What cables do you need to make a PS3 HD?

It doesn't need any cables to work. If it's not broken it works.

If you'd like it to run, however, you need a power cord; basically a power cord from a computer is what a ps3 uses.

Now, if you'd like to be able to use it, you need a hdmi cable or component cables.

To use a wireless controller, you'll need a usb in order to recharge it's batteries.
