Way to make computer power on when supplied power?

Hey r/technology, quick question here,I bought an Alexa controlled smart plug, and was going to connect my desktop computer to it, and want the computer to turn on when I tell Alexa to turn the smart plug on, and somehow the computer should automatically turn on, any advice?This is the smart plug btw: http://ift.tt/2u2pWlp via /r/technology http://ift.tt/2uHinOQ
