Consumers already have the choice of not buying the most powerful card.

Increasing die size to run cores in a more power efficient regime is not going to work, because a) the chips are already as big as can be made, and b) competition will still push companies to run the 250 cores uber fast and figure out some way to push enough power to it.

As long as there is customer demand for this, these things will get built. Given the amount of bad press these melted connectors create, possibly with better engineered power delivery systems.
