The way I look at the rating as is, it tells me that the main power stage handles both 12V and the 5/3.3V rails on the same transformer (750W rating). The rating on the 5V/3.3V is the maximum spec based on component rating (e.g. diodes, 5V winding) If the 5V/3.3V is fully loaded, then yes it would only leave 557W for the 12V side. It sounds like an old designs uses the +5V as feedback and only have loose regulation on the +12V rail.
Newer ones (e.g. Corsair) converts to 12V and uses DC/DC converter to 5V/3.3V. The +12V rail is more tightly regulated.
