So I have an Xbox 360 that's less than a year old. I don't know what model or revision or anything it is but am just trying to figure out what I need if I pick up a used Kinect. I keep seeing things mentioning the power cord and whether or not I need one or not which is my question. Is it just original Xbox's that need the separate power cord or is there a chance mine would as well? I'm looking on eBay and Craigslist and many say it's the Kinect only so I just want to make sure that's all I need. Any info would be greatly appreciated. Thanks!
