This device works alongside your existing case power button, it does not replace it. Your existing power button will still work. The device plugs into the motherboards power button header. Your cases power button plugs into the device instead of the motherboard.

It's powered off of a standard USB2 motherboard pin header. On most motherboards this header will still be powered when the PC is off. The device still needs power when the PC is off so it can listen for button presses from a remote, to turn the PC on.
