Power Supply

Power Supply Unit (PSU)

All the PS3 models have a built in universal power supply and supports multivoltage (except some PS3 FAT models with power supplies LSEB1226B1, LSEB1254A1 or APS-227 that are rated as 220-240V input, so cant operate with voltages under 220V). 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.

PSU Model @ SKU compatiblity

Retail models

• As seen in the table below, the PS3 takes 100V-240V AC (with exception of APS-227, LSEB1226B1 and LSEB1254A1) 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.
• Watts = Volts * Amps (you are billed for total watts used over time by your local power provider)

Modifications and Repairs

Replacing the PSU

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 highest efficiency model that still satisfies the proper output power that your PS3 is rated for.
As a general rule all power supplies (not just the ones in PS3s) are most efficient at approximately 50% load, this is why almost all PSU models in the chart are rated for roughly twice what the PS3 draws under full load. EG. A CECHA/B draws approximately 200-220W when under full load using an APS-226, this power draw number is slightly higher when using the original ZSSR PSU which also runs notably warmer due to the fact that it is less efficient and therefore converts more of the energy into waste heat.

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: more discussion on the talk page. Talk:Power Supply

Externalising the PSU

This is usefull for tests, repairs, flashing, etc... (as a power source tool used temporally), or permanently with the purpose of reducing heat inside the PS3 case to avoid overheatings

For a permanent install is highly suggested to purchase plugs and/or sockets that will fit with the PSU and motherboard to create a proper power cable adaptor. Remember that normally inside the console the fan also gave the PSU a slight airflow, so is highly suggested to add a fan also to your externall PSU (although it wont have to run fast, its just to make sure heat does not accumulate).

The correct thick of the wires needed for the 12v plugs depends of the number of amperes (A) the PSU provides in the 12v rail, if you want to "play safe" the best idea is to exceed this requirement of the thickness of the wires by a lot (consider the full amperes of the 12v rail will travel along this wires, this is not the same case than a PC where the total amperes assigned to the 12v rail are divided in a lot of yellow wires so are thinner than we need for a PS3). As an example, oldest PS3 PSU's with 32A can use AWG10 wires, and newers with 13A can use AWG16 wires, for other intermediate models you can take a look here: http://en.wikipedia.org/wiki/American_wire_gauge#Tables_of_AWG_wire_sizes (the value of the "ampacity" column)

Please remember the obvious: Check with a multimeter to find which is positive and which is negative! (use a tester in continuity, and meassure wich plug is connected to the border of the PSU board, border is always ground), after identifying it you can use a permanent black pen to mark it to avoid forgiving it

Also ensure the connections are solid and or have no dry joints when soldering. All of this also applies when extending the white power cable from the PSU to the motherboard.

If you get the positive/negative the wrong way around the console will have a red standby light but will not power on

• Twisted wires (the guetto style, no connectors)

The way this is done is very simple, get a cable with a moderately thick AWG (Same thickness as a 110v/220v power cable) and strip off the shielding. This exposes the positive and negative cables, from here simply strip off the shielding of the two and twist the ends. Appropriately plug the correct positive & negative into the PSU (PSU's always has female connectors, cilindricall in FAT and plane in slim and superslim, is basically a hole where you can plug anything, even a cable without connector) and wrap the other positive & negative end on the poles of the PS3

• Alligator clips (temporal)

Alligator clips grabs anything with strengh (and good ones has a plastic cover that covers all the clip after grabbing to avoid shorcuts), are good but should be considered temporal

Perfect for PS3 FAT PSU's, use 4.5 milimeter "banana plug" ones, you can attach them to a wire permanently by using pliers and pressure

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.
