Very nice simple design. How to turn a cheap atx pwr supply into a powerful fully adjustable power supply. Are your two opamps basically driving the voltage limiting optocoupler?
@orcunziya2 күн бұрын
I have a 700 watt thermaltake psu and a psu tester that shows your voltage. As soon as I plug in the 24-pin socket, the blue light comes on for 1 second and it does not turn on (the tester works, I tried another PSU). I think the psu is going into short circuit protection. Do you have any ideas to redirect it? (There is no fan rotation, the tester light turns off after 1 second)

@@electronicshaverightstolive thank you I will try to return it to the friend I bought it from on Sunday. That's why I don't want to open the cover for now. But as far as I can see from the fans, there is no swollen capacitor. When I try it on the motherboard, the white LED on the video card in standby mode turns on. And when triggered, the video card fan moves very slightly. But there is no start and the white LED on the 6 pin of the video card continues to light. If the friend who sold it does not accept a refund, I will remove the cover and examine it. i will look into it

Thanks for the video. Have the same PSU for a HP Microserver N40L... it's dead. The chip you replaced seems good on mine (0.5V on the diode test). There's also 340V across the bulk cap so I think the HV primary is ok. None of the transistors appear to be shorted. The DC outputs aren't shorted either. I haven't figured out what is wrong with it. Btw, is the green wire the power good signal? Doesl jumping it to ground turn on the PSU?

I have a Gigabyte P650B with similar layout to the one you shown - PSU is giving standby voltage but wont start - no easily identifiable issues. Have checked resistors and diodes and getting unusual reading from the same diode that was a problem in your PSU. Hwr, mine is marked as HSR1060 STC (was unable to find datasheet online) - assuming same as SR1060 (not sure what STC stands for ? - assuming initial H is manufacturers marking ?) All in all getting voltage drop of 0.18V (which seems quite low) and OL in other direction as expected. Beep test is OL on both. When measuring resistance 0,6kkOhm in one and abt 380 kOhm backwards. Assuming diode is bad but not fully burned ? Hoping for some feedback. Thank you.

Sounds like the internal cooling fan is noisy. Those fans often go noisy on these fluke scopes. Also the charger input sockets fail often, too. I have several fluke scope meters and repaired the charging socket and fan issue on one of them with a video showing how I fixed it. Mine are colour versions of the fluke scope meters but very similar to the black and white screen versions. Lines across the screen is another common issue with that scope meter. If I remember correctly mine work off the charger without the battery installed. Well done repairing that one, good job.

Current regulation wasn't clear, what was the current regulating potentiometer connected to? Also, on a side note, something I've seen in another video, if you connect another double diode (half bridge of opposite polarity) in parallel with the existing half bridge at the main transformer output, you will also get a mirror of the existing voltage of opposite (negative) polarity. So, if you have 12v, you will also get -12v. Connecting accros the -12v point and +12v point will give you 24v output, basically, double of whatever voltage you have there.

@@electronicshaverightstolive Same? Wow :o I am pretty amazed. Many people in my country believed that broken parts are caused by planned obsolescence, lack of replacement parts, or just because of the belief that switching transformers and switching ICs were designed to break under too much tension from electrons. And also, fear of electrocution or explosion. I went to a local junkshop and they just gut out old boards and scrap them, so do the steel casing. Pretty sad when I see such, especially if power supply reached past warranty. Are there still people in your town who send their dead PSU for repairs and rely on your expertise?
