Please redo your question. It makes no sense. Are you using Google Translate to change your native language to English? I've noticed that Google will sometimes really mess up what you are trying to say. Try posting your question both in your native language AND the Google Translation. Maybe between the two I can figure out what your asking.

If you want to know where to buy a power supply or how much one would cost then you should visit eBay or Amazon. You will find very good examples in both places. You will want to know how many Amps and type of voltage you will need to supply to your project before you decide to buy.

Good luck. Dave Schulpius

Like I mentioned earlier you will want to know how many Amps and type of voltage you will need to supply to your project before you decide to buy.
