Packaging and Bundle




The packaging of the NRP 1500W unit is very large and simple, but it is also very sturdy. It is a 'box in a box' package, meaning that there are 3 layers of thick cardboard protecting the PSU instead of merely one. The unit is secured very well inside the package which is held between two thick soft Styrofoam pieces. There is nothing at the front or at the sides of the package; only at the back you may find some of its features, and even then the detailed specifications of the unit are nowhere to be found.



Inside the package you will find a couple of pouches for storing the cables you aren't going to use, a detailed manual, typical 3M screws, a couple of cable ties and a warranty card. Strangely, there were two AC power cables in the package. There is also a bag with all of the modular cables inside. All of the cables share the same red-black sleeving and have coloured connectors depending on their type.
