What's the difference between bronze to platinum ratings on PSUs? A clear explanation of that is missing from the article IMHO.

[LeetyMcLeet]

The ratings refer to the "efficiency" of the PSU (i.e. how much of the electricity is used to provide your components with power, rather than being "wasted" as heat). You'd have to Google it, but basically each unit offers x % power efficiency at x % usage. So the better the efficiency, the higher the rating (starting from bronze to silver, gold and platinum). No idea what the 'numbers are' tho.

They may have figured it out in the intervening four years.

Couldn't have put it better myself!
