CPU power reference

Base and peak power for each desktop CPU, with a cooling-class guideline and a link to size a power supply. Figures are vendor-published; where a manufacturer does not publish a peak (some older parts), the page says so instead of guessing. Results are for planning — verify against the official spec before you buy.
