It's not specifically a powerlifting program, but it includes all the powerlifting moves, and I started with it: http://stronglifts.com/5x5/

If you're a beginner the difference really isn't going to matter.

It's good because, as opposed to Starting Strength, the material is all free online, it's all one web page with instructional videos, and the guy has mobile apps you can use for free.

Seconding SL 5x5. It starts you light to work on form, and ramps you gently but steadily. I'm lifting weights with good form now that I didn't think I was capable of 3 months ago.

I also really recommend Alan Thrall's form videos on Youtube. Incredibly instructive and thorough.

As others have mentioned here, Mark Rippetoe is my authority. He might not be perfect, but he's thorough and I trust him.

Starting Strength is excellent, but if you'd rather wet your feet first with some video, check out the series he did with Brett McKay of Art of Manliness:

first rule: find a good pt who can teach you the correct form for every single exercise. That is the most important thing. People think that powerlifting is about "moving the heaviest weight possible"... it is not. It is about "moving the heaviest weight possible without failing at doing it with the _perfect_ execution form".

Another vote for 5 x 5. The app is a little in-app spammy, but the free features more than make up for it. There are even linked youtube videos for each exercise.
