I am building a budget 400 dollar pc for the first time. I put everything in the case and plugged all the wires in, with a few complications. I turned on the power supply to see if everything was working but none the fans (gpu, cpu cooler, or power supply) were moving. I found out that my power supply was working with the fan moving with some trick i found online, but when i plug it into the motherboard and everything, the power supply fan does not turn on, nor does any other fan.
