The quality of a PSU cannot be and should not be judged by its 80+ Certification! This is not a "to each their own" situation: this is fact vs. fiction. There are LOTS of junker PSUs that are Bronze-rated and there are even some junkers that are Gold-rated. Junkers! Shall I make a list? Warning: it will be a large list of PSUs and I will not include all of them because of time constraints. I hope that warning statement gives you an idea of just how useless the 80+ Certification is when it comes to judging a PSU.
Also, and I must stress this very hard: Corsair's "VS" series is not good for overclocking. Not at all. It's their generic line of PSUs intended for office-type PCs only. They should not be used in gaming systems, so they should definitely not be powering an overclocked system!
That's why I said what I said in post #15.
To learn more, read/study these articles until you are able to teach the subject yourself (this is my sincere advice, not a dictation):
On PSU Efficiency
PSU "50% Load" Myth
After understanding these, you will get a little better understanding as to why the 80+ Certification should never be used when judging a PSU.
Also, I forgot to mention that a PSU should never be judged by its brand name. That's clear with Corsair's VS and CX series PSUs, but they're not the only brand how has both bad and good PSUs. Take a look at all of the other brands and look up each series and you'll find that some are garbage and some are the holy grail (and everything in between).
