Enermax go modular with the new Liberty series, but is it worth it? ?Modular power supplies are starting to become very popular for obvious reasons, but there are a few potential drawbacks. Modular plugs can add electrical resistance to the lead. What this means is that almost all modular power supplies are going to be sacrificing voltage efficiency to incorporate this very convenient feature. Another drawback is corrosion of plug pins which could further hinder the unit?s ability to serve good voltages to components." Pureoverclock
