ASUS Prime series is expertly engineered to unleash the full potential of AMD Ryzen platform. Boasting a robust power design, comprehensive cooling solutions and intelligent tuning options, Prime A520 series motherboards provide daily users and DIY PC builders a range of performance tuning options via intuitive software and firmware features.
Comprehensive controls form the foundation of the ASUS Prime series. The Prime A520 motherboard packs flexible tools to tune every aspect of your system, enabling you to tweak performance settings to perfectly match the way you work – maximizing your productivity.
With the Energy Processing Unit (EPU), you'll enjoy system-wide power savings. The EPU automatically optimizes power consumption and maximizes savings with Away mode.
Fan Xpert 2+ software provides comprehensive control over system fans. Auto-Tuning mode intelligently configures all parameters with a single click. There's also an Extreme Quiet mode that reduces chassis fan speeds to below the default minimum to keep your system whisper-quiet when performing light tasks. Fans can also be controlled via the UEFI BIOS.
The Digi+ voltage-regulator module (VRM) delivers real-time control over voltage droop, automatically switching frequency and power-efficiency settings. It also allows you to fine-tune your CPU for ultimate stability and performance.
*Specifications vary by models.
The renowned ASUS UEFI BIOS provides everything you need to configure, tweak and tune your system. It offers intelligently simplified options for PC DIY beginners, as well as comprehensive features for seasoned veterans.
An intuitive Advanced mode offered via the UEFI lets you take complete control. A built-in search feature makes it easy to find options, and various Advanced functions let you intelligently make nuanced adjustments so you can dial in performance just the way you want.

PRIME A520M-A II is engineered with multiple onboard heatsinks and an array of hybrid fan headers to ensure your rig stays cool and stable under intense workloads.
A VRM heatsink with underneath thermal pad improves heat transfer from the MOSFETs for better cooling performance.
Two massive VRM heatsinks with underneath thermal pads improve heat transfer from the MOSFETs and chokes for better cooling performance. A bundled fan holder provides additional cooling options.
2oz-copper layers shift heat away from critical components, reducing the temperature by up to 20°C.
Prime A520M-A II is engineered with an array of hybrid fan headers and features comprehensive cooling controls that are configurable via Fan Xpert 2+ software or via the UEFI BIOS, ensuring your rig stays cool and stable under intense workloads.
Each header can monitor and react to dedicated thermal sensors.
A dedicated integrated circuit protects the fan headers, including short circuit and over temperature protections.
Each onboard CHA FAN header supports PWM and DC mode.
Prime A520 motherboard provides all the fundamentals to boost daily productivity, so your system will be ready for action with stable power, intuitive cooling and flexible transfer options.
Stable power is essential to extract every last bit of performance out of 10th Generation Intel Core processors, Prime A520 is geared to cater to the demands of these high-core count CPUs.
Proprietary connectors augment the motherboard's link to the PSU with 8+4 pin connectors that pass 12 volts of power directly to the processors. The jacks feature solid pins that can handle more current than hollow-pin connectors.
A VRM with 10+1 DrMOS Power Stages delivers the power and efficiency that the latest Intel processors demand.
Revisions to the motherboard's trace routing provide the latest Intel processors with unrestricted access to memory bandwidth. ASUS OptiMem II technology carefully maps memory signal pathways across different PCB layers to reduce vias and adds shielding zones that significantly reduce crosstalk.
Top layer – ground ring to prevent lateral interference
Motherboards with OptiMem II technology were tested with Synopsys HSPICE simulation software
M.2 slot supports up to 2280 and data-transfer speeds of up to 32 Gbps via x4 PCI Express 3.0 bandwidth. It‘s the perfect choice for an operating system or application drive, providing fast access to data.
The Intel® WiFi 6 AX200 module is compatible with the 802.11ax standard and pushes theoretical peak bandwidth up to an incredible 2.4 Gbps. Perhaps more importantly for power users, it's optimized for more efficient operation on crowded networks with a lot of competing traffic. Pair your motherboard with ASUS WiFi 6 routers to fully experience the networking potential of WiFi 6.
