You know it suddenly dawned on me after I posted this that I should do that. Then I felt like an idiot and wished I haden't hit submit.
I am going to play around with it this weekend. I don't think it will make a big difference because the power cord is going into a power supply. The cord on the other end is hard wired to the power supply and plugs into the XBOX 360. The old XBOX allowed you to plug directly into the back and the after market cord made a huge difference.
