The NeoHE series, afaik, is built by Seasonic to Antec's price point. The newest units *might* have all the larger caps sourced out of Nippon. All thier lesser units are built by CWT and still use Fuhjyyu caps(craps).
Fuhjyyu can live awhile but they must not be run hot or they have very short lives.
Corsair PSUs are built by Seasonic. They seem to be on the M12 platform w/o the 60mm aux intake fan. The Corsair units have reviewed very well indeed. I haven't seen pics of an open M12 to compare to a Corsair.
I have heard that Antec told Seasonic, if you start building for any others...we will take our business elsewhere...Yep! Antec is a big player and could/would do it. They have $queezed CWT 😀
