No, the connection is just a little different. It doesn't look like it is, but when you try to connect it to the unit, it won't.Can I use an old Xbox 360 powerbrick with a newer Falcon chip model xbox?
yes, it will probably be more efficient than the old one too because it has the capacity for more power, but you're only using about 2/3 of that (at least that's how it is with pc power supplies) It will definately work though.Can I use an old Xbox 360 powerbrick with a newer Falcon chip model xbox?
