3.5 sata power source question?

[zenyou]

I'm looking for a sata hard drive ac adapter I guess is the best way to put it. Something I can plug into the wall socket that will power a sata hard drive.

Does this exist? I'd like something that is not ps3 specific because it would probably be cheaper, if not it doesn't matter. I just want to have my 'internal' hard drive outside of my ps3 and powered by something other than the ps3.
