I'm going to reword it for you this time
anything lower than 80PLUS Bronze is usually not really worth it, since everything below bronze is made much cheaper.
I'd recommend something like this, and while it's still on sale. Hell, it's even the same steal of a price here in Canada.
Also, efficiency does NOT mean how much of it's power it can give out at any given time, and anyone who told you that is a filthy goddamned liar. Efficiency is the percent of the power drawn from the wall that can be put to the computer. PSUs are required to be rated by what they give to the computer, NOT what they draw from the wall.
BUT, there is a completely different reason why a cheap 480 can't put out 480. It is because cheaper power supplies are rated by max peak, and proper power supplies are rated by max consistent, normally. And cheap PSUs are often also rated at their optimum temperature, massively inflating scores, while less cheap ones are safely rated at normal operating temperature.
EDIT: But yeah, hardly any good PSUs exist below $50 ($45 in the US), other than the rare good 80PLUS white and the occasional low-power green PSU (like the Antec Earthwatts 380D, which, unfortunately, is still not below $50 in most regions)
