* You point a to 235W power supply as an example of the bare minimum PC power supply-- not too far from my 300W round number.
* You point out that a power supply rated for X isn't drawing X continuously-- a true statement, but it's responding to an argument nobody made. You have to pick a power supply which is rated for your max load-- everyone knows that, or should. It still doesn't change the fact that both max load and average load for X86 are orders of magnitude greater than for most ARM devices.
