No, a motherboard cannot power on without a CPU. It requires the processor to initialize and manage system operations.

I have a strix b550-f wifi and an evga 750 b5 psu. I wanted to know the same thing, becouse new build, and this is what happened. I have my ram installed 24 pin atx connected, m.2 SSD connected, ll120 fans connected with the lighting node core plugged in, front panel audio, USB 3.0, power LEDs power and reset switch. The only thing that turned on was the rgb Asus logo on the motherboard and all of my USB sockets seemed to have power as I could charge my phone on all of them front and back, now that I think about it my board does have an option to update bios wo CPU with USB in the back. Which makes sense as to why only the USB sockets have power . My psu fan dint even turn on like it does with the power on self tester evga gives you. I tried every combination and nothing. Maybe the CPU completes some circuits or something idk. Also wanted to see my ram rgb and ll120 fans turn on, but I will have to wait for CPU and GPU.
Sure, I've encountered the same issue before. The fix involved adjusting the code logic and testing thoroughly.
