Corsair PSUs are made by a number of oems. You can see who made yours here:

Edit:
If you feel the need to avoid all corsair PSUs then add to that list CWT, HEC, SEASONIC, GREAT WALL, CHICONY, FLEXTRONICS since these are the Corsair OEMs. Corsair is just the label on the tin.
you don't get it, the core components are made by seasonic et al. but the switches and design are made by corsair.
