Increased performance and energy saving
AMD Precision Boost Overdrive (PBO) increases the CPU's current and voltage to achieve higher performance when needed, and by aggressively tuning parameters, it can leverage the motherboard's robust power delivery for even greater performance gains. The Power Saving function offers several settings for easy power consumption optimisation, such as limiting CPU power, dimming Aura lighting, setting the fan profile to an energy-saving mode, or switching the integrated power plan in Microsoft Windows.
Flexible cooling and precise power delivery
ASUS Fan Xpert 2+ software provides comprehensive control over your fans, enables automatic tuning of all parameters with a single click, offers an extremely quiet mode with minimal RPM for light tasks, and can be controlled via the UEFI BIOS. The Digi+ voltage-regulator module (VRM) provides real-time control over voltage drop, automatically switching frequency and power efficiency settings, and lets you fine-tune your CPU for ultimate stability and performance.
UEFI BIOS for easy and advanced tuning
The renowned ASUS UEFI BIOS offers an intuitive EZ mode with an overview of key settings, a wizard, drag-and-drop functionality, and one-click application of essential options, while the Advanced mode provides full control, a search function, intelligent fine-tuning, and an ASUS user profile for transferring and sharing configurations. It also includes graphical fan control by dragging a curve with the mouse and an Aura On/Off mode for easy control of RGB lighting or onboard LEDs.
Advanced cooling for stable performance
The Prime B650 series of motherboards is equipped with onboard heatsinks and hybrid fan headers to ensure stable operation even under heavy loads. The VRM heatsink with thermal pads improves heat transfer from the MOSFETs and chokes, while comprehensive cooling control can be configured via Fan Xpert 2+ or the UEFI BIOS. Each header supports up to three thermal sensors, can map the temperature of ASUS graphics cards, has protection against overheating and overcurrent, and automatically detects PWM or DC fans. The Stack Cool 3+ two-ounce copper layer then effectively dissipates heat from key components to maintain optimal operating temperatures.
Performance and readiness of the PRIME B650 motherboard
The PRIME B650 series is built to handle the high core counts and bandwidth demands of AMD processors. The ASUS B650 motherboard offers all the essentials to boost daily productivity. Your system will be ready for action with stable power, intuitive cooling and flexible data transfer options. A key attribute of PRIME motherboards is their comprehensive memory tuning features. With the PRIME B650M-R board, you can unlock the full potential of your DDR5 modules, whether they're from an extreme-speed kit or an entry-level set that would otherwise be locked.
Fast storage and reliable connectivity
The PRIME B650M-R motherboard offers two M.2 slots with data transfer speeds of up to 64Gb/s via PCIe 4.0 for faster system boot and application load times, a PCIe 4.0 slot for connecting modern graphics cards, a wide range of USB ports including a front-panel USB Type-C® with speeds of 5Gb/s, and a Realtek 2.5Gb Ethernet solution with reduced CPU overhead and high throughput. Additionally, the ASUS LANGuard feature provides protection against electromagnetic interference and ensures a more reliable connection.
Premium audio technology
The combination of onboard features and quality hardware delivers an exceptional audio experience, where audio shielding minimises interference, dedicated audio PCB layers maintain consistent quality for the left and right channels, and premium capacitors provide warm, natural, and immersive sound with high clarity and fidelity.
Aura Sync and AI noise cancellation
ASUS Aura offers complete RGB lighting control with a wide range of effects for onboard LEDs, connected strips, or devices, all of which can be synchronised with an extensive portfolio of Aura-compatible hardware. Two addressable Gen 2 headers can detect the number of LEDs and automatically tailor lighting effects to specific devices, while also ensuring backward compatibility with existing RGB gear. The two-way AI noise-cancellation feature uses a massive deep-learning database to remove distracting noises from the microphone and incoming audio, such as mouse clicks or keyboard clatter, preserving clear vocals with minimal impact on performance.
Armoury Crate
Within a single intuitive interface, Armoury Crate offers easily customisable Aura Sync RGB settings for every compatible device in your arsenal, plus controls for the ever-expanding family of ASUS products, including keyboard and mouse presets. Armoury Crate also integrates product registration and a news feed, so you’ll never miss out on updates relevant to the ASUS community.
Q-LED Core and BIOS FlashBack™
The PRIME B650M-R motherboard is equipped with a Q-LED Core display, which uses LED light patterns during the POST test to help diagnose problems – a fast flash indicates an undetected CPU, a slow flash indicates a missing VGA, a very slow flash indicates an undetected boot device, and a steady light means the installation is complete. The BIOS FlashBack™ feature enables easy and safe BIOS (UEFI) updates via a USB drive, even without memory or a processor installed.
Durability and component protection
ASUS's exclusive SafeSlot Core PCIe slot features a reinforced design anchored by a special hook, which provides a 1.6× stronger hold and 1.3× greater shear resistance than standard slots. The motherboard is also protected by an overvoltage protection circuit with built-in voltage regulators, and the stainless steel back I/O panel with a chromium-oxide finish provides three times the corrosion resistance for a longer lifespan.

Choosing a motherboard
When choosing a motherboard (or mainboard), it is important to pay close attention to the socket type, form factor, and chipset. These are among the most crucial parameters, ensuring the board's compatibility with the processor, expansion cards, and other components. The specific socket will determine the choice of a suitable processor, while the remaining connectors will dictate the selection of other components for your future computer.Specifications
