FLEXIBILITY
Comprehensive controls form the foundation of the ASUS PRIME series. The PRIME B650 motherboard includes flexible tools for fine-tuning every aspect of your system, allowing performance settings to be perfectly tailored to the way you work to maximize productivity.
Increase CPU performance
AMD Precision Boost Overdrive (PBO) pushes the CPU's current and voltage budget to opportunistically boost performance. By aggressively tuning PBO parameters, AMD's algorithm can take advantage of the motherboard's robust power solution to further boost performance.
Comprehensive energy efficiency
The Power Saving feature contains several settings that can easily 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 toggle the power-saving plan built into Microsoft Windows.
Flexible cooling controls
ASUS Fan Xpert 2+ software provides complete control over the 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 below the default minimum to keep your system quiet when performing light tasks. The fans can also be controlled via the UEFI BIOS.
Precise digital power control
The Digi+ Voltage Regulator Module (VRM) provides real-time control over voltage drop, automatically changing frequency and power efficiency settings. It also allows you to fine-tune your CPU for maximum stability and performance.
COOLING
The PRIME B650 series is designed with multiple integrated heatsinks and a variety 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 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.
Stack Awesome 3+
2-ounce copper layers draw heat away from critical components to keep them at their optimal operating temperatures and provide more headroom to push CPUs beyond stock speeds.
Cooler by design
The Prime B650 series features comprehensive cooling controls that can be configured via Fan Xpert 2+ software or through the UEFI BIOS.
Multiple temperature sources
Each header can dynamically reference three thermal sensors. Fan Xpert 2+ allows you to map the temperature of compatible ASUS graphics cards to optimize cooling for GPU and CPU intensive tasks.
Smart protection
A dedicated IC protects each fan header against overheating and overcurrent.
4-pin PWM/DC fan
Each onboard header supports auto-detection of PWM or DC fans.
PERFORMANCE
The PRIME B650 series is designed to handle the high core count and bandwidth demands of AMD processors. The ASUS B650 motherboard provides all the essentials to boost everyday productivity, so your system will be ready for action with stable power, intuitive cooling and flexible data transfer options.
DDR5 Performance Improvement
Comprehensive memory tuning options are the cornerstone of PRIME motherboards. With the PRIME B650M-A WIFI II, you can extract the full potential of your DDR5 modules, whether it’s an extreme speed kit or an otherwise locked entry-level set.
For entry-level modules without EXPO™ memory support, we've got you covered.
For those who want to soar beyond standard DDR5 speeds, the PRIME B650M-A WIFI II is primed and ready for enthusiast-grade kits courtesy of extensive support for AMD Extended Profiles for Overclocking (EXPO™). Seasoned veterans can further fine-tune performance via the wide range of settings in UEFI.
ASUS OptiMemII
Revisions to motherboard trace routing give the latest processors unrestricted access to memory bandwidth. ASUS OptiMem II technology carefully maps memory signal paths across different PCB layers to reduce vias and adds shielding zones that significantly reduce crosstalk.
ASUS OptiMem II Benefits:
- Improved stability and memory compatibility
- Enables lower memory latencies at equivalent voltages
- Improved memory frequency margin
PCIe 5.0 M.2 support
PRIME B650M-A WIFI II offers a total of two M.2 slots, the first supporting data transfer speeds of up to 128Gbps via PCIe 5.0, enabling faster boot and application loading times with OS or app drives.
PCIe 4.0 slot
Prime B650 motherboards offer PCIe 4.0 slot connectivity for the latest GPUs. Ample bandwidth and ultra-fast transmission speeds allow you to create feature-rich builds that can handle heavy loads effortlessly.
Front USB Type-C®
A full complement of USB ports supports high-end PCs loaded with peripherals, including a front-panel USB 3.2 Gen 1 Type-C ® connector that provides data transfer speeds of up to 5 Gbps.
Wi-Fi 6
The WiFi 6 module supports the 802.11ax standard and boosts the theoretical maximum bandwidth up to an incredible 1.2Gbps. Perhaps more importantly for power users, it’s optimized for more efficient operation on congested networks with lots of competitive traffic. Pair your motherboard with ASUS WiFi 6 routers to fully experience the networking potential of WiFi 6.
Realtek 2.5Gb Ethernet
Realtek 2.5Gb Ethernet reduces CPU overhead and delivers 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-mount capacitors to improve performance and ensure a more reliable connection.
PERSONALIZATION
The PRIME B650 Series adds the nuanced details that enhance every experience, from exclusive codecs that deliver pristine audio quality to intuitive RGB lighting controls that let you customize your system to create a uniquely personal look.
Exceptional audio
Combined integrated features deliver elevated audio
Intelligent design and premium hardware create audio quality unlike anything you’ve ever experienced.
