Instructions
Determine whether your console has a shiny or matte finish. PS3 Slim consoles have a matte finish that sets them apart from their shinier predecessors.
Look at the logo. The letters "PS3" are etched on the top, which is different from the previous version, which had the name PlayStation 3 spelled out in white writing.
Observe the button structure of your console. Slim consoles have push buttons, as opposed to the touch-sensitive buttons on original PS3s.
Look for a card reader. Original PS3 consoles feature a hinged flap that houses ports for memory cards. The PS3 Slim generation lacks this feature.
Weigh your console. A PlayStation 3 Slim weighs 7.7 pounds.
