my ps3 has been down a while after i left it on the menu screen of a dvd overnight,then it wouldnt come back on,
as sony have been getting a bit smug (anti piracy,many terms and conditions, and the constant internet need)
i decided the last thing i was going to do was give them more money.(by buying an official replacement power unit)
i knew that pc power units work on the ps3 fat have been looking for advice on the slim version(to no avail),
it got to a point where i thought dammit im gonna make the leap of faith and make the connections to see if i will work.
,ps i went on a stag night just befor doing this so details are sketchy (dutch courage) if you kill your playstation you did it, anyway ,after successful power i read about the tendancy of the mother board to overheat so added a bunch of fans to the case.
tool list approximate . screwdrivers ph0 did most of it, there security screws to get into machine at the time i just used a slightly mashed flat-head driver,the machine holds together fine if the security screws are not put back(pic on next step)
a scavenged pc power supply
a soldering iron, (if your just doing power you could get away with terminal blocks, or even twisty wire and tape)
wire cutters strippers,
possibly a switch to turn power box on and off
for the fan stuff
dirty iron and plastic cutting things
nylock nuts and bolts, zip ties 4 holding fans in place
hot glue gun for securing stuff , (its non conductive and lasts for ages its great for making weak solderd bits strong)
optional fan control, switch or a potentiometer or thermostat , i used a temperature control kit, i think i should have gone for a pot insted but its done now.
allegedly attractive sticky back plastic i used chrome colour
scalpel with new blade
Step 1: This needs replacing
+12v @ 16A
+5.5v @ 0.9A
considering the cost of the official one and the relative ease at which it broke , a diy solution seems the only sensible solution.
Step 2: Select closest value
+12v @ 14A
+5v @ 2A
this part cost me nothing, has similar power output, and is the basis of this home made power solution to the ps3 slim.
Step 3: Pin selection
easyer to show on the power module as they have labeled the outputs for you. just solder your connections to the pins on mother board after checking what lines up with what.and cover your connections with heatshrink,
there is also 4 wires that connect the power supply to the motherboard. they have a plug at each end , unplug the end attached to the power supply and connect your wires to these wires , (much safer and easyer than connecting to the motherboard directly.
cut the needed wires from the plug and so on.
connect "acin_det" with "5vsv" they are both5v +
,"gnd" and "gnd" are - negative ,
"acdc_stby" is not connected,
"12v" is 12v+
i tried a couple of things to get acdc_stby working or connected to something as something but there is only so far i prepared to guess, it works without it. i guess its an neg -5 volt thing to turn the power supply on and off.
Step 4: Bench test
before cutting things i tested the set up with temporary connections.
Step 5: Extra sucky fan
ok so i got power , now i go all 'arts and crafts' .i also enlarged any vent hole to help the air through
Step 6: Connection. thermostat thing is not very good if im honest but at 12 volt there a bit loud , 5v is quieter
in hindsight a tune to taste pot would have been better, or a variable speed curve to match temperature curve.
Step 7: Extra exhaust fans, temp sensor in middle (green wires)
Step 8: Wireing diagram
ok so its been running all day and no problems, the maplin "temperature activated switch" kit is a bit either constantly on off, or on, or off, depending on how i put the trim pot.it is also avalable from middlesex university teaching recorces. the playstation model number is cech-2503b.
Step 9: Ameizera this is for you :-)

the temperature switch is a kit, i will see if i can get an image of the tracks if you want to go full on diy or make a improved controller , heres how i attached it, how do i explain easyer to do a picture, also find pics of enlarged vents,made the holes with my dirty soldering iron then trimmed up with a knife, by accident the trim pot is accessable through the small fan
