I have a capture card I only use every week or so and obviously it draws from the motherboards PCI power. I'm just wondering that if I disable it in device manager, will this stop the device from drawing power completely as if the device was physically removed?

If this is the case, I imagine the second I enable the device it will act as if I inserted the device and start drawing power from the PCI slot?
 
Thanks. Switched to disable and the thing said D3.

Not really worried but I feel that I can just switch it off when not in use and save some power.
