Jou Jye's packaging is rather simplistic for the BW-B620JL. Little is listed other than the wattage and a few miscellaneous logos on the front of the box.
The back has some more information with efficiency, noise, fan speed and more features. We also find the first mention of linking the power supplies...you'd think they would make a bigger deal out of this as it is their main selling point.
One side of the box has the I/O specification label.
The other has some connector availability information.
Both the top and bottom of the box lack any useful information.
