• AMD AM5 socket - ready for AMD Ryzen 7000 Series desktop processors
• Ultrafast connectivity - M.2 PCIe 5.0, Realtek 2.5 Gb Ethernet, USB 3.2 Gen 2 ports, front USB 3.2 Gen 1 Type-C
• ASUS OptiMem II - careful routing of traces and vias, plus ground layer optimizations to preserve signal integrity for improved memory overclocking
• Comprehensive cooling - VRM heatsink, PCH heatsink, hybrid fan headers
• Aura Sync RGB lighting - onboard addressable Gen 2 headers and Aura RGB header for RGB LED strips, easily synced with Aura Sync-capable hardware

• 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.
• 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.
• 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.
• 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 128 Gbps 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.
