Another trend that is obvious to those of us who follow modding, even if just a little, is the increasing demand for so-called 'modular' PSUs. A modular PSU is one that allows you to connect only the cables that you need for your system, thus reducing clutter and hopefully increasing airflow inside your case. This type of unit allows for instant customization and a great amount of flexibility. At first, modular PSUs were only seen at online retailers that offer custom products and modding supplies. Now, there are several modular PSUs being mass produced, and one of those is the NeoPower 480 from Antec.
