AMD A520 Chipset
Get support for Gen 3 Ryzen processors utilizing the AM4 socket, thanks to the AMD A520 chipset.
Fan Control via BIOS and Software
MSI motherboards let you manage speeds and temperatures for all your system and CPU fans. Total Fan Control allows you check your primary system characteristics in a simplified graphical interface. You can also set up to four temperature targets for CPU and motherboard, which will adjust the fan speeds automatically.
Automatic Detection of DC or PWM Mode
Fan headers automatically detect fans running in DC or PWM mode for optimal tuning of fan speeds and silence. Hysteresis support allows your fans spin up smoothly, ensuring quiet operation.
EZ Debug LED
Onboard LEDs for key components will indicate the source of the problem so you know exactly where to look to get up and running again.
Double ESD Protection
Double ESD protection improves the grounding layer around the mounting holes, preventing static discharge surges from damaging the motherboard.
2oz Copper PCB
An enhanced PCB design with 2oz thickened copper increases conductivity, improving heat dissipation and performance reliability during overclocking.
A-XMP
Enable the A-XMP profile with auto power settings for optimized memory speed and stability.
Core Boost
Core Boost technology allows for precise and undistorted current delivery to the CPU. In addition to multi-core CPU support, Core Boost also complements CPU overclocking.
Isolated Audio Design
Like a dedicated sound card, audio components and circuits are located on a reserved motherboard section and electrically isolated.
Separate Audio Layers
Using separated layers in the PCB, this motherboard ensures accurate sound quality for both left and right audio channels.
Click BIOS 5
Fine-tune the motherboard for gaming performance, efficiency, or overclocking. Conveniently flash or upgrade the BIOS in a few minutes from the CMOS Setup Utility. Or, get immediate access to your critical hardware information such as temperature, memory capacity, clock speed, and voltage to view performance in real time.
Enter the Dragon Center
Dragon Center unifies a suite of MSI software utilities into a single centralized application. Take control of advanced motherboard features such as color calibration, live updates, user scenarios, hardware monitoring, overclock settings, MSI Total Fan Control, data-transfer device optimization, and product registration.

VRM Caught Fire

The First Board Died In A Few Hours When The VRM Burned Up. B&H Sent Me Another One Without Any Trouble And That One Seems To Be Working Fine So Far. Seems Like A Fine Budget Board, I Probably Just Got Unlucky.

I bought two

I gave B&H a gift....I lost a power supply but THOUGHT it was the motherboard, the way it was acting. As I had a Ryzen 3 and a 5, I wanted some backstopping for the equipment over time. I hate it when I lose a good computer and can't get stuff to go with my extinct DDR4 or processor or socket. So I bought two, needed NONE, haha. Not as fast as the board I had, but I got that security for a fast system without trying to be too cutting edge. I can lose a motherboard, give a make up a spare to sell or give, whatever I want
