Not sure if that's actually a quote but I just made it up. haha. It's also a joke so nobody get their panties in a bunch.
Here is something from Guru. This was done by calculating the difference between the rig idling and when GPU was at full load. Also I believe this was measured at the wall (not 100% sure) so efficiency still needs to be taken into account. So that 173 watts is actually a bit less. Say we have an 85% efficiency power supply the 680 is actually pulling about 147.05 watts from the power supply.
Those are hit or miss based on your personal taste. i like the way they look but others hate them for some reason. On a side note any opinion on the newer bitspower blocks?
VW_TDI_02 is right that they measured the power draw at the wall outlet. During this power draw measurement, their test system pulled 307W from the wall outlet (however, it would be better to say that their PSU pulled 307W from the wall outlet due to what the system was pulling from the PSU). The CPU was idling, but still, their entire system pulled about 261W from the PSU with just one GTX 680 under full load in their test system.
When they had two GTX 680s in their test system, it pulled 473W from the wall outlet. The CPU was idling, but still, their entire system pulled about 402W from the PSU with two GTX 680s under full load in their test system. Link
Even adding 250W to these power draws results in about 475W and and 615W respectively (that is, adding 250W to the "at the wall" measurements and then factoring in 85% PSU efficiency).
How many systems are going to pull 250W in addition to what the video cards are pulling? How many systems are going to be maxing out the video cards and the CPU simultaneously? How often do you max out your video card(s) and CPU simultaneously?
I hope it's clear now that there's absolutely no reason in the world to get a PSU that is "bigger" than 650-750W, even for future upgrades. Seriously.
