PS3 Fat vs Slim: What's Different (Including a Feature You Might Miss)

Updated August 13, 2026

The PS3 went through several hardware revisions after its 2006 launch, broadly grouped into "Fat," "Slim," and "Super Slim" generations. The differences go well beyond size — including backwards compatibility, which changed significantly and unevenly across early models.

The original PS3 ("Fat") — 2006-2008

Launch and early PS3 models are large, heavy consoles that — critically — included varying levels of PlayStation 2 backwards compatibility depending on the exact model and region. The earliest launch units used genuine PS2 hardware components internally for full hardware-level compatibility; later Fat revisions moved to software emulation with more limited compatibility, and the feature was dropped entirely from later Fat units before the Slim redesign arrived. This makes the specific model number, not just "Fat vs Slim," the real deciding factor for PS2 compatibility.

PS3 Slim — 2009

The Slim redesign is significantly smaller, lighter, and quieter than the Fat, with a noticeably reduced power draw. It has no PS2 backwards compatibility at all — by this point Sony had removed the feature entirely from current production. It also switched from an internal power supply layout to a smaller design, contributing to the overall size reduction.

PS3 Super Slim — 2012

The final redesign shrinks the console further and replaces the sliding disc-loading mechanism with a hinged door covering a slot-loading drive. Functionally similar to the Slim otherwise — no PS2 compatibility, similar performance — with the tray mechanism change being the most noticeable practical difference for day-to-day use.

The PS2 compatibility question — check the exact model

If PS2 backwards compatibility matters to you, "Fat vs Slim" isn't specific enough — you need to check the exact model number, since compatibility varies even within the Fat generation. The earliest launch models (with full hardware-based compatibility) command a real premium among collectors specifically because of this, separate from general PS3 collecting value. Always verify compatibility for the exact model number before buying with this feature in mind, rather than assuming any "Fat" PS3 has it.

Frequently Asked Questions

No — PS2 backwards compatibility varied even within Fat PS3 models and was removed entirely before later Fat revisions, let alone the Slim. Check the specific model number, not just "Fat vs Slim," if this matters to you.

No — PS2 backwards compatibility was removed from PS3 production before the Slim redesign launched. Neither the Slim nor Super Slim support it.

The Super Slim is smaller still and replaced the sliding disc tray with a hinged door over a slot-loading drive. Performance and compatibility are otherwise similar to the Slim.

Among collectors who specifically want that feature, yes — launch-era PS3 units with hardware-based PS2 compatibility can command a real premium over later Fat and all Slim/Super Slim models.
