I think there's a big difference between "efficiency" and "trustability". You even might be getting a 80+ platinum rated PSU that's garbage. I think that chance is small but still possible. I'm not sure if I understand the rating right, but as far as I know it has to do with how much power a PSU draws compared to how much it needs. The more efficient the PSU is, the smaller the difference. A PSU always draws more energy than needed, and the rating shows how small the difference is.
Here they have an example that shows it on a 500W PSU with a 80% efficiency and 90% efficiency (80+ and 80+ platinum). Point being though is, that even a very efficient PSU can have bad quality items in it and break quickly. Some PSU's will fry your PC if they break, while better quality ones usually have some kind of protection from it.
If you look in the budget segment of PSU's you should always be aware that there has been cut on costs to get the price of the PSU lower and IMO especially with unknown brands you risk that they cut on the important parts of the PSU.
