PSU compatiblity critisism
- The earliest batch of PS3 had the ZSSR5391A power supply, which as you can see in the above table draws a lot of amps from your power outlet. You can replace it with newer compatible power supply models that draw less power, and also produce less heat.
- The second criteria is to try to find the lowest input amp and lowest output amp that works with your PS3 model (for APS models, this means the higher the model number, the better).
The above is wrong in stating that:
- The output rating is a measurement for how much power the PSU itself uses (e.g. its efficiency)
- That it is better to get a PSU that has a lower rating which has littler headroom
I came here to say this and was glad to see someone else already brought the matter up. A lower rated PSU would in fact be worse if it couldn't supply sufficient amperage under certain conditions. In those cases, you could see unexpected behavior such as freezing, corruption and even intermittent YLOD.
Newer PS3s are more efficient than the original design. As a result, newer model PSUs have a lower rating as the PS3 hardware itself is not as demanding.
In most cases, you'll want a PSU rated at least the same as the one that was included with the PS3. Going with a higher rating would be optional, with the caveat that the PSU may generate a higher level of heat. Going with a lower rating should be discouraged.
Max Power ratings
(Corrected the max wattage information of the CECHGxx and CECHHxx models from 280W to 360W. I know this because I myself have a CECHH01 PS3 and the unit states the Current: 3A and Voltage: 120V on the back, therefore: 120V x 3A= 360W.) 67.71.80.71 01:07, 4 February 2015
- Note that 120V-only supplies don't exist. The highest currentrating is for the lowest supported voltage (which is 100V notated on the Power Supply powerrating label):
CECHGxx APS-231 : 100V-240V 3.5-1.5A 50/60Hz (350-360W) -> 79.2-81.4% | 12V 23.5A (282W) 5V 0.6A (3W) | total 285W CECHGxx LSEB1226B1 : 220V-240V 1.7-1.6A 50/60Hz (374-384W) -> 74.2-76.2% | 12V 23.5A (282W) 5V 0.6A (3W) | total 285W CECHGxx LSEB1254A1 : 220V-240V 1.7-1.6A 50/60Hz (374-384W) -> 74.2-76.2% | 12V 23.5A (282W) 5V 0.6A (3W) | total 285W CECHHxx EADP-300AB : 100V-240V 3.6-1.5A 50/60Hz (360-360W) -> 79.2% | 12V 23.5A (282W) 5V 0.6A (3W) | total 285W CECHHxx/CECHKxx APS-239 : 100V-240V 3.5-1.5A 50/60Hz (350-360W) -> 79.2-81.4% | 12V 23.5A (282W) 5V 0.6A (3W) | total 285W
- The SKU Models table has several issues: it oversimplifies information conveyed on other pages and it does not distinguise within SKUs of the variants available (as in the different PSUs used in them). Further it does not distinguise between maxi, peaki, maxo or peako (and if we would, if we would assume the lowest/highest or mean of each of them for the overal range).

Gap vs. Pitch
Gap is the space measured between 2 pins, while pitch is measured from pin center to pin center
How it works
Slims
- Based on a CECH-25xx... probably the same for all PS3 models using the 4 pins "CN101" PSU connector
- You plug PS3 power cord to one of your house wallplugs
- PSU switches on the 5v power rail and converts 100V-240V (input) to 5.5V 0.9A (4.95W output) and are sent to PS3 motherboard through CN101 pin 1 (5VSB)
- This 5v are converted to 3.3v and are sent to syscon, syscon checks PSU through CN101 pin 4 (ACIN_DET), if there is a voltage in it (around 5v) the PSU is confirmed working normally (otherway the PSU is faulty)
- Syscon turns on the red led next to the ON/OFF button to show the user that the PS3 has entered in "Standby" mode (but the fact is syscon was working in "standby" an step before at the time it does a check to the PSU)
- So everything is ready... now you press the ON button with your finger in the switch board
- By pressing ON/OFF button a syscon pin is grounded, syscon changes his operation mode from "standby" to "active" (this is speculative, but most probably), turns off the red led next to the ON/OFF button and turns on the green led instead
- Syscon sends a 3.3v control signal to the PSU through CN101 pin 3 (ACDC_STBY), while this signal is enabled the PSU 12v rail is enabled
- PSU switches on the 12v power rail and converts 100V-240V (input) to 12V 16A (192W output) and is sent to PS3 motherboard by a single "plug" (that metal pillars located vertically on the PS3 motherboard intended to enter inside the PSU)
- The whole motherboard is powered, PS3 turns ON
