That seems to be the case here
Most of the time with components like motherboards in order to get into the bios a CPU has to be installed most will not power on at all while some will power on for literally a split second and it's not even enough to spin the system fans. As Bishop said outside of the Enterprise market very few boards turn on without a CPU installed and B450 is a chipset that doesn't. I think some of the ASUS high end boards do but that's for updating bios before you install the CPU like CUDA said in his post.
