It was
shipped in a cardboard box along with foam packaging snow to
prevent damage and prevent it from moving around.
The Power Supply Unit (PSU) box is a little different than
the standard PSU. This one is more of a cube shape and has a
handle.
Also note, the PSU itself has bubble wrap to further prevent
damage.
It's very important that a product is packaged correctly
because they can and often do
sustain damage when not.
Included
with this product is a Power Cable and the Power Supply.
