It is logical for that layman to take that advice (assuming the person saying "this is what you need" is considered knowledgeable) - its why we have reviews. That was my point.
If one is assuming someone isn't qualified to make an assessment on something like PSUs, there's a difference between telling them that a brand is okay and a particular model is okay (when acting to help them). The former is not necessarily helpful. That being said, this is a tech enthusiast website, and many folks (such as Elliot here) are knowledgeable and we do them a disservice if we treat them as if they are incapable of using a simple methodology to help determine the quality of a PSU. It hearkens back to proverb about teaching a man to fish instead of giving him a fish
