I know that in the world of electric motors, more weight = more turns of copper = more power. Now, that's motors...I would think though that it reflects some information on overall build quality (more metal, less plastic) and also on heatsink size, which clues you in to how much power the thing is expecting to devour by getting a look at how much heat it will need to dissipate.
