Update:
I have removed the list of recommended power supplies for a good reason. Not only that its outdated but also the quality of the newer vx, tx and hx series of corsair power supplies have degraded compared to the older ones. Whether they are still reliable or not is something I can't really say as I've extremely less resources to test/confirm that and its just not possible to get hands on stuff everytime an established model/series gets a new production batch with "minor changes". As far as my trusted source of information through a knowledgible friend goes, vx450's 3v and 5.5v doesn't live upto its usual load and as far as I've seen, TX750's 3.3v, +5v and +12v is overpowered.
All I can say is do your research properly and notice the differences (you can assuming you help others to build systems on "special" occasions) by checking out the overall built quality, the sleeving, the thickness of the wire, the connectors, the power plug (you can never be too careful) and once you're plugged it in a system keep an eye on the rails and make a note of any problem on the fluctuation on idle and load. This is something that a genuine advisor can do it but people who copy-paste other people's advice couldn't. So therefore its best if such people refrain from advising others unless you did a proper research- or else you're simply damaging the community this way. There are websites like jonnyGURU, anandtech and hardware secrets make an effort to do a real and a proper review power supply with proper and proven methodology.
