Question Changed computer cases and now PC will not power up at all

[MinKee]

I have a ROG strix z790-a motherboard, msi 1000g PSU, GeForce 4070 super, I just changed over from a pre built case to a ASUS tuf 502 case, I am re using the fans from the pre built case. All of the components were in the original case working fine, when I plug in the new case the motherboard rgb turns on but when I press the power button nothing happens, anyone have any suggestions on a fix could be? It looks like everything is plugged into the motherboard correctly
