I just wanted to mention that it is actually pretty incredible that nobody on the internet actually shows how to remove the power supply case. I'm not trying to break valuable shit here, you know?
Thank you, ToltecMerc. You're right about the value. I think as long as it's a resistor under 20 ohms that it's good to go. R5 is actually a Fusible Resistor. These regular resistors work but I'm going to look into getting the fusible ones for future repairs! Thanks for watching!
thx for the video mate. so as far as i understood r1, r5, the diode RBQ20BM65A , the mosfet sdt3n62k3 and the 43 kohm resistors are the most common parts which go bad? what are the values of r1 and r5? does DAP041 needs to be PQGL or can i use i.e. PYFH?
Hello. Have you tried to replace the R5 resistor with a cable only for testing purposes? I see that the necessary resistance is extremely low and being a safety component I think I could temporarily replace it with a wire just to test the rest of the circuit, what do you think of this?
Hey Legocrack1! I'm not going to recommend it but yes I have tried it and it did work for testing purposes. I used a 40 AWG wire. I actually put it through a full test with the PSU under load and it worked just fine. Again, I would not recommend it. Don't test with a large guage of wire because you may end up blowing more components on the board if you have a short. I've also tested with a fuse before too. That also worked for my testing purposes. I don't remember the specs of the fuse I used but it was a pretty low rated fuse.
@@AlphaBravoTech Hey thanks for your Quick response, I used a wire but still not working ha ha, I can measure just around 1V in 5V stand by output rail, what section or components of the PSU would you check?
Good evening, a question: I am a do-it-yourself repairer, and I have the problem that on this power supply, the 150MF 450V "C2" electrolytic was BROKEN. I replaced it and also replaced the 100MF 450V C1. I actually put them both from 150MF 450V. When the consol is restarted this time the C1 is BLASTED. What could have caused such a failure? To burst it will surely have a voltage of at least 500V .... I think ... Do you think that the power supply is repairable anyway? A "sight" there are no burns under or above .. Let me know, thanks!
I'm sure it could be numerous different things. Kind of sounds like a dangerous PSU to be working on and I would actually recommend to buy a new PSU in this situation.
Very good job, I appreciated it. Nice video. You tested on the beginning two resistors. R1 and R5. R5 has been mentioned here already, but R1, which was good in your video not. In some PSU I see color coding on that resistor, which I cannot identify. Is R1 0.22Ohms? Thank you.
Hi Alpha Bravo Tech, I am about to fix my power supply for the PS4 Pro, I am sure have to change de resistor 0.16ohm,the one you changed in the video. unfortunally it's nearly impossible to get a resistor of 0.16 ohm in the Netherlands, where i am from. I read in the reactions and there you stated that all are good up to 20 ohm. So really just 1 ohm, 2 ohm 3 ohm, and so on till 20 ohm, should do? And wat wattage should i use? Kind regards, Niels van Tongeren
I am checking your video everyday hoping that I will be able to diagnose mine and possibly fix it. I brought it to my uncle to check and we see that IC 32 is faulty. Do you know where to buy replacement or maybe different IC to replace it with? Mine is ADP 300FR. Thank you.
Thank you! That's the plan. It will be months from now but hopefully by the end of the year I will be doing daily videos. I'm actually about to post less videos for the next 3 months. I will still try and get as many up as possible though. Thanks for watching!!
My R5 Resistor (PS4 Pro CUH-7215B ADP-300FR) has a 5th color which is orange (brown, blue, silver, gold, orange). No calculators have that order listed as a possibility - so I can't get any info unless I select orange as the 3rd color (not 5th). Is this the same as the ones on these PSUs? If not, do you have any info regarding it?
Loud pop came from my Pro while in standby. No longer powers on; sometimes will beep/momentary blue light. Pulled out the PSU and nothing smells and board looks mint. Missing 5 volt power on both pins. Checked all caps, diodes and resistors and all test good. Mosfets maybe? I'm new at component level repair and just looking for some guidance. Thanks
Yes, maybe mosfets. Hard to say. Maybe DAP041 or DAP049 or DAP046 or whatever that ic is on that board (it will only be one of those on your board) (I don't remember all of them off the top of my head)
hello on my board is DAP041 PT GB, unfortunatelly iam not able to find this one on the market, what is the difference between others DAP041 mutations PTFJ/ PTGB/ PEEZ etc? Dos it matter to replace by exact the same DAP041?
Your video was great. I was able to fix the power supply to get 5v and standby 5v. But when I shorted standby and detect voltage, 12v showed up for a second and started dropping along with the 5v. I replaced dap046, dap012ah, and diodes. Do you know what could cause this?
Unfortunately, I don't. I have a couple here that are doing the same thing and I've been trying to find the time to troubleshoot them a little bit more in depth but I just haven't had much free time lately. Hopefully someday soon I will get some time and do a video on my findings. Thanks for watching!

Hey Juan! Pretty sure I got those on eBay but I also buy things from Mouser, Digikey and Arrow. Thanks for watching. I will try and zoom in in future videos once I get some better equipment.
My psu has an issue that none of your videos seem to have and I was wondering if you've experienced it off-camera.

Good morning, and sorry for google translator. Congratulations on the videos and repairs. I have a PS4 Slim that won't turn on, no sign of life. I tried to do a test on the power supply: With the multimeter on the 4-pin connector I find the two 5v, precisely 4.71v. Shorting the 5v and stand by I get 11.87v at the output of the power supply. The problem is that if I connect the power supply to the motherboard I can no longer find the 5V on the 4-pin connector connected on the board. Could it be the defective power supply? I thank you if you want to read and advise me. Hello from Italy
Hi, Claudio. Try to put a different "load" on the power supply. Maybe a 12vdc computer CPU fan or maybe a 12vdc car headlight. Connect that to the 12v line and see if your 5v is gone. If your 5v is gone then the power supply is bad. If the 5v is still there then it's probably an issue on the PS4 motherboard. I hope that makes sense. Thanks for watching!
Thanks for the video. I identified that the R5 was broken, so I replaced it with a large 5 Ohm resistor, but when I inserted the plug to test, it burned right away again. Any ideas what could be causing that?
Use a lower ohm resistor. I was mistaken originally and the original resistor is 0.16ohm. With that being said, it still shouldn't have blown with a 5 ohm resistor. Sounds like you have a short on the board somewhere. Probably one of the ICs or mosfets on the back. Thanks for watching! Good luck!
@@AlphaBravoTech Thanks! Do you know of any components that I could try and what values they should have when measuring? I cannot see anything burnt visibly.
Hey i have one where there looks to be no visible damage but there's nothing coming out of the 5V when i plug it in. not sure where to look, the fuse is fine, the resistor (R5) reads 0.5 ohms. wondering if that's the issue, or something else.
So far that sounds fine. Check for voltages on DAP041. One of those pins should be around 100volts. Another should be around 11 volts. Another should be around 5volts. Another around 1 volt and some change. If you're not getting those voltages on DAP041, try changing it out. Also make sure other things aren't shorted first like those two FETs on the bottom and the through-hole fets on the top.
@@moomilkboy on every one? wow. ok, try removing it and check the voltages again on the pads that it was sitting on the board. let me know what you get.
What does it mean if I have 12v on the output prongs when I put my meter leads in, before I have even jumped the pins on the connector?? My stand by voltages are present in the connector as well 5v each.
Hi Alpha, I got two with 5v absent. Where can I check for the 5v? I bought both used from two different places and I find it very odd that both have the same issue, no 5v present on the 4 pin connector.
Could be a few different things. Have you checked votages or changed out DAP041? Any shorted mosfets on the bottom? Its hard to say without testing it myself. I think I have another one or two with that same issue. Maybe I can try and do another troubleshooting video soon. Thanks for watching.
@@AlphaBravoTech Yeah that would be awesome. Yes, I have checked that IC and for any shorts on the fets. I don't get the 1v or something on the DAP041, just the 100v, 11v and 5v. Thanks a lot for all you do, much appreciated! Stay safe.
Can the 4 pin connector that goes from the power supply to the mobo go bad too? I messed up, after repasting thermal, and getting the ps4 back together. I placed the two big plug looking things together of the mobo into one slot of the psu. Instead of each one been put into one slot and it shorted :/ . I re did the trace that got burnt on the psu. But the white 4 pin connector wire looks burnt, a bit shade of black. The ps4 started fine just whenever i start a game it would shut off after a minute. Now it just beeps once, the blue light turns on but then shuts off.
@@AlphaBravoTech i THINK I NEED YOUR HELP YET AGAIN MATER BRAVO. i have a psu ADP-300CR AA and the two mosfets looks like they're shorted. R5 R13 & R14 RESISTORS ARE GOOD. now i tested the power ic like you toaght us and and some of the legs are beeping. Also, this power ic is the one that doesn't seem to have a second leg. my question is.. Are the mosfets reading bad because the power ic is bad? or vice versa. thanks in advance
@@bafurysutto8768 I'm going to guess that they're all bad but I could be wrong. Pull what you think is bad and test if off the board. Also, once you pull the components, check the pads on the board and see if the short is gone. Are you on Discord? If so, send you your username/tag. It will be easier to communicate and help you on there.
Alpha Bravo Tech. I really appreciate all the help. I just installed Discord on my phone as my username is ICANPHIXIT. And I will let you know what results I get from testing the board
You should test both power supplies. You should make sure you're getting the 5v and the 12v rails. If you are getting both rails, then yes, I would think that its a problem with the motherboard. Good luck!
I have a 300cr that does not give me 12V when i short AC_DET and AC_STBY. What could be wrong ? i replaced the DNP012AH chip but still the same i get no volts going to the optocoupler when i short thoes points any ideas what causing this .
@@chounglee5741 well repairing these supplies are more complicated some i was able to fix and some i wasnt.I guess its something to do with the pfc or feedback circuit. Iam also trying to figure these out as well
It sounds perfectly fine. You should test with a load on it though. See if you can get a car headlight hooked up to each side of that 12v prong and make sure it stay lit up for a few minutes. Get at least a 45w bulb.

Please help me!!! 🙏🙏🙏🙏 My PlayStation4 got zapped through the internet port But now it won't turn on it just beeps once and that is all Pls help how can I fix it???
Check the power supply first. Swap it with a known good power supply or test the one that's in there. If the power supply is good then it's likely going to be a board issue. You say it got "zapped" so maybe there is a shorted component on the board.
@@AlphaBravoTech ok I got another ps4 if I use its power supply to check if the one I have now is faulty what is the chance that I might blow that power supply?
Honestly, I have no idea what the chances are. I can tell you that trying a new power supply on a bad ps4 board has never caused an issue in the power supply for me.
@@AlphaBravoTech Ok thanks I really appreciate it and if it is something on the board how can I trouble shoot what is wrong because when I tried to turn it on it only beebs one and that is is no lights no nothing.Can you replace that part that have been fried or popped?
@@x-im-gxd-goofy3174 the easiest thing to check on the board is to check for shorts to ground on different capacitors and to just look at the board for physical damage to components. I can possibly fix the PS4 but I definitely can't fix them all. There are no schematics for any of the PS4 consoles. That makes repairing them a little bit more difficult.

Can the 4 pin connector that goes from the power supply to the mobo go bad too? I messed up, after repasting thermal, and getting the ps4 back together. I placed the two big plug looking things together of the mobo into one slot of the psu. Instead of each one been put into one slot and it shorted :/ . I re did the trace that got burnt on the psu. But the white 4 pin connector wire looks burnt, a bit shade of black. The ps4 started fine just whenever i start a game it would shut off after a minute. Now it just beeps once, the blue light turns on but then shuts off.
I haven't see that happen but if that wire is burnt, it needs to be replaced. Im sure there's a 4 pin replacement wire on ebay for sale.
I have continuity in one withe capacitor , but don’t know he value for replacement , like the one on the left showing on 20:22
Where could I get athat resistor discharge tool that you are using?
in ps4 also check the power ic .. its smd in the back ..
but be ware the board is so west for hotair .. it makes bubles on high tempreture
good luck
No worries.. I tracked it down.. Thanks again for sharing your knowledge
Sorry. I thought I replied to your message but maybe I didn't hit send. It was a 1/2watt and 500v.
oh and no problem. I try to share as much as I can. I watch many youtubers and learn from everyone too. Thanks for watching!!! 😁👍
@@AlphaBravoTech i THINK I NEED YOUR HELP YET AGAIN MATER BRAVO. i have a psu ADP-300CR AA and the two mosfets looks like they're shorted. R5 R13 & R14 RESISTORS ARE GOOD. now i tested the power ic like you toaght us and and some of the legs are beeping. Also, this power ic is the one that doesn't seem to have a second leg. my question is.. Are the mosfets reading bad because the power ic is bad? or vice versa. thanks in advance
@@bafurysutto8768 I'm going to guess that they're all bad but I could be wrong.
Pull what you think is bad and test if off the board. Also, once you pull the components, check the pads on the board and see if the short is gone.
Are you on Discord? If so, send you your username/tag. It will be easier to communicate and help you on there.
Alpha Bravo Tech. I really appreciate all the help. I just installed Discord on my phone as my username is ICANPHIXIT. And I will let you know what results I get from testing the board
could you link me to ebay or amazon where i can get the correct 16.2 Ohm resistor plz
They're 0.16 ohm. I was mistaken in this video.
Hi.
Sr. Can you tellme the value of the R1 resistor?
I’m not an expert by any means, but I think it’s 4.7k ohms 10%
Hey, I replaced my power supply off one from eBay and still nothing 😔, do you think it's the motherboard?
You should test both power supplies. You should make sure you're getting the 5v and the 12v rails. If you are getting both rails, then yes, I would think that its a problem with the motherboard. Good luck!
I have a 300cr that does not give me 12V when i short AC_DET and AC_STBY. What could be wrong ? i replaced the DNP012AH chip but still the same i get no volts going to the optocoupler when i short thoes points any ideas what causing this .
Did you find the issue?
@@chounglee5741 well repairing these supplies are more complicated some i was able to fix and some i wasnt.I guess its something to do with the pfc or feedback circuit. Iam also trying to figure these out as well
Hola la Resistencia original de que valor es y por cual es sustituida. Gracias
I did the test, this gives me 11.66v and sometimes 11.72, its fine?(PS4 PRO)
It sounds perfectly fine. You should test with a load on it though. See if you can get a car headlight hooked up to each side of that 12v prong and make sure it stay lit up for a few minutes. Get at least a 45w bulb.
what im trying to understand is the through-hole resistor is it 16.8 ohmsor0.16 and is it is0.16 why am I reading it as 16.8
You are reading on your multimeter in Kohms. Were you on 20k on your knob for resistance measurements, or your continuity tester?
nicely done
Thank you, Colin and thanks for watching!
please tell me that what is the R57 value?
The reading on top of R57 is 8201.
That would give it a value of 8.2 kΩ.
Hope that helps! Thanks for watching!!
In this video you answered my 2020 question haha
haha. nice! Awesome man! :)
@@AlphaBravoTech you are my hero, i can fix my ps4 pro.
amigo....la fuente de mi ps4 pro produce un ruido como si fuese un salto de corriente...o una chispa...pense que el ventilador estaba dañandose ...pero estoy ya seguro que el ruido viene de la fuente de poder...cual sera el problema
Do you have schematic of this board
Unfortunately, I do not.
Hi sr I'm Philip from the Philippine may ps4 power supply is no output in secondary tranformer and its cause no 5v standby and no 12v what should I check and what should I do to repair this powersupply i wish you read this and help me in my problem plss
R 0.16 ohm or R 16.2ohm?
Actually it's 0.16ohm. I was wrong before.
@@AlphaBravoTech ok thank you sir, i know this is R 0.16 ohm
@@AlphaBravoTech 2 watt right?
@@AlphaBravoTech My PSU died because of a mosfet short, then R became short
@@IDNFAMILY I'm not 100% sure if it's 2w. I know someone has told me before that it's 2w but I think the ones I have are 1w. I would need to verify though.
Where good places in Dallas that will accept my PS4 that has roaches 😬
To fix up I think my power supply is burnt from these lil bugs
@@guwop._5825 if it has roaches then it probably is the PSU. I do have a friend near Dallas that does console repair but he doesn't touch roach consoles. I know because he's sent me a couple of them for repair in the past. Sorry man. I'll take a look if it's not infested too bad. Send me a message on alphabravotech.com and I'll get back to you. Just make sure you tell me it might have roaches because I'll ask that you wrap it up in a plastic bag and stuff. I'll give you more info in the message. Thanks for watching!
Please help me!!! 🙏🙏🙏🙏
My PlayStation4 got zapped through the internet port
But now it won't turn on it just beeps once and that is all
Pls help how can I fix it???
Check the power supply first. Swap it with a known good power supply or test the one that's in there.
If the power supply is good then it's likely going to be a board issue.
You say it got "zapped" so maybe there is a shorted component on the board.
@@AlphaBravoTech ok I got another ps4 if I use its power supply to check if the one I have now is faulty what is the chance that I might blow that power supply?
Honestly, I have no idea what the chances are. I can tell you that trying a new power supply on a bad ps4 board has never caused an issue in the power supply for me.
@@AlphaBravoTech Ok thanks I really appreciate it and if it is something on the board how can I trouble shoot what is wrong because when I tried to turn it on it only beebs one and that is is no lights no nothing.Can you replace that part that have been fried or popped?
@@x-im-gxd-goofy3174 the easiest thing to check on the board is to check for shorts to ground on different capacitors and to just look at the board for physical damage to components.
I can possibly fix the PS4 but I definitely can't fix them all.
There are no schematics for any of the PS4 consoles. That makes repairing them a little bit more difficult.
reparar estas fuentes es casi que no merece la pena sin diagrama electronico es trabajar a palo de ciego
Why the hell did you turn away from the camera for the most important part, how to freaking open it. Thanks for nothing
Um, use your hands to grip each side and make one go in one direction and one in the other.
Which desolder you use? Can you point to store or name of desolder? Thanks
