If you are looking for a B550 motherboard, for an AMD processor, I have listed the best motherboards on the market for you by doing my own research on the net.
These are the motherboards I will choose to build a new AMD PC in 2020, although the B450 is cheaper and compatible with the latest AMD processors, in terms of upgradeability the B550 is a vastly superior choice.

I have listed the 5 best B550 motherboards on the market by grouping the 3 best ATX boards, the best micro ATX board and the best B550 mini-ITX motherboard. In this way those who wish to make PCs in small boxes will also be served.

In the rest of the article I will detail why I chose these motherboards so you can choose which one will best meet your expectations.

MSI MAG B550 Tomahawk: the B550 motherboard with the best quality/price ratio

Available for less than 190 , the MSI MAG B550 Tomahawk motherboard is undoubtedly the best value for money among models equipped with the B550 chipset. A habit for the MSI brand which often offers very competitive prices.

One of its assets is to have 2 LAN sockets on its rear panel: a 1Gbps socket and a 2.5Gbps socket. If you want to connect several PCs in a local network, this motherboard is therefore an ideal choice.

On the other hand, it does not have a Wifi card or Bluetooth. Nevertheless, it is always possible later to add a Wifi-Bluettoh dongle.

This is a motherboard more geared towards gaming and compatible with the latest AMD processors. It offers good potential for upgrading .


ASUS ROG STRIX B550-F Gaming (Wi-Fi): the best B550 motherboard under €300

Available at around 240 , the ASUS ROG STRIX B550-F Gaming motherboard (Wi-Fi) is the model that appealed to us the most among all the B550 motherboards under €300.

Note that this is indeed the model with Wifi , since there is also the model without Wifi, but which costs only around fifteen euros less. With this small difference, you might as well turn to the Wifi version. This is in addition to Wifi 6 and it is accompanied by Bluetooth 5.1 .

What is the motherboard for?

The motherboard takes the form of a plate on which the printed circuit, the chipset and the connection ports are soldered. As a result, the motherboard is in a way the control tower of the PC which will direct the various connections to the components and peripherals.

Before choosing a component for your PC, you must ensure that it is compatible with the motherboard. As such, the more you go upmarket, the more you access motherboards compatible with the latest generations of components and the latest technologies. A top-of-the-range model will be more suitable for upgrading the PC, that is to say improving it by gradually replacing the main components in order to benefit from a PC with a longer lifespan without having to totally replace it each time.

Between a motherboard for less than 60€ and a motherboard for more than 700€, the difference is therefore played on the compatibility with the most powerful components, the number of connections, and the possibilities of upgrade.

To choose a motherboard, you must above all take into account the usefulness that your PC will have . If it is a PC devoted exclusively to office automation, an entry-level motherboard is sufficient. On the other hand, if you want a PC to play video games and to access demanding applications such as video editing or 3D rendering, a more efficient motherboard is essential.

B550 motherboards

The motherboard relies heavily on its chipset. It consists of chips whose mission is to operate the various elements of the motherboard: RAM, memory buses, PCI buses, SATA ports, etc.

In other words, the chipset defines the compatibility of the memory card with the various components and technologies on the market. More simply, it defines the range of the motherboard, even if for the same chipset there are several models of more or less efficient motherboards.

Here we are interested in the AMD B550 chipset. This high-end model is designed by the AMD brand, one of the two main chipset manufacturers with Intel. It is suitable for regular use of recent video games and more generally for the use of resource-intensive applications.

Here are the main features of the AMD 550 chipset:

  • Up to 6 native USB 3.1 ports
  • Up to 6 native USB 2 ports
  • Up to 8 SATA ports
  • Up to 2 native USB 3.2 Gen 2 ports (10Gbps)
  • 20 PCIe 4.0 lanes with 3rd Gen AMD processor
  • Up to 4 PCIe 3.0 lanes
  • 8 PCIe 2.0 lanes
  • Support overlocking

Motherboards using this chipset often offer good upgrade potential. The price range of these B550 motherboards oscillates between 180€ and 350€.
