No (Very, very, very, very little) power is being consumed, the relays are simply getting a signal to allow power through.

That doesn't sound legal. The external 12 V is connected to whatever load you've got, and the relay is connected to the joystick port and the 12 V supply (though one feeds the coil and the other is switched).
