Mixed feelings, I mean 80+ certification wasn't that important to me, in that I recall many good quality PSU back in the day, that weren't 80+ efficient and it didn't bother me - running say a 250W load and whether the total draw was 295W vs 330W, but I do appreciate that less heat generated in the PSU, tends to increase lifespan, or allow reduced airflow through it for lower noise and dust (if the case isn't filtered).
I had more of an issue with group regulation, when putting together systems with atypical crossloading, like minimial power nas. Even so, I appreciate the argument that all else equal, a better quality semi-modern PSU will have 80+ certification, yet that doesn't tell the whole story and more testing is superior.
I think they shouldn't drop the 80+ cert, because the whole industry isn't, rather have the cybernetics along side it. Even if imperfect, that, along with reviews testing the claim, gives a little more info to evaluate PSU that don't have a cybernetics cert. Plus, we could debate at what skill level someone is competent to build their own *PC*, but many people start to get glossy cow eyes if you give them too much information, can't sort through it or discriminate which of it is more significant. That is not an argument against more info, but I feel that keeping it simple, helps in some cases.
