I cannot do it captain! I don't have the not enough power!
We have been discussing the ultra-low power state of Haswell processors for a little over a week and how it could be detrimental to certain power supplies. Power supply manufacturers never quite expected that you could have as little as a 0.05 Amp (0.6W) draw on the 12V rail without being off. Since then, companies such as Enermax started to list power supplies which have been tested and are compliant with the new power requirements.

Above is Corsair's slightly incomplete chart as of the time it was copied from their website, 3:30pm on May 10th, 2013; so far it is coming up all good. Their blog should be updated as new products get validated for the new C6 and C7 CPU sleep states.
The best part of this story is just how odd it is given the race to arc-welding (it's not a podcast so you can't Bingo! hahaha!) supplies we have been experiencing over the last several years. Simply put, some companies never thought that component manufacturers such as Intel would race to the bottom of power draws.
