The GSP850-SM comes in a black and gold package. The front clearly displays the wattage, warranty, 80Plus certification and lots more.
Over on the back we see some features of the power supply as well as the available connectors.
One side of the box is a repeat of information, but the other side contains the I/O specifications for all of the GSP PSU's. It looks like they use the same box for all four models. The top and bottom of the box do not contain any useful information.
