A power "chord" is any combination of a note and a perfect fifth (seven consecutive notes up). (It can be disguised as a note and a perfect fourth - five consecutive notes down. Notes repeat like hours do.)

You can double/repeat these notes as desired.

So all of these are valid power chords:
(high string)
e|---------2---------0-------3-----5---5-7-0-|
B|-------3-0-------1-0-----3-3---5-3-5-5-5-5-|
G|-----2-0-------0-0-----2-2-0-4-2-2-4-2-4-4-|
D|---2-0-------0-0-----2-2-0---2-2-0-2-2-2-2-|
A|-2-0-------0-0-------2-0-----2-0---2-0-2-2-|
E|-0---------0---------0-------0-----0---0-0-|
(low string)

(some of them are easier to play, though.)

Btw, there's a power chord thread just a few threads below Next time, check if there's a recent (within the past month or so) thread around that's relevant.

(also, consecutive notes is a less technical way of saying half-step or semi-tone. These and whole steps/tones (two halves make a whole) are the basic interval building blocks of Western music.)

OK, understanding this post, is going to depend on if you've assimilated Neo's tutorial on power chord construction.

Well, a "power chord" is often notated as "G5", or any combination of root letter (the "1st" of the chord), with a trailing "5".

The extended answer is that you can make a "5" chord anywhere on the fret board, but is it actually worth calling a "power chord".

I tend associate the term "power chord" with the lower register chugging of heavy metal, as opposed to "lyrical double stops" happening at the 15th fret.

But yeah, they are both "5" chords, and so the names I suppose, are interchangeable.
