The BFG ES PSU is supplied in a subtle cardboard box, with no artwork apart from a simple picture of the unit. The box is sturdy and the unit is held between two thick Styrofoam pieces, this package will provide more than ample protection during shipping. The bundle is nothing out of the ordinary; however BFG have added a set of 5 black cable straps as well as a basic bundle of screws, AC cable and a manual.
