The rumored new speed for the CPU is unbelievable. Really. No one can believe that they almost tripled its speed with no serious consequences.
But a more modest increase could be possible. Heck, Nintendo said that the WiiU was designed to use about 45W when playing yet when it was launched and the media tryed it, they recorded a consumption of "only" 35W.

is it that uncommon for a new console not being pushed to it's limits? also, i think 75W is wii u limit.
abot the cpu/gpu clock increse, i have no idea if it can be done or not but i read it wouldn't cause any consequence if the cooling and rest of the system were designed with that in mind to begin with. if true it would be kind of a surprise to everyone since increasing power was only possible with add ons.

No, that's the rated wattage for the power brick.
Of those 72 or 75W you have to substract what it is lost due to the efficiency of the power brick (most of the new PC Power supplies are about 85% of efficiency or higher), then there is the overhead that must be left for safety reasons (you don't really want it to be always at 100% of its capacity) and other things that also make you lose some W.

Doesn't work like that.
A PSU has a rated maximum it can provide to a system, the deduction of efficieny/wasted energy is made PRIOR to the output so it has no bearing at all on anything we are discussing (but might be a good topic on a Greenpeace type forum).
A power brick rated at 75W can provide a consisten 75W of power to a device. The Wii-U would obviously not be going at those limits 100% but it is perfectly "ok" from a design perspective to be using 75W 100% of the time as that is what it is rated to. That's not the "limit", the "limit" would be higher than 75W but 24/7 use can't be guranteed at a higher draw than that.
Computer PSUs are the same a rated "650W" PSU has to be able to provide 650W continuously to the system (with caviats of certain rails only being allowed certain amount of ratio of that power draw etc, but that's a separate PC thing). The actual power draw is going to be around 750-800W on a fairly decent PSU, that gives 80%+ efficiency rating.
Note as said above, those "80%+" guranteed PSUs aren't outputting 80% of 650W for example :)

To be fair, some cheap power supplies in the late 90s did just as he described, said it was 250W but that was peak, constant was around the 200 mark lol.
