Hello, hoping someone can point me in the right direction here. I have a CX 750F RGB modular PSU that I got for my Ryzen 5 3600 CPU and b550f mobo. When I connect everything to the motherboard, the CPU fan turns on for a second and turns off. I also notice that the PSU fan and its RGB doesn't turn on. I played around and removed the CPU cable just to see what would happen and my RAM sticks worked, CPU spun for a good few seconds and my PSU fan was working together with the PSU RGB.
Is this whole PSU faulty or could it just be the CPU E-ATX cable that need replacement? I did try an older PSU that I have and my computer was able to boot up.
