switching-PSUs: why can't you usually exceed the 50% of declared power?

Perhaps some people buy high efficiency PSUs for reasons other than saving a lot of money on their electric bill.

The thing is in the end you don't save anything by buying trash power supply. If you don't save, what's the reason to buy trash?

Is it the new general computing section?

I especially like the ones who crank their GPU's to max while sitting on their butts playing video games for 14 hours a day, blowing away gazillions of kWH in energy costs and waste all year, and then claim to care about a higher efficiency power supply to save $2 a year in energy costs. Or the ones who leave the 4,000 watt central air conditioner on an extra hour or two, thereby erasing much of their yearly cost savings.
