I've been looking for a way to easily move my 360 between rooms in my house, and decided that the quickest way, depending on the price of such parts, was to buy an extra power supply. I already have the extra A/V cable and a wireless network adapter, so the only missing part is the power supply. I've already looked at some third-party choices, but I'm looking for something official or at the very least certified by Microsoft. Granted, I can just disconnect everything and move it to the other room, but doing so means running wires through intricate nooks and crannies which is time-consuming if not worrisome in case I accidentally knock something off of my entertainment center or make a giant mess of things in my living room.
