help with power chords

alright ive got most of the regular stuff down, all i need is alot more practice which is what ive been doing if you didnt notice the lack of questions ive had.

plus i need a wee bit of help with power chords. name some good sites that will be helpful or explain some good ones to me

i hear they are really simple but i dont have a music teacher yet so im still on my own

thanks
