PC Power & Cooling gave their packaging a major upgrade for the Mk III as they have switched to white packaging. They keep it simplistic on the front with minimal information and a ghostly image of the unit.
Flipping to the back, we find a nice list of features and specifications on the unit including the I/O specifications.
The top is identical to the front.
The bottom is the same with a few more pieces of information such as the model and serial numbers.
One side of the box displays a nice list of cables and connectors with lengths.
The other side is lacking any useful information, but does give a nice full color shot of the power supply.
