Delivery Options
Economy Delivery (UK)
Business Express
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-K 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.
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 AX, 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 entry-level modules without EXPO™ memory support, we’ve got you covered. Click here to learn more about AEMP. arrow.
For those who want to fly past stock DDR5 speeds, the PRIME B650M-A AX 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.
Outstanding Audio
Combined onboard features deliver elevated audio
Intelligent design and premium hardware create audio quality unlike anything you’ve ever experienced.
THIS CHANGES EVERYTHING.
FROM THIS NEW PLATFORM, YOU CAN SEE THE FUTURE
Build your next rig with an AMD Ryzen™ 7000 Series processor and PRIME B650M-A AX to experience advanced performance. With up to 16 “Zen 4” cores and 32 threads, boost clocks of up to 5.7GHz, and 80MB cache, the AMD Ryzen™ 7000 Series keeps you ahead of the game.1
You’ll also gain access to new features for gamers with AMD Socket AM5, from the speed of DDR5 memory to the increased bandwidth of PCIe® 5.0. AMD Ryzen™ 7000 Series processors and AMD socket AM5 motherboards are unlocked for overclocking to personalize your experience. Gain even more performance when you overclock your DDR5 memory with AMD EXPO™ technology.2
