I came across the question Will my PSU 450w be able to handle?, but I have seen this in many other cases as well. The basic form is that someone comes along, lists their system specs, and asks about whether a specific piece of hardware will work in their system; in this particular case, whether a power supply of a given rating will be sufficient to power their system with a different graphics card installed.
These questions commonly attract at least a few close votes as seeking "hardware shopping recommendations".
Frankly, I fail to see how those are considered hardware shopping recommendation questions. Yes, they mention hardware components. But no, they don't appear to seek recommendations; the question is fairly authoritatively answerable in that either the given combination of hardware will work, or it will not. Additionally, assuming that the pieces of hardware are named by make and model, sufficient information is usually available online in order to deduce an authoritative answer; the OP might simply not know what specific pieces of information to put together to form an answer.
Am I missing something obvious in how the "hardware shopping recommendation" close reason is meant to be applied?
