We'll email you if the price of this item drops in the next 90 days.

Overview

PRO A520M-S is engineered with PCIe 3.0 M.2, USB 5Gbps, and HDMI™ 1.4, ready for the AMD Ryzen™ 5000 series processors.

The PRO Series is tailored to professionals from all walks of life. The lineup features impressive performance and high quality, while aiming to provide users incredible experience. Users who care about productivity and efficiency can definitely count on the MSI PRO Series to assist you with multitasking and increasing efficiency.

MSI motherboards circuitry ensure the case standoff keep out zones are pure and clean. Moreover, the protective paint is printed around each screw hole to prevent parts from being scratched or damaged to the motherboard.

Onboard LEDs will indicate the source of the problem so you know exactly where to look to get up and running again.

A host of features inject artificial intelligence into key aspects of your computing experience to make smarter, real-time optimizations. The MSI Center offers a clean, minimal interface to customize and manage your PC settings. The AI Engine, for example, automatically adjusts settings based on the applications you're using, ensuring seamless performance.

Core Boost technology combines MSI's premium layout and optimized power design which allows for faster and undistorted current delivery to the CPU at pin-point precision. Not only supporting multi-core CPU, also creating the perfect conditions for your CPU overclocking.

These rich features also help the motherboard deliver stable and powerful performance.

Exclusive MSI Memory Boost technology utilizes an optimized and isolated DDR4 circuit design to ensure pure and undisturbed signals, significantly enhancing performance and efficiency.

Transient Voltage Suppressors (TVS) are safety devices used to protect against excessive voltage. All motherboard models of MSI are equipped with TVS. When the voltage abnormally rises, the TVS switches from a high-resistance state to a low-resistance state, diverting the excessive voltage to ground. This helps prevent circuit damage caused by high voltage.

The 8-pin, 8-pin, and 24-pin power connectors of MSI motherboards are all designed with solid pins. The solid pin design allows for a more stable transmission of 12V power to the CPU, even when handling high current loads.

Corrosive resistance IO Shield to help improve static electricity and reduce electromagnetic radiation noise from the system as well as more durable compare to traditional IO Shields.

MSI motherboards prioritize safety with the embedded Overcurrent Protection (OCP), ensuring crucial components such as the USB ports, DDR memory, PWM IC, and CPU are shielded from excessive current. This proactive defense mechanism curtails the risk of damage or malfunction due to power surges, promoting long-term system stability. This commitment to safeguarding your hardware underscores MSI's dedication to producing motherboards that prioritize durability and stability.

The grounding structure of power phases is the MSI's exclusive design. This patented design enables to suppress the electromagnetic interference (EMI) generated by the power phases and helps to efficiently conduct heat to the copper plane with grounding properties.

Chipset Heatsink
The heatsink is designed to reduce dust and noise and capable of maintaining high efficiency of heat dissipation.

Connect and synchronize with MSI coolers and cases with strategically positioned pin-header locations, including a CPU fan header and a SYSTEM fan header.

Cooling Wizard serves as a comprehensive solution for managing fan settings across all MSI products. It ensures superior cooling performance and noise reduction for your gaming PC, offering compatibility with PWM/DC fans and pumps, customizable options, and intuitive temperature monitoring for optimal operation with one click.

Frozr AI Cooling targets CPU and GPU temperatures. The AI system detects CPU and GPU temperatures and automatically adjusts the fan duty of system fans to ensure optimal performance.

MSI fan headers automatically detect fans running in DC or PWM mode for optimal tuning of fan speeds and silence. Hysteresis also makes your fans spin up fluently to make sure your system stays silent, no matter what.

MSI AI LAN Manager automatically classifies and prioritizes the latency-sensitive applications for online games, giving you the best online gaming experience with low latency.

MSI PRO series motherboards support reliable high-speed storage standards, allowing users to connect fast storage devices. Boost your daily workflow, load large files faster, and enjoy a seamless multitasking experience.
