Its BIOS is simply magnificent. Several users will love how they have provided them with a hockey to turn on and off the LEDs. We liked this because it was quite simple. Our tester also found the fan monitoring easy to operate.

When you do not have the CPU fan or use something else, the board shows an error. You have to change the settings or use another cooling fan for the board. This aspect can be debatable. We found the Sonic Studio III software exciting.

It comes with the Aura Sync RGB software for adjusting the color of the built-in RGB lights. We liked this feature as you can take data from several network connections simultaneously. Few users have bluntly said that the B450 is a straight rip-off of the B350.

We did not feel that way. Yes, many users still find the B350 board useful and even use it. However, the model remains quite suitable for several enhancements. The new version comes with several updated specifications and an incredibly fantastic layout too.

There is also the M.2 Key-M 22110 slot if you want to use it. When you do not intend to use the storage, then you can choose this board. The B550-F, on the other hand, comes with sublime features. Even small things have been taken care of that are a feast to the eyes.
