I think all too often, people are really overestimating how much power a particular configuration is using. There are scattered posts in the forums recommending that people need at least 600w just to overclock or run a decent video card. Now sure, its nice to have some headroom, however its also nice to save money on a power supply and make other changes like going from 2GB to 4GB or RAM too. Here is a screen shot of how much power my Q6600 system AND a 19 inch LCD are pulling out of the outlets when running the overclocked CPU and video card at 100%:
OK now figure my LCD is pulling in about 20 watts, so the tower is using 300w. That 300w is before power supply efficiency is factored in. Now lets just say my Corsair power supply is running 80 to 85% efficient with that load, that means the components are only using 240 to 255w of power.
Maybe its just people having bad experiences with shitty power supplies in the past, so they overshoot everything now. I've seen people with almost the exact same configuration as mine get pretty much convinced that they needed something close to a Corsair 750TX to overclock.
