No you maximum draw has nothing to do with the size of the powersupply rating.
Agreed, it could be more, but the rated value is what the device is designed for.
Especially since it is been shown that using power supplies rated higher than your needs tend to last longer. Most Current Desktop systems will be running 150-200W yet will come with 300 to 500Watt power supplies.
Very good point, but it does not related to the previous comment. A higher rated power supply tends to handle the heat better or produce less heat, thus tends to last longer because the system is not taxed as much. A good rule of thumb is still to work with the maximum rated values rather than a measured value (just to be a bit more clear). Ideally a safety factor of 75% of the circuit rating if you want to be more conservative.
