  • Form Factor

The very first thing that you need to consider is the form factor of the motherboard. It determines the size and the connectivity options available on the port. The most common one is ATX form factor which comes in different sizes based on the number of DIMM slots available for memory. If you are replacing your old motherboard and don’t know the exact size, you an always measure the old one and get the one with the same size for accuracy purposes.

  • Socket and Chipset

Next, you need to understand that all motherboards aren’t compatible with all processors. The motherboard and the processor come with specific sockets and chipsets which work like the lock and key model and only the products with the same processor socket and the chipset are compatible with one another. In case of Ryzen 9 3900x, you need the AM4 processor socket and the X570 chipset for to enjoy 100% compatibility.

  • Memory

It is best to choose the type and the amount of RAM that you wish to add to your system beforehand. Make sure to check whether your processor supports the RAM and whether there are enough DIMM slots on the motherboard to support the type and the capacity of RAM that you wish to include. Each motherboard is different, so it is best to get the memory sorted out beforehand.

  • PCI Slots

The PCI slots are connectivity ports added to the motherboard which allow you to connect various peripheral devices to your system such as the graphics cards, video cards, audio cards and more. The more PCI slots you have the more connectivity option you will have. So make sure to opt for the motherboard that offers the number that you require.

  • Built-in Features

In today’s time motherboards come with built-in features such as Wi-Fi, Bluetooth and audio systems. They might be a little more expensive as compared to regular motherboards but do limit the need for peripheral devices at the same time.

  • BIOS

The BIOS is the pre-built software on the motherboard that is responsible for detecting the components connected to the motherboard and also forming a connection between various components. Motherboards come with BIOS which need to be upgraded from time to time. Make sure that your BIOS is compatible with your processor otherwise the motherboard won’t be able to recognize it.

  • SATA

Storage space is one of the most important features of a system. In order to ensure that you have sufficient storage space, you need to ensure that you have the right SSD or HDD storage and your motherboard comes with ultra-fast USB 3.0 SATA ports for connectivity purposes.
