Evga is making me mad with their PSUs. They are pulling a Corsair. Perfect textbook definition. Some good PSUs that review VERY well, then some other junk in the same series with the same name to confuse people into thinking they are also quality units.
Corsair RM series is a great example. 450,550,1000 are all VERY good units. But the 750 and 850 aren't even better than the CX line. WHY? Marketing.
Look at the Supernova NEX650G. Oh its a G unit so it should be amazing right? Nope. Although not bad, it is not great either. Many review sites claim it can't even reach GOLD efficiency, which it claims to have.
Then look at the B series units. Average quality budget units. But then the supernova 750 B2 is really good. About the best cheapest 750w unit you can by which blows away all its direct competitors (cx750).
I'm sick of all this marketing and naming trickery crap.
