Topower keeps the packaging simplistic. On the front you get just enough information to let you know if you're interested in the unit with the wattage, SLI and Crossfire logos and the 80Plus Gold logo.
Flipping over to the back, we find a bit more information on the features of the TOP-1000WG. Most notably, we see that there are multiple 12V rails, 6+2pin PCI-E support and a list of incorporated power protections.
The sides of the box do not contain any information, but flipping things over to the top, we find a good list of connectors that are available on all the power supplies in the Nano Series.
On the bottom we see the I/O specifications for all of the Nano Series power supplies.
