Best Micro ATX Motherboard for Ryzen 7 3700X

Best Micro ATX Motherboard for Ryzen 7 3700X


Among the most amazing third-generation Ryzen processors is a powerful octa-core processor, the AMD Ryzen 7 3700X. The efficiency of AMD Ryzen 7 3700X is much higher than that of Intel Core i9-9900K, Intel’s bestselling mainstream processor. The processor contains eight cores and 16 threads, making it perfect for all sorts of applications, including gaming apps or intensive ones like Adobe Premiere Pro, After Effects, or even technical tasks.

The AMD Ryzen 7 3700X is a great processor, but it can only achieve its maximum capacity with the best motherboards. The motherboard is the foundation of your computer. It binds various devices and modules so that the PC can operate smoothly and effectively. If you only want a budget board that is compliant with the processor or a beastly overclocking board, we have got you covered with our high-quality top seven picks.

Here are our top six picks, but before that, we would like to draw your attention to the basics we think any user should know about.

What To Look for When Choosing a Motherboard

The motherboard is one of those components without which your system does not work, and you need to worry about buying it. Here are just some of the features you must look for when you are buying a motherboard.


Like every other socket, the CPU port connects the CPU to its power supply, in this case, the motherboard. Each processor has a different form of the socket, and the motherboards are made with that in consideration. Some motherboards are specifically built for a particular processor, and they only operate for that. Various sockets include the Pin Grid Array, the Zero Insertion Power, the Land Grid Array, and the Ball and Grid Array. The Ryzen 7 3700X requires the motherboard to have an AM4 socket.


The BIOS is what activates the hardware and performs the functions of the operating system. It also provides you a user interface to manage a variety of hardware functions. Additionally, it is a conduit between the physical processor and the operating system. It can also offer you other features, such as fan speed control and overclocking. A successful BIOS would keep the machine running at optimum performance and, in the long run, provide you a convenient-to-navigate interface.


Random Access Memory is where all CPU commands are saved while operating. It enables the processor to gain quicker access to items. Eight GB is more than enough for average users, but higher amounts of RAM are necessary for gamers and other heavy users, with 16 GB being quite common. Users engaging in very intensive tasks using up a lot of resources may opt for 32 GB. Most motherboards have more than one slot, with two and four being the norm in most cases.


The PCI-e slot on the motherboard is where you connect your GPU. Like the RAM slots, you could get a motherboard with more than one slot for the GPU. The new version is the PCI-e x16 that transfers 16 bits per loop, bringing you powerful speed. Until purchasing, you can review your GPU configuration for compatibility with the motherboard slots available.
