definitive ps3 backwards compatible guide

the purpose of this article is how to identify a backwards compatible playstation 3 (ps3).  i will keep it simple and to the point because there is way too much “bad info” on the internet regarding on this topic.  by writing this article i hope to clear this up with a definitive article, once and for all.

important note:  when i say backwards compatible, this specifically refers to ps3 models that can play ps2 games.  ALL PS3 MODELS ARE CAPABLE OF PLAYING PS1 GAMES!

early models only:  the earliest variation of the ps3 is the only model type that is potentially backwards compatible.  period.  this is the “fat” ps3 with the chrome trim.  they are big, heavy, and have a shiny gloss black top cover with PLAYSTATION 3 in big chrome letters.

specific models:  only three models of the fat ps3 are backwards compatible.  there is a lot of silly info out there as to what to look for to determine if your ps3 is backwards compatible.  most of this info is unnecessary.  it is actually VERY simple.  read on to determine which ones have it and what to easily look for.

identification:  look for a fat ps3 with 4 usb ports.  period.  it is that simple.  if it has 4 usb ports, then it is backwards compatible!

model numbers:  look on the back of the ps3 and the white serial number sticker lists the specific model number of these three backwards compatible models.  20gb ps3 = CECHB01, 60gb ps3 = CECHA01, and 80gb ps3 = CECHE01

additional info:  the 20gb and 60gb models are fully “hardware compatible”.  they basically have ps2 chips inside of them.  it is reported that only a few ps2 games might not be compatible with these models, which makes these models very desirable and in demand.  the 80gb model only has partial ps2 hardware and partially “emulates” the software.  it is reported that there is a confirmed short list of ps2 games that might not be compatible with the 80gb model, which makes it slightly less desirable but still in demand.

80gb model note:  there is a false rumor floating around that this model must have its original firmware or system software to be backwards compatible.  THIS IS NOT TRUE.  i personally JUST updated my 80gb model to the latest software version and it did not effect its backward compatible ability to play ps2 games.

cheat sheet summary:  to positively ID a backwards compatible ps3 either look for a “fat” model with 4 usb ports OR look at the model number:  CECHA01, CECHB01, or CECHE01.
