Absolutely not. And also not from the manufacturer's specs (for those architectures and machines that still have this information published and publicly available.) The reason for this is, of course, that the actual running load of a machine is usually considerably less than these numbers. The x86 Dell PowerEdge line, for instance, uses about twice the power at startup that it does in regular operation, which is in turn still not the full delivery capacity of the hardware; while loading increases this number somewhat, it's a relatively minor increase that's closer to the regular operation number than the startup number. Stickers will only get you the maximum amount the box is *capable* of drawing. Which is fine for some things, but not fine for other things, and not terribly reliable if you're interested in real-world budgeting per the numbers I mentioned above. The way to go is to use a clamp meter, which can be had relatively cheaply. (But you've donated to the project first, yes? Yes. Perfect.) -slr
