Corsair hasn't changed the packaging for the TX550M at all. It is the same yellow and black packaging that we've seen on all the other TX series power supplies we have taken a look at.
More of our usual information here with the list of features, I/O specification, a few charts for efficiency and noise and a little bit more.
The top of the box gives us a little bit of information in multiple languages.
The bottom does the same with only slightly different information.
Both sides are the same and lack any information other than make and model.
