Corsair used to be really solid all across their range, they have slipped lately I feel (or maybe not being in the front). It used to be very easy to recommend a PSU, a Corsair was always a good and solid choice. Now tho with especially the CX series they ride their good name from past. Mind you they still sells really top notch PSUs (AX and HX mainly), but no longer Corsair PSU=all good, why choose anything else?
Forgive me for being bias, but not, I don't mind trying XFX, Superflower and Ultra but when that time comes that I have to make the final decision, it always ends up to the obvious brand.
There's an old saying; if it's not broken, why fix it?
