That listing is as useless as much is possible for a list to be useless. For example Seasonic - you got X series PSU ? Sorry, they won't list those. XFX ? What ? XFX makes power supplies ? Not according to that list. In short, that list covers only very small part of the PSU market and for that reason it is useless to check this problem. Especially if the only informations it has on 12V2 line is yes or N/A (aka "we don't know").
