It's been a couple years since I've bought a videocard so I've been researching for the past week. I'm shocked and apalled at how power hungry they are now. Remember when video cards were powered by the AGP bus? Then at some point, a few cards started sprouting Molex connectors. Then came the 6 pin connectors on the PCIE cards. Fine, I can see the need to pump more power than the motherboard can supply. But now high end videocards have two power connectors and draw 250W+, and it's been getting worse with each of the recent generations, and apparently that will continue. Meanwhile, CPUs have become more efficient, hard drives are gradually transitioning to solid state, cars are more efficient even while putting out 2x the horsepower than a decade ago, diesel trucks are cleaner than ever. So why are video cards the exception? Why is an 850W powersupply now the norm for running a single videocard? Will it not end until PSUs aren't capable of keeping up? Is there some physical reason that videocards can't become more powerful without requiring more and more power, or is it just a cost tradeoff?
