I'm happy with my seasonic PSUs. 2 of them in use, both very quiet and trouble free. One has modular cables, no problems with the cables at all.
I think there is another company that uses the same PSU with a different brand name on the sticker, but I can't remember which one it is. Hardocp occasionally reviews PSUs and when they do they point out that the brand name on the box is less important than who actually slapped what kind of components on the circuit boards, but they haven't reviewed seasonic in a while so I don't know who makes the seasonic PSUs now.
I just know I'm happy with mine, and if I suspected they were flaky I'd swap them out in an instant no matter how much they cost.
