The external packaging informs the buyer of what they are getting very well. The front shows all of the important information to determine whether or not it will suit your needs, including power output, efficiency, support for 6/8 pin PCI-E connectors and more.
The back simply repeats the information listed on the front, but in a multitude of different languages. SilverStone also uses the same box for the ST85F-P and ST75F-P power supplies and their information is located here as well.
On the sides and bottom of the box we can find some expanded information about specific features of the ST1000-P such as the output specifications, connector availability, fan speed, efficiency, and even the optional short cable kit available separately.
