I have a power button on my case that has 4 pins but I don't see a pin connection with the same labels "POWER SW", "-PLED", AND "+PLED". Does this MOBO not support power buttons or do I need to connect them to a certain spot?

Nvm I found it... bottom right corner there is a white set of pins that has the PLED+/- etc
