Power Supply

Power Supply Unit (PSU)

All the PS3 models have a built in universal power supply, and supports multivoltage. What this means is that even though a specific voltage is written on the outside of the PS3, the PS3 can actually be plugged into any voltage anywhere in the world and work (as long as you have the correct cable). Therefore, if you opened up the PS3, the supported voltages should be stated (on the power supply) as 100V-240V, which is the range for all power outlets in the world.

Travel Transformers

Don't use an external transformer! Use only a passive travelplug, quote from the PS3 manuals:

Do not connect the AC power cord to a voltage transformer or inverter. Converting the AC power cord to a voltage transformer for overseas travel or use in an autmobile may cause heat to build up in the system and may cause burns or a malfunction.

As seen from the above chart, the PS3 takes 100V-240V AC (Alternating Current) at various amps (A) from your power socket, and converts this to two DC (Direct Current) voltages of 12V, and 5V (or 5.5V for later PS3 models) at various amps. 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. Less heat means less bending of the motherboard, less cracking of the solder, less fan noise, lower electricity bills, and no "Yellow Light of Death." In fact, for most models of the PS3, you can find a better power supply to replace the original. One of the main compatibility criteria is the number of pins on the power supply. It must match the number of pins on your connector cable. 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). WARNING: if you decide to replace your power supply, you do it at your own risk! If you don't know what you are doing, you may fry your motherboard.

note: there is strong criticism to above statement, see Talk:Power Supply

For those that are not aware: Volts * Amps = Total Watts used. You are billed for total watts used over time by your local power provider.

A sample breakdown of the CECHJ and later models finds a 261W Delta EADP-260AB power supply. It is fanless and all capacitors inside are made by Japanese companies: Chemi-Con, Rubycon, and Nichicon.

Note that for PS3 Slim models (CECH-20xx), there is no ground wiring support.

next to relais RY101 connected to 14pin IC303 "LM339DG # PBB636"

<jordosaxman> RV301  has 3 points, 1 of them goes to the solder point, one goes to the tiny resistor above it labeled 153
<jordosaxman> the third point is buried, no trace points on the top side, must go to the bottom
<jordosaxman> yeah it looks like RV301 hits a resistor and then goes to pin 3 of IC303
