I bought brand new Ryzen 5 5600x, msi b550 mag tomahawk and asus tuf gaming 650w psu. When tried to power up pc is not reacting like there is no power, but I checked everything many times, tried BIOS update many times... Converted usb to FAT32, and renamed file to MSI.ROM, while nothing is connected to the motherboard besides psu, and still nothing. So i send cpu to service, and they said it's working fine. Also checked psu on my old motherboard it boots up everything fine. I read on other forums people have same issue with this particular board and cpu, there were no answers.
