You can talk what you want but 1000 P2 and 1200 P2 are great PSU and not only them.
But these two models are really great. Sometimes some batch have lower number of RMA.
Take a look on Newegg customer experience. 1200 P2 have 45 (5 eggs) and only 3 (0 eggs).
4, 3, 2, 1 not exist. But some people report short cables as negative comments.
If you see something like that confirmed stable and reliable than you should buy them because and good manufacturers
sometimes launch second batch with less quality.
Super Flower make excellent PSU but they become more famous, and most people hear for them after they made deal with EVGA.
And they need to continue to make quality products, because if they fail than customers who had problems with EVGA PSU will avoid all their platforms.
