    While PSUs like this are not worth fixing to power a computer, as an Electronics Hobbyist, I find them to be a goldmine for various projects and repairs.

    I had a PSU back in my first computer that was even more gutless than the above PSU. When I scrapped it for parts (that is, I desoldered everything from it), I used the parts to fix many other PSUs and electronics. And I built almost my entire Senior Project in university with parts from that PSU. So it has been extremely useful and I am glad I had kept it over the years.

    Thus, if you are into learning or playing with electronics (be it as a hobby or a profession), you will likely find crap PSUs like the above very useful over time.

    Yeah, my thoughts exactly.
    I'll be surprised if it holds past 100-150 Watts of load.

      Well, up to a point. First, parts from such craps are too weak for any decent units. Second, when you have dozens of such, it gets just too much to diassemble everything (and what to do with so many components? ).

        I present the WORST PSU AT I've seen.
        In the photo that I measured the voltage, I almost electrocuted, because of the camera, I did not fix and I did not put the hand correctly with the tip of the multimeter. XD.
        Kids, do not do this at home xD.
        Going back to the subject, I find it VERY regrettable to leave a huge hole where the input of 220V DC ...
        In addition, the primary capacitors bloweds...

          200W from that? Not with those light weight heatsinks! And with just 220uF input capacitors the hold-up time would be horrible. The thing is over 20 years old, time to send it to the recycler.

            I also think the same.
            This source will probably pull it to the scrapping. But before throwing it I wanted to share photos.

              Absolute most of AT configurations won't even ever reach 100 W so the unit does not need to actually provide 200 W. That's why they went away with these craps.

                that might be worth $0.02 in scrap.

                  it will burn itself soon enough.and the pc,house,whatever its in.
                  nice puddle of brown glue right across the unfused side of the ac input.
                  nice firestarter.

                    Basiq 500 recap

                    This was a bitch. It used special-made 8x25 6.3 2200u caps, one wrapped in heatshrink was in particular bad area. I was not able to find any 8 diameter caps for the 6.3's so I had to use 10, and BARELY make it in there, but it was shorter, and I double shrink wrapped it cause it was in tight contact with a fet heatsink

                    Not user serviceable? surre


                    bad 3.3v


                    one of many


                    two extra


                    I love living right next to mouser (Mansfield TX, mouser HQ)


                    double heatshrinked panny


                    looks much better, don't you think?


                    passed


                    and in a C2D system working flawlessly, so there is no problem with handling a pull

                      8mm caps for Voltage Filtering are generally a bad idea...
                      And that FSP Plattform had its problems...
                      Though it looks like a newer revision...

                        FSP, most likely GLN platform. I can see GLY, yep, pretty much the same.

                        Though my new 1200/16 and 2200/6.3 D8x20 mm Rubycons make any Panasonics just a dogs food. You should consider sourcing some too, I bet I'll be cheaper even with shipping than all those overpriced corporations.

                                  Show a little grace, Behe. Many Americans are still getting used to Yugoslavia having re-Balkanized.

                                  That reminds me ... would a Yugo now properly be called a Serbo? A Croato? A Bosno? (Please! Not from Herzegovina or Macedonia!)

                                    I don't pay shipping for caps, I pay tax because they're bought in-state

                                    I also buy other stuff from them, I got a USB connector for a case, some other parts, a sata connector for a DVD drive controller board

                                        Yeah this platform is not that great, but if it's only two months old, it is under warranty, no?

                                            KDM 480W PSU upgrade succes! (opinions?)
                                            by bauto601
                                            Back in 2020 i bought a (2nd hand) compact ATX psu to replace my current one. My PC case only fits very short ATX power supplies so i didn't really have the choice of buying a decent 80Plus unit. The current unit is a modded YoungYear unit that i made a thread about a while ago:
                                            A "nice" YoungYear unit? - Badcaps

                                            The "new" unit is a KDM-M6480 480W psu, the 480W number is a typical KDM bullshit claim of course, but the 24A rating on the 12V rail seemed reasonable and the "Active PFC" claim gave me a bit of hope that this was going to be decent-ish....

                                            Introducing... the POS-124Z which really is a POS:

                                            Yep it's a POS allright.

                                            I tried powering it up. It's a KILLER - not fried, but sure will fry things! I got 21V out of it unloaded according to my DMM!

                                            I tried 21W load (car lamp) - got 16V, which is really pushing that lamp.

                                            Then I tried a 50W load (car headlight) - got 13.2V. Not too bad but this is with the heavy load...except the circuit breaker kept tripping.

                                            So I had to take a peek:



                                            EIEW. Looks like a Darlington emitter follower + Zener device. Heatsinking?...

                                            [LA-J891P] Warm cpu on 19v rail injection, is it fried ?
                                            by tamerelapute
                                            Hi,
                                            I'm learning electronics(already have some basics) by fixing a FH52M LA-J891P rev1B. It come from an acer nitro 5. The charger was defaulting upon pluging. The 19V rail resistance is 0ohm (I believe that caps screw my measurement). When i inject 5A, I get a rail tension of 1.3V, and 0.8V vcccore.
                                            Except the cpu, I cant feel anything getting warmer.
                                            I believe that it is normal, because the cpu is "eating" half the power I'm imputing.
                                            I dont know if the cpu is fried, because I did not remove the big capacitor on vcccore.
                                            I believe that if the cpu was fried,...

                                            Power supply ripple hall of shame
                                            by Per Hansson
                                            While our PSU hall of shame thread is fun I thought It'd be fun to have a ripple hall of shame thread too

                                            I'll go first out, it's an industrial PSU that offers +15v -15v -5v +5v rails.
                                            However it has been mounted on a frame with DC/DC converters for producing +12v and -12v as well.
                                            The caps for this have gone a bit high ESR
                                            The measured ripple is around 1700mV, or 1.7v!
                                            After recapping the ripple is gone, also note that the scale on the scope is 50mV/div instead of 500mV per div in this shot
                                            -And that's how you know you have a qualifying...

                                            Hello!
                                            Looks like I fried something when my EDP cable got squeezed on the hinge. I replaced the cable but still no display. Laptop works fine with external monitor connected through HDMI and Display Port-USB C port. I took it apart and I see a burnt component. Can anyone help me identify what this component is? I tried to use schematics for another G15 but it does not match on the amount of pins and size. I attached pictures. The component has a label on it - (21A29)

                                            Laptop is a Asus G15 Advantage Edition 2021 Laptop Ryzen 9 5980HX - 6800M...
