Guide to add another USB port to PS3

It’s not illegal, but it will void your warranty. PS3 Slim’s motherboard has the capacity for one more USB port but Sony decided to go with two like the 80GB Downgraded phat PS3′s.

j0nnymofo from has assembled an easy to follow tutorial to add another USB port to your PS3. Yes, you do need to solder.

You will need the following:

  • A good solder gun.
  • A knife or blade
  • usb extension lead.
