ASUS 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 AX provides users and PC DIY builders with a range of performance optimizations via intuitive software and firmware 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.
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.
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 four 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.
