MSI A520M-A Pro AM4 AMD Micro-ATX Motherboard

PRO series helps users work smarter by delivering an efficient and productive experience. Featuring stable functionality and high-quality assembly, PRO series motherboards provide not only optimized professional workflows but also less troubleshooting and longevity. MSI motherboards let you manage speeds and temperatures for all your system and CPU fans. Total Fan Control allows you to check your primary system characteristics in a simplified graphical interface. You can also set up to 4 temperature targets for CPU and motherboard, which will adjust the fan speeds automatically. MSI PRO Series motherboards support all the latest storage standards, which allows users to connect any ultra-fast storage device. Higher efficiency makes your work easier. An enhanced PCB design with 2oz thickened copper increases conductivity, improving heat dissipation and performance reliability especially during overclocking. MSI OC LAB does not merely work hard on extreme overclocking. Compared to the A320 motherboard memory A-XMP profile, MSI does have great improvement in performance and efficiency for A520 motherboards. Easy to enable A-XMP profile with auto power settings to get the best memory speed and stability. 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 but also creating the perfect conditions for your CPU overclocking.
