You might as well include all 87 brands commonly sold. If you include APEVIA, and Rosewill, all the rest should be listed.
You could easily add Delta, Sparkle, Enhance, FSP Group, Corsair, and OCZ.
Seasonic, FSP, Sparkle, and Delta make a lot of those "Sold By" others.
You can tell who really made the power supply by their UL numbers.
Seasonic makes power supplies for Corsair, OCZ, PC Power and Cooling, and many other brands.
OCZ are made by several different manufacturers, as OCZ is merely a label. Think of them as Sold By. Same with Corsair, Rosewill, and so many others.
Power supplies are made to sell, to market. Not all Antecs are made by Antec. Same with CoolMax, and Cooler Master, and perhaps a great number of others.
Now that PCPower and Cooling is part of the OCZ consortium, they do not make all of their power supplies.
With at least 87 different "sold by" power supplies with the common difference only being the label slapped on them, the fact that manufacturers change while the label remains the same, and the UL numbers difficult to interpret as to whom the real manufacturer is, the entire exercise is a joke.
Why include in a "comparison" with a Seasonic with a Rosewill
