Over the past few years, graphic card architectures have improved on efficiency and lowered power consumption. While it's true that power consumption is less now, it has gotten worse in context of PSUs. AMD and Nvidia are trying to increase efficiency by using tricks like Powertune and GPU Boost which results in power consumption spikes in very short intervals.
Over past few years:
Prices of CPUs remained more or less the same.
Prices of mobos remained more or less the same.
Prices of RAM sticks remained more or less the same.
Prices of GPUs increased.
Prices of PSUs increased.
A good quality PSU costs just a little less than Core i3 now.
