That column means that the specific power supply unit is compatible with that model.
http://www.edepot.com/playstation3.html ... wer_SupplySo in this case it is compatible with all those models you mentioned (including your CECHC).
Note that the table does not include EVERY compatible PS3 model. Some will work, some will not.
The main criteria is that the pins are the same, and it will fit in your PS3 (screw hole placements, size of power supply unit, etc). You will have to do more research to find out if some that are not listed in the compatible column will work with your specific PS3 model. Feel free to update this forum on your own research results, which will be incorporated in the PS3 Secrets page. Note that for the APS models the newer, the more power efficient, so it is generally ok to substitute with newer models. Also note that even though for some power supply units, the pins are not the same, you can convert them and they will work on your PS3 (you must know which to connect, and which to drop or split, and that is in itself a whole different area of expertise that I won't get into in this post).
The rated power on the power supply unit is usually the max supported, but as you can see, most games when taxing the PS3's GPU to the max don't even approach the max watts of the power supply, so you can be safe knowing that getting a more power efficient model of the power supply will most likely extend the life of your PS3 (assuming you know what you are doing).
