The same black and gold packaging is used for the X-series 1050W unit.
Seasonic throws a good list of features at you on the back of the box, but also provides a lot of information as well. It is also nice to see a shot of the inside of the unit.
One side shows the front of the power supply and all of the modular connections.
The other gives the specifications of the unit.
The top is rather blank with just a few logos and the wattage of the unit.
Checking out the bottom you will find a list of features in multiple languages.
