Power Supply

There are two ways to power the PC. If you use AMD APU like 5600G or 5700G, there is a standard 19V power brick included in the package and you can use it directly without using the supporting dock.

By doing so you can use desktop CPU like 5600X in this mini PC and the whole system’s power consumption will be more than 600W. The mini host of B550 has cooling solution which supports 65w TDP.



Optional configuration includes barebone / 16GB (8GB x 2) / 32GB (16GB x 2) memory and 256 / 512GB SSD. You can access the inside by removing the four screws that secure the bottom. There are three types of expansion space inside. You can further increase the capacity according to your own needs.
