    NEC/TOKIN wants to know your location
    y9Z9j55.jpg In this tutorial, ill detaily explain, how to connect a ATX Computer Desktop power supply, into a PlayStation3, if you own a Slim or Super Slim PS3, if you are having power issues, and you need to determine if the PSU in your PS3 has gone bad.

    The procedure, may be complicated, but its pretty straight forward, and easy to execute, just follow the instructions, and double check if your connections are within they´re place.

    This Tutorial works with PlayStation3 Models:

    *CECH-20XX (1st Batch Slims)
    *CECH-21XX/25XX (2nd Batch Slims)
    *CECH-30XX (3rd Batch Slims)
    *CECH-40XX (1st Batch Super-Slims)
    *CECH-42XX/43xx (2nd Batch Super-Slims)

    WARNING: I AM NOT RESPONSIBLE TO ANY DAMAGE DONE TO YOUR PS3, ANY EXPLOSION,THERMO-NUCLEAR REACTION OR WELL-COOKED BOARD, DO AT YOUR OWN RISK!!

    ---------------------------------------------------------------------------------------------------------------------------------------------------------

    THINGS YOU WILL NEED FOR THIS MOD:

    *ATX Power Supply - (Enough to power the PS3, i used a 300W, but anything above should do no harm)

    *Cables - (You will need them to connect to the 12V and the 5V, preferably, isolated cables advised, power cables will do)

    *Electrical Tape - (This one its optional, but i recommend using it, into a few cables that are exposed, just to prevent any contacts, thus a short-circuit)

    ---------------------------------------------------------------------------------------------------------------------------------------------------------

    - STEP 1 - PREPARE YOUR PS3


    This its pretty straight forward, turn off the PS3, remove the HDD, and remove the screws underneath the PS3 Chassis.

    There are 7 Philips Head type screws, 3 underneath the rubber feet, 3 on the plastic feet and 1 on the HDD Bay.

    After that, remove the 4 Torx Security Bit screws, under the chassis,near the HDD Bay, once done, and all removed, the top cover, should come very easy, if it doesnt, double check, if you have any unscrewed screw left.

    - STEP 2 - REMOVE UNNECESSARY COMPONENTS

    Once the top cover has come loose, you can start removing the Blu-Ray Drive Deck, the WIFI and Bluetooth Anntenas (On the chassis and on the motherboard), and finally remove the Power-Supply.

    - STEP 3 - IDENTIFY THE ATX POWER-SUPPLY

    Grab your ATX Power-Supply, and look at the rating lable, see how much Wattage it can handle.

    PS3 Slims Power-Supplies are rated on an average of 250 Watts, no matter what model (APS or EADP), as you are going to use an ATX PSU, usually theyre rating are above 250W, so its good to go.

    For example,the PSU i´ve used has a rating of 300W total,but we all know the PS3 Slim doesn´t even reach this peak power consumtion, so no worries there.

    Very important, look at the 12V Connection, see how much Amps it can handle, a PS3 Slim PSU draws 16A from its 12V Connection, my PSU was rated at 15A, anything below 15A or above 16A its not advised, unless its over-kill, like 30 Amps.

    The PSU i had on my PS3 Slim (Model CECH-2504B) was an EADP-200DB, which has a rating of 250W, rated at 12V - 16A and 5.5V - 0.9A.

    - STEP 4 - PREPARE THE ATX POWER-SUPPLY

    Grab you 24-Pin Connector, and search for a green wire, once located, there are 4 black wires with it, 1 on the left of the green wire, and 3 on the right, once that its done pick a thin wire or a paper clip, and connect the green wire with the black wire (I suggest to connect with the first column of 3 black wires) this will create a Jumper (Jump-Start) on the PSU, when you connect it thru the power outlet, it will automatically send power to the PS3 Main-Board, thus entering the Stand-By Mode.

    Once you finished bypassing the 24-Pin Connector, choose 2 MOLEX Cables, to start working on the PS3 Power-Delivery.

    Grab your first MOLEX Connector, which will connect to the 12V on the PS3 Main-Board, and connect a spare wire to the YELLOW Cable in the MOLEX, which its the 12 Volt Income.

    On the same MOLEX Connector, grab another spare cable, and connect it to the BLACK MOLEX Cable, thats the GROUND INCOME
    (I Suggest connecting not on the 1st BLACK wire,next to the YELLOW one, but on the 2nd one).

    After you finished the first MOLEX Connector for the 12V, its time to move to the 5V Power-Delivery.

    Again, grab another MOLEX Connector, and 4 thin spare wires, you need to connect them cross connection on the MOLEX, simplifying it, grab 2 thin wires, and on the tips, twist them together, same with the other 2.

    Done that, grab your 2 thin twisted wires, and connect them with the twisted tips, on the RED MOLEX wire, which its the 5V Income, once done that, grab another thin wires with twisted tips, and connect them to the BLACK MOLEX wire, which its the GROUND INCOME.

    - STEP 5 - CONNECT YOUR ATX PSU TO THE PS3

    After you´ve done working on the 2 MOLEX Connectors, and the 24-Pin Jumper Bypass, its time to connect the MOLEX Connectors, into your PS3 Motherboard.

    Grab your MOLEX Connector which contains the 12V Power-Source, and the YELLOW wire you connected before, and on the connector on the PS3 Main-Board (The two long sticks) where goes the Original PSU when inserted, connect the YELLOW 12V wire, into the first connector.

    Once done that, grab the BLACK wire, on the same MOLEX Connector, and connect it into the second 12V connector on the PS3 Main-board
    (The one closest to the exhaust vents)

    After you´ve connected the 12V Source, its time to move to the 5V source, again, grab your MOLEX Connector, that has the RED 5V and the BLACK GRND Cable, which you´ve twisted the tips and connected into they´re respective wiring colours.

    Grab the 4-Pin Connector on your PlayStation3 Main-Board, and straighten the 4-Pin Connector (this its very important, as it helps connecting the 5V and the GRND into they´re respective connection holes), once done that connect the 2 thin RED wires on the MOLEX into the 2 holes on the EDGE of the 4-Pin Connector.

    Once done that, grab your 2 remaining thin BLACK GRND wires on the MOLEX,and connect them in the 2 middle holes into the 4-Pin Connector.


    - STEP 6 - CHECK IF EVERYTHING ITS WORKING

    Once done, plug the ATX PSU into the power-outlet, and the PSU Fan should kick-in, and the PS3 should be in Stand-By Mode, and check in your PS3 Powers On.

    ««CONGRATULATIONS YOUR PS3 ITS WORKING!!!»» :D:D

    *Q&A - Other Sympthoms

    #1 Q - My PS3 won´t show any light, or will not power on!?

    A - Re-check the connections, make sure everything its properly connected!

    #2 Q - My PS3 still keeps shuting down, everything is connected properly!

    A - Unfortunately that means its a Motherboard problem, it could be the Capacitors,Mosfets or even the NEC/TOKIN Power Capacitors that needs a replacement, since they are related to the Power Delivery.

    #3 Q - Its there any way i can check if its the Caps or the NEC/TOKIN!?

    A - About the NEC/TOKIN, you could try to blow some hot-air with a hair-dryer on the main-board, just to simulate a machine under use, it worked on my old TOSHIBA Laptop board, with a similar NEC/TOKIN Power Delivery, but personally i never tried on a PlayStation3, the Caps, needs to be checked for the proper voltage.

    #4 Q - Its using the ATX PSU on a PS3, safe for long periods of time!?

    A - I would not advise to stay forever with this mod, as i used mainly to troubleshot my CECH-2504, if your PS3 turns on properly with this mod, and its stable, then a rapid PSU replacement its advised.

    #5 Q - Did you fixed your PlayStation3 with this modification!?

    A - Unfortunately no, as my CECH-2504 didn´t manifest a PSU issue, as i initialy though, so i am calling it a day, it served me well though, so i no big loss there :D

    #6 Q - Will this mod work on a "Phat" PlayStation3!?

    A - Well, this Tutorial was made for the Slim and Super Slim,since the wiring layout its identical, the PlayStation3 "Phat" 1st-Gen, has a 5-Pin or even 3-Pin 5 Volt Connector, so i don´t know how to connect the 5V there, but i do know there its a batch on 80Gb PS3 (NON-BC) which has a 4-Pin Connector layout, similar to the PS3 Slims.

    Credits goes to Sandungas, for helping me troubleshoting my dear old Slimmy, as he gave me the idea to do this Tutorial :D

    Cool, it was needed a tutorial about this, every X time appears someone in the forum with PSU problems, and this is very handy to identify if the problems comes from PSU

    I moved the thread to the hardware subforum that fits better
    And there are a couple of things i would like to comment, im not telling you to modify your tutorial, but this is a good start point to talk about other variants, and other details to make this the best "ATX to PS3" thread ever made :D
    There are many variants because the goal can be different, if someone wants to make some kind of case mod with a PS3 motherboard + PC chasis case + ATX + heatsinks + PC FAN, etc... and use it like that then there is needed to calculate things well and try to solve all the problems, so there are lot of things to talk about
    For a simple test there is not needed to be that picky though, by now this tutorial is the basic, but i would like to mention a couple of things, i was not sure how to explain them, so i made a drawing
    [​IMG]
    In the drawing i say a single wire of a ATX PSU is rated around 6A because i found it while reading this:
    http://www.instructables.com/id/A-Makers-Guide-to-ATX-Power-Supplies/
    I was not aware about how much it was... but i gues we can take this "6A per wire" as close to the standards
    The reasons why the wire doesnt melts in the videos and other tutorials i found in internet where they uses a single wire is because:
    -We are reading the power in the PSU, but usually the PSUs are overpowered and the PS3 power requirements are lower... in this example with the 16A probably the motherboard is around 12A or so (this is speculative, hard to know how much)
    -That 16A are the max in the worst scenario posible (with all components of the PS3 working at full and inside a game, with hdd and bluray spinning etc...) but when you turn ON the PS3 the power requirements are way lower
    -The plastics are not going to melt instantly... this is something that requires half an hour or more to cummulate the heat
    -All this depends of the quality of the wires of your ATX PSU. And the wires have a security margin too, lets say if the wire is rated at 8A (a good one), and the real PS3 motherboard requirements are 12A (a bit smaller that what the original PSU says)... then is posible that the wire resists the heat and doesnt melts

    Oh thanks for the modified schematic mate, i made the previous one on a bit of a rush, since i took almost 4/5h to write this tutorial, step by step, to make sure not a singe detail was missing or a mistake, was made.

    I took the courtesy and replaced my crappy scheme with yours which its more detailed, if someone has some trouble with the tutorial,they can easily guide them through your schematic

    But i am always glad if someone wants to add or help

    Thanks to you to start this talk :)

    The same rules applyes to all PS3 models i think... the differences are the pinout of the small connector... and of course the watts of the original PSU (the first PS3 models CECHA, etc... had a big PSU)

    But dont replace your image by mine, yours was better :)
    What you can do is to include some of the details i added (but no need to include all the texts i wrote in it)
    The connector pinout i used in the image was taken from here btw http://www.psdevwiki.com/ps3/File:SlimPSU-pinout.jpg
    And if someone is interested to see how is located there is a list of motherboard revisions photos here. In the slims is the same connector, but the position changes, and sometimes is rotated www.psdevwiki.com/ps3/Motherboard_Revisions
    And this could be useful too http://www.psdevwiki.com/ps3/Talk:Power_Supply#How_it_works

    OK, we will make new images XD
    What i think is in the first message of the thread (the tutorial itself) you can show the most simple and basic wiring (intended to make a test)... like in your original image, but removing the 2 small black wires at the center of the small connector because this way is even easyer
    Try to make it simple, and stay limited to that, if at some point someone posts the wiring for PS3 fats you can include it later

    And the other details (like what i said about being carefull with the wires sections because the wires could overhear) can be discussed along the thread, no need to add this info as part of the tutorial because is going to make it longer. There are a lot of videos in youtube of people doing things like this with a single wire of an ATX... so for a short test of a few minutes i guess is ok

    So done a bit of searching, and i might found a solution why the PS3 its shuting down, because of 2 little bastards (capacitors) near the 5V 4-Pin, layout on the Motherboard, since my Board its JSD-001 and the guy mentioned a JSD-001 (CECH-2511A)

    One of them its shorten, but i have to test the 4-Pin 1st, to know for sure! If its is, removing them should get the job done.

    I doubt its the NEC/Tokin´s the cause of the trouble

    Great work guys. 2 questions though. 1. On the picture with the 4 pin connector you only show the 2 red wires going to pin 1 and 4 and nothing about the 2 black/ground wires that you said go into the 2 middle slots as pointed out in the actual guide....so do I still need to put 2 grounds in the 2 middle slots....or no?
    2. About the 12v rail and the wires roughly only handling 6a apiece....do I need to take 3 yellow wires from the atx molexs to achieve roughly 18a?? I noticed no talk about this other than the info in the pic?
    Thanks again guys. This is for a test run on my cech-4001B, as i believe my psu blew.

    Well I got everything hooked up. When I flip the power switch on the atx psu it starts up fine however the ps3 does nothing other than the heatsink fan clicks on for a very brief moment. Then nothing :/ any ideas guys?

    Are not needed
    The GND of the small white connector is connected internally (inside the motherboard) to the big metal post that enters in the PSU (GND too). So you only need to connect 1 GND, in the schematic GND is connected to that metal post but you can connect it to any other GND (such the copper border all around the motherboard, thats GND too), is just the metal post of the PSU is better
    The other pin of the white connector is related with the power ON/OFF button, but in this schematic we are ignoring it... is not mandatory because you are going to turn ON the PS3 by bridging the green wire of the ATX connector (or by using the switch at the back of the PSU)

    It was a rought calculation, every PS3 model has different requirements, and after this talk i realized usually the ATX wires are rated a bit lower (less than 4a), so is hard to know how many are needed
    What i have clear is if you want to "do it well" are needed more than 1, lol, thats for sure, but this is mostly intended for safety and incase you want to make an intensive use of it, also is needed to consider the PS3 requirements varies, when you turn on the PS3 (on main XMB) the power requirements are not much high, the peaks happens inside the games
    But if you look in internet for this mod you are going to see lot of people doing it with only 1 wire... so.... ok it works... you can do it but be aware of all this
    The spot that are going to overheat more are the connectors --->male-female<--- because adds some resistance... so in the schematic the "hotspots" are going to be the molex connectors
    You can touch the molex connector and the wires with your fingers while working to know if are overheating (is just 12v, not harming)

    Not "beeps" sounds, or leds flashing ?, nothing ?
    The PS3 has a "fantest mode" (that starts the PS3 with the fan at 100% speed to remove the dust from inside), i have mentioned it before, not sure if a "damaged" PS3 is going to perform it successfully, but you can try it

    PS4 should have the same board layout as PS3, but i wouldnt try it, unless you do some research first ;)

    To be honest I still didn't understand steps yet. It would be great if someone can put an image for the super slim ps3 like the one for the slim model coz I don't want to damage my beloved console :d

    This tutorial its pretty straightforward, and simple to understand! You'll just have to help yourself a bit by reading and exploring the console and tamper with it!

    Ive made it as simple as it possibly can be, if you still don't understand, the forum members and veterans are always glad to help to answer your questions!

    This tutorial will work on Slims and Super Slims, both connectors are the same.

    Its the same tutorial as used in here, but if you cannot understand it by reading, you can use the YouTube tutorial you just saw, assuming you understand Portuguese (Brazilian)
