> If some of Nvidia's next generation 4xxx series GPUs are close to 1000w draw as many rumors suggest

Those rumors are for millisecond long transient spikes, not an average of anything. So basically the rumor is a 500w peak load. Just like how the current 350-400w GPUs have transient spikes to upwards of 800w. It's not a problem in terms of power consumption (although obviously the increase from 400w to 500w would be), rather it's an issue with over-current protection in power supplies tripping. It's a "need bigger capacitors" type problem.
