So I have the Z390-A PRO motherboard, and 500W smart Thermaltake. Everything is plugged in correctly, it’s plugged in. This is my first time building a PC and it’s been a nightmare, this is my second motherboard and nothing is turning on, I know the power supply works because the indicator lights turned on on my prior motherboard
 
Not exactly sure how to answer what CPU I’m using, I’m completely new to this.

Maybe your motherboard does not have CPU Installed?
