The box for the i700 is very plain; it’s a simple cardboard box with black ink used. You can’t get much more basic than this, and considering it’s a budget power supply, it’s not surprising to see this. Besides, who actually sits and looks at the box after you remove the unit anyways (assuming you even keep the box)? Yes, we’d rather have those savings passed onto consumers than used towards a fancy box. We see the name of the unit, some basic information, and the fact that this power supply is 80PLUS Bronze certified, which is good to see for this price range and wattage.

The rear of the box contains a bit more detailed information about the features and specifications.

The accessories included are unsurprisingly extremely minimal: User’s Manual, mounting screws, and power cable. Barebones, but everything you need to get up and running.
