, providing more headroom to push CPUs beyond stock speeds.

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 II-CSM, 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.
• 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.
• PCIe 5.0 M.2 Support
  PRIME B650M-A II offers a total of two M.2 slots, the first one supports data-transfer speeds of up to 128Gbps via PCIe 5.0, enabling quicker boot-up and app load times with OS or application drives.
• PCIe 4.0 Slot
  Prime B650 motherboards offer PCIe 4.0 Slot connectivity for the latest GPUs. The wide bandwidth and superfast transmission speeds allow you to create feature-rich builds that can handle high loads effortlessly.
• Front USB Type-C®
  A full complement of USB ports support high-end rigs loaded with peripherals, including a front-panel USB 3.2 Gen 1 Type-C® connector that provides data transfer speeds of up to 5Gbps.
• Realtek 2.5 Gb Ethernet
  Realtek 2.5 Gb Ethernet reduces CPU overhead and offers exceptionally high TCP and UDP throughput for faster, smoother data transfers.

LANGuard

ASUS LANGuard is a hardware-level network protection feature that integrates advanced signal-coupling technology and premium anti-EMI surface-mounted capacitors to improve throughput and ensure a more reliable connection.

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.
