Once again Antec supplies the product in an attractive and clearly labelled box. There's no mistaking what you're getting. You get a pretty picture of the CP-850 on the front and a selection of technical information on the rear.
Upon opening you find that the CP-850 is well packaged. Flanked by plastic foam and wrapped within an additional layer of plastic the PSU should have been safely cocooned during transit.
Also contained within are a basic instruction sheet, 3 pin power cable, screws for securing the PSU in the PC case and a selection of modular cables.
