Component for: PC, Motherboard form factor: micro ATX, Motherboard chipset family: AMDB650M-A II-CSMASUS Prime series motherboards are expertly engineered to unleash the full potential of AMD Ryzen 7000-series processors. Boasting a robust power design, comprehensive cooling solutions and intelligent tuning options, PRIME B650M-A II-CSM provides users and PC DIY builders with a range of performance optimizations via intuitive software and firmware features.
FLEXIBILITYComprehensive 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 BoostAMD 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.
COOLINGPRIME 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 PadVRM heatsink and thermal pads improve heat transfer from the MOSFETs and chokes for better cooling performance.
Cooler by DesignPrime B650 series features comprehensive cooling controls that are configurable via Fan Xpert 2+ software or via the UEFI BIOS.
Multiple Temperature SourcesEach 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.
4-Pin PWM/DC FanEach onboard header supports auto-detection of PWM or DC fans.
PERFORMANCEThe 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 EnhancementComprehensive 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 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.
