Adding up System Power Watts

[Seraphic]

Was trying to add up my system watt total.
But want to know, do PCI/PCIe cards use power when not active?
I mean if you have a card that records audio for example, does it use power when not active and recording? Does it draw power just being installed into the motherboard and idle?

My guess is that it would draw a small amount of power, but not a lot.

This wattage calculator seems like a pretty decent one, up-to-date too with all the new i7 stuff.
