I first learnt my power chords from http://guitar.about.com/library/weekly/aa092600c.htm
Basically, it only consists of the root, the 5th and the octave notes.
For example, given a scale (doesn't matter which one), say DO RE MI FA SO LA TI DO. The low DO, SO and the high DO will form a power chord if DO is the root note.
