The TX550M PSU is supplied inside a robust cardboard box with a black-yellow theme, identical to that used for the rest of the series. The artwork on the packaging is simple and but there is a wealth of information about the unit itself around the sides of the box.

Inside the package, the power supply is very well secured between Styrofoam pieces and is enclosed inside a black pouch instead of a standard bubble bag, which pouch you can reuse for any purpose you see fit.

The bundle that is supplied with the TX550M PSU is simple and straightforward. Except from the black pouch which protects the PSU and the standard AC power cable you will also receive several short black cables ties, four black 3M screws and a warranty guide. You will also receive the modular cables but inside a mere nylon bag. There is no storage pouch specifically made for the cables or anything similar inside the package; you can use the large black pouch enclosing the PSU if necessary. Two of the cables are not sleeved but a ‘flat’, entirely black cable. The thicker cables are entirely black but sleeved as well, as well as all of the cables hardwired to the PSU.
