I want to make a custom cable for my semi-modular EVGA PSU to provide a single 4-pin connector. I know that pinouts can vary from one brand/model to the next but I plan to make my own cable using a 6-pin Molex Mini-Fit plug at the PSU. I was all set to do that when I ran across a site selling no fewer than 13 different 6-pin connectors! The pictures all look alike but some of the prices are different so maybe they're not all the same. Aside from which pin has +12V and which has ground, will a Seasonic 6-pin modular plug fit and make an electrical connection with a 6-pin jack on an Antec PSU and so on?
