FSP aurum, label removed 550W/650W/750W?

Trying to find the wattage of this Aurum gold, label has been removed and manual isn't specific to any one wattage. What's the easiest way to identify this thing?

I tried to use my psychic abilities to identify the unit, but was unsuccessful.

Why are all the labels and stickers removed from the unit? Without the sticker that has the serial # removed, there is no warranty.
