The Elite 360 console I have sitting next to me is 203w.
Just checked my new 360 and it is 135w.
So the power requirements are almost identical from the current 360 to the XB1.
Don't know if the Alibaba numbers for the PS is accurate or not.
Bluray drive: Less than 25w (18w) [10w with BD2003's input)
RAM modules: 4 watts each (rough guess) 16w total [12w considering XB1 is using 2gb sticks]
Chip: no clue
Kinect: no clue (25w guess) due to camera/microphone and chip??? [not sure what to make this since K2 has a chip on board, I think as mentioned below there is a special USB, so not sure if this is USB on on bus with full power???]
MB: 25-55w guessing. 25w [20w meeting in the middle with mine and BD2003]
Fan: 6w guess (5w guess) [3w - BD2003]
HDD: less than 5w (4w guess) [3w - BD2003]
Rough wattage total: 18w+16w+25w+25w+6w+4w= So rough guess is 94w excluding Chip. Which leaves 21w for chip.
Adjusted wattage total: 10w+12w+?+25w+20w+3w+3w= So new rough guess is 73 excluding chip and making wild guess on K2. Which leaves 42w for chip. This is starting to look a little more plausible expecially if the K2 is only 15ish watts, that gives APU about 50w, which adds up to matching the watts below on those similar chips. Granted the XB1 is customized with a few additions.
Probably forgetting stuff to add and just guessing on wattage based on quick internet search.
Based on these projections for Jaguar chip, maybe this isn't too far out there for power draw.

Thanks Bd2003. I have updated above based on your post below:

BD drive is 5-10W.
Kinect is powered by USB 3 AFAIK, so that's only 5W max.
A 4GB stick of ram can be less than 2 watts, so maybe 5W max for all 8GB?
The HDD is maybe 3W running at full blast, same with the fan.
Motherboard maybe 10-15W.
Plenty of room left for the APU to take the lions share of the power.
