In the following question, the user is asking for factual information that might help him to make an informed choice when buying a new PSU:
I do not have sufficient reps to see if there are any close requests, but one user has has suggested that this is a "support request" and therefore off topic.
This seems to be a little perverse to me, since the OP is in a pre-purchase situation and simply wants to know what a technical term means before he makes a decision.
My question, therefore, is: should questions that ask for factual information that will help a user to make an informed decision (and do not solicit opinions) be considered on-topic?
I also wonder how many such questions have been closed as off-topic, and OPs sent away with fleas in their ears, never to return?
