Overview
This list might be incomplete. Not every model number or every motherboard for any chassis type might be listed. For fat models (except the early japanese-only SCPH-1X000 consoles), the chassis type names are well known, mostly from the service manuals.
For slim models, it's mostly guesswork based on a small chassis type indicator in the bottom right corner of the label. However, the only publicly known slim PS2-service manual (for a SCPH-70000 console built around the GH-035 motherboard) mentions another name for the K-chassis: LCG-chassis. Both, "K-chassis" and "LCG-chassis" are used as descriptors throughout this service manual for the same chassis.
Chassis types
Fat chassis types
A-chassis
- Models: SCPH-10000, SCPH-150000
- Motherboards: GH-001, GH-003
- Japanese-only chassis used for launch consoles
- Uses the KHS-400A or KHS-400B (in some SCPH-150000 consoles) laser
- Has a PCMCIA-slot and lacks the expansion bay
A+ -chassis
- Models: SCPH-18000
- Motherboards: GH-003
- Uses the KHS-400A or KHS-400B laser
- Has a PCMCIA-slot and lacks the expansion bay
- Has DVD driver preinstalled in BIOS, as do all later chassis
AB-chassis
- Models: SCPH-18000
- Motherboards: GH-008
- Uses the KHS-400B laser
- Basically B-chassis components using A(+)-chassis form factors
- Last chassis to include the PCMCIA-slot and to lack the expansion bay
B-chassis
- Models: SCPH-30001
- Motherboards: GH-004
- North-america-only chassis used for launch consoles
- Very different internal form factor, "splitting" the main board components into two parts, with the smaller board including voltage regulators, RTC, EEPROM and SysCon
- Disc drive has a tilt motor that is only found in B and B' chassis
- Almost identical to B'-chassis and manufactured at the same time, but uses newer GS (CXD2944GB)
- Drive uses KHS-400B laser, as do all drives until D'-chassis (included)
B'-chassis
- Models: SCPH-30001
- Motherboards: GH-005
- North-america-only chassis used for launch consoles
- Very different internal form factor, "splitting" the main board components into two parts, with the smaller board including voltage regulators, RTC, EEPROM and SysCon
- Disc drive has a tilt motor that is only found in B and B' chassis
- Almost identical to B-chassis and manufactured at the same time, but uses old GS (CXD2934GB)
- Drive uses KHS-400B laser, as do all drives until D'-chassis (included)
C-chassis
- Models: SCPH-30001 - SCPH-30004
- Motherboards: GH-006
- Used for european launch consoles and for some later north-american consoles
- Almost identical to C'-chassis and manufactured at the same time, but uses newer GS (CXD2944GB)
C'-chassis
- Models: SCPH-30002 - SCPH-30004
- Motherboards: GH-007
- Used for european launch consoles
- Almost identical to C-chassis and manufactured at the same time, but uses old GS (CXD2934GB)
D-chassis
- Models: SCPH-3000X, SCPH-3500X (GT3 bundle)
- Motherboards: GH-010, GH-013
- First chassis to move all drive electronics to mainboard
- Also moves components from the smaller boards found in B/B' and C/C' to the mainboard, making the console have one single large board (besides the power supply)
- Almost identical to D'-chassis and manufactured at the same time, but uses newer GS (CXD2944GB)
- Battery on separate battery holder board
- Beginning with this chassis, consoles produced for the japanese market use the same chassis as others, and thus include the expansion bay and lack the PCMCIA-slot
D'-chassis
- Models: SCPH-3000X, SCPH-3500X (GT3 bundle)
- Motherboards: GH-012, GH-014
- First chassis to move all drive electronics to mainboard
- Also moves components from the smaller boards found in B/B' and C/C' to the mainboard, making the console have one single large board (besides the power supply)
- Almost identical to D-chassis and manufactured at the same time, but uses old GS (CXD2934GB)
- Battery on separate battery holder board
- Beginning with this chassis, consoles produced for the japanese market use the same chassis as others, and thus include the expansion bay and lack the PCMCIA-slot
F-chassis
- Models: SCPH-3000X R
- Motherboards: GH-015
- New MechaCon-revision in BGA case (this is NOT the "Dragon" MechaCon used from H-chassis onwards)
- Support for Rohm RTC+EEPROM (combined) chip, although some consoles also came with the old dedicated RTC and EEPROM chips
- Drive uses Sony KHS-400C, KHS-400R or Sanyo SF-HD7 laser, as do all drives until including I-chassis
G-chassis
- Models: SCPH-3900X, SCPH-37000 (japan only limited editions with blue-transparent or black-transparent case)
- Motherboards: GH-017, GH-019, GH-022
- New SPU2-chip with integrated DRAM (CXD2947R)
- Japanese SCPH-37000 (and some or all japanese SCPH-39000) have a different cooler, most likely to look less ugly through the transparent cases of the limited models
- For the transparent cases, sony even used a black flex cable to connect the buttons/LED-assembly
H-chassis
- Models: SCPH-5000X, SCPH-55000 GU (golden, limited Gundam bundle), SCPH-5500X GT (white, limited Gran Tourismo 4 bundle)
- Motherboards: GH-023
- Introduces the "Dragon"-chip, which combines MechaCon, SysCon, EEPROM and RTC
- New drive electronics based around the Sanyo LA6508, LB11971 and Texas Instruments SP3727D
- Removed the iLink port
I-chassis
- Models: SCPH-5000X, SCPH-5500X GT (white, limited Gran Tourismo 4 bundle)
- Motherboards: GH-026
- SPU2 + SSBUS-Controller combined into single chip (CXD2955R)
J-chassis
- Models: SCPH-5000X
- Motherboards: GH-027 (unconfirmed), GH-029
- Seems to be a rather obscure/rare chassis released only in europe
- Has a completely unique drive mechanism based around a PVR-702W laser
- Uses SP3751A RF-amp/front-end-processor for the laser in the drive electronics, just like every slim PS2 until including M-chassis does, probably to support the PVR-702W laser that is exclusively used in J-chassis consoles
Slim chassis types
K-chassis/LCG-chassis
- Models: SCPH-7000X
- Motherboards:
- Uses combined EE+GS-chip or dedicated Emotion Engine+Graphics Synthesizer chips, depending on motherboard
- Components of Network Adaptor included on motherboard (Ethernet-transceiver and SPEED-chip)
- External power supply
- Top-loading and completely reworked drive mechanism
- No expansion bay
- Above changes allowed for a much smaller and completely reworked case design
L-chassis
- Models: SCPH-7500X
- Motherboards:
- Uses combined EE+GS-chip or dedicated Emotion Engine+Graphics Synthesizer chips, depending on motherboard
- Introduces new PPC 405 based IOP with external 4MB DDR-SDRAM, which emulates functions of the old MIPS-based IOP as well as SPEED; has some compatibility issues
- As the functions of SPEED were integrated into the IOP, having an SSBUS-controller became obsolete, thus the combined SSBUS-Controller + SPU2 chip (CXD2955R) that was introduced with the I-chassis got "downgraded" to the older SPU2 (+SPU2 RAM) chip (CXD2947R), that was introduced way back with the G-chassis
M-chassis
- Models: SCPH-7700X
- Motherboards: GH-051, GH-052
- Exclusively uses combined EE+GS-chip
- Heavily reworked/simplified drive electronics (driver IC doesn't require any heatsinking anymore)
N-chassis
- Models: SCPH-7900X
- Motherboards: GH-061, GH-062
- Completely new chipset:
- EE + RDRAM + IOP + IOP RAM + SPU2 (+ SPU2 RAM, which was already integrated into SPU2 years before) combined into single chip (CXD2976GB)
- Dedicated GS again, but new revision (CXD2980BGB), which comes in a much smaller package and requires no cooling (besides airflow)
P-chassis
- Models: SCPH-9000X
- Motherboards: GH-070, GH-071
- Same basic electronic components as in N-chassis
- Different case design
- Reintroduction of an internal PSU
R-chassis
- Models: SCPH-9000X
- Motherboards: GH-072
- Removed the cooling fins which were still present in P-chassis. Instead, the EMI-shield now contacts the SoC.
- Most of the R-chassis consoles can not boot into FMCB.
PSX chassis types
X-chassis
