Which PlayStation 3 model was commonly nicknamed the “fat” model?

The original PlayStation 3 model was commonly nicknamed the “fat” model.

The nickname refers to the larger launch-era PlayStation 3 chassis, which was substantially deeper and heavier than the later redesigns. Sony released the first PlayStation 3 in November 2006 in Japan and North America, followed by Europe in March 2007.

Sony later introduced the PlayStation 3 Slim in 2009, reducing the console's size, weight, and power consumption. The PlayStation 3 Super Slim followed in 2012 with another redesigned body and a sliding disc cover. These official product names make the original system's informal “fat” label useful for distinguishing it from later versions.

The nickname is not an official Sony model name and does not describe a separate generation of hardware. It is a community term for the original chassis family, which included several storage capacities and regional configurations.
