I think it's crazy and getting out of hand. I'm seeing more and more threads where people are saying to get a 650W or 750W PSU for a system with just a GTX760 or 7950. These cards are ~200W tops, and even with a system will use just over 300W as a whole. I sort of get it as people usually reply that if you want the PSU to be most efficient then you want it running at 50% of its possible load. But as I try to point out this means when you aren't gaming your PSU is now using <20% of its load, and isn't even in the range where 80+ tests. In the review I read, they can be under 80% at this range. I'd rather load up my PSU and load a percent or three, then let it drop down to sub 20% and lose more.
