Yea the Oculus Rift requires a PC. I don't believe an Xbox would work UNLESS it met the required specs since basically an xbox is a PC, BUT I wouldn't chance it.

Does this work on its own or do I have to plug it into something?
Oculus Rift needs a computer to run, and the minimum system requirements for that PC are significant. Those requirements include a video card equivalent to the Nvidia Geforce 970 and 8GB of RAM, which immediately renders most laptops and desktops under $1,000 unable to power this experience.
There are some computers that can be easily upgraded to support Oculus Rift, but in many cases a new PC or laptop will less expensive than the time and money needed to upgrade.
