Jason,
CofC is geared to External Power supplies only in this manner. Energy Star has many different categories, including one for External Power supplies, and so it's relevant, but a little difficult to relate to open frame supplies in general.
Also, most of these standards are geared to consumer level products designed for use in a residence.
What our question is really shooting to address is the issue for more OEM types of commercial or industrial or medical types of products that use open frame internal power supplies. We are curious as to how many engineers put value on having a very efficient and low no-load power draw for an open frame supply.
Thanks,
Kent Smith
