PSU:
The PSU bracket can secure ATX (with 3 fixing screw holes) and SFX PSU. Some ATX PSU’s air intake will face toward GPU’s air intake. But it won’t affect its performance.
Warning: before using PSU, make sure to unplug the mini PC’s power adapter. If the power adapter and PSU are used at the same time, there is a risk of short circuit, which might damage your device.
CPU And RAM:
Right now the B550 does not fully support 5600X and 5700X CPU. When using these two CPU, we will need to limit the dual RAM speed to 2666MHz or to use single 3200MHz RAM only. If customers need help to adjust the RAM speed, please contact our support team and we will send you a BIOS update file to adjust the RAM speed to 2666MHz. But right now we recommend customers to use CPU ended with “G” like 5700G.
GPU:
Please note that the graphics card dock can only support up to 2 slots cards. 3 slots cards won’t be able to fit in. Also the side of the graphics card need to be thinner than 54mm.

How can I buy a replacement gpu base for the minisforum B550? I bought mine over 2yrs ago and don’t have the original order number any more. My original gpu base was damaged due to a gpu overheat.

Any bios update for the B550? The last version is from 2022.
The external dock for GPU supports PCIe 4.0 or only 3.0 GPUs? What is the recommended GPU support (AMD or NVIDIA)?

Hi Elias, the B550 may have problems when using other CPUs. In some cases, you will have to reduce the memory frequency. According to the customer feedback, not all single memory uses work properly. Therefore, we recommend using 4350G/4600G/4650G/4700G/4750G/5600G/5700G CPU only.
