I have spent a lot of time on one forum or another and Moderated on one until it shut down earlier this year. I do not remeber seeing any issues with the CX series of PSUs, in fact I've noticed that some top rated Boutique builders have been using them. I believe that CX 500m is full modular. YOu are right in that Modular or non modular has no effect on the caps used and that is an important consideration. My point is that from my experience, I have seen no issues with the CX series.
