No imminent-failure issues, thanks
I'm just looking for efficiency in the face of a lot of peripherals that don't need to be on all the time.
In my own limited theory, if I disable something in device manager and hooked-up an ohm-meter there would still be power available at the jacks, but the question on my mind is whether a certain wattage is still being consumed.
The inspiration for this, is I'd rather have my main box on an opposing wall (so exterior cables can be kept short and sweet) but then access inside would be limited.
Computers are spiky with power demands all over the place, so I hate the idea of 1/5th my power being unavailable for system headroom, if that makes any sense.
I'd probably save a lump of coal every now and then too, not that I'm excessively Green though.
