huh?
The only way this article makes sense is if the USB powered VoIP adapter
uses 420w (And if it does, it will either get turned off, or fry your
motherboard, depending on how cheap a motherboard you purchased)
Whether the power comes from a fairly efficient power supply (the one in
your computer) or the cheapest brick the Chinese could create doesn't
change the amount of energy consumed.
What you need to do is balance the energy lost due to the lack of
efficiency of most bricks, vs the amount of additional time your
computer will be left on to only service the VoIP adapter.
In a commercial setting, PCs will typically be left on 100% of the time
while the employee is close enough to use the VoIP adapter, so there is
no loss at all.
I don't have anyone in my life that turns off their PC other then my
grandmother. Most have PCs configured to go into low power mode when
not in use, so the energy savings is fairly minimal.
