      My PSU i believe would not be able to withstand a load of 1w hahaha

          That isn't even that bad of a PSU. It's just really old and uses junk caps.

              this Airis is very poor quality. A few years ago (2005) I had an equal to this, and the psu is garbage, because one day explode and shutdown the computer (2006).
              The KME, I do not know his quality, but the Airis the quality is horrible.

                Your English is fine.

                I know it's overrated and not the best. But with new caps and maybe a rectifier upgrade, I bet you it could easily do 250W in spec. And the SG6105 chip is better than the standard single TL494 half bridge unit. But I know that most people don't want to invest the time or parts to help such a PSU, which I understand.

                  I will, I have several quality capacitors, by get her back not i lose anything.
                  If it works, I will publish some photo the recapping.
                  did not know that was able to deliver 250w. i thought the PSU generic did not expect too much of it, but I was wrong.
                  Thank You
                  Bye

                  sorry, I was wrong, for I have been lucky if delivery 250w therefore worth repairing.
                  I thought you said in sarcasm mode.
                  Bye, thank You.

                    Oh, very cool! I really like the size of the PI coil on the 12V rail. Have you checked to see what the specifications are on the silicon on the primary and secondary heatsinks? With good enough secondary silicon, you can even get 300W continuous out of a 33 transformer, as long as the fan moves good air. You're on 230V, which helps.

                      not quite understand, sorry
                      You mean the mosfets?

                      I tried to look at the specifications, but I can not see it because it's all covered by the components.

                          Here you go:
                          Primary Heatsink (input zone): 2x d13009k, 1x stp20nm60fp
                          Second heatsink: (output zone) 2x FR1003G, 2x mospec s15d40.
                          I hope that this good, I hard to read, with all bothering components XD.

                            Are you sure? Googling it returns nothing.

                              FR1003G (without 408), rectified. I read it wrong, sorry.

                                Primary side sounds good. I'm guessing the two 10A are on 12V, and the 5V + 3.3V both get a 15A rectifier. Sounds pretty weak, it'd definitely need some better rectifiers on the secondary to do 250W continuous, safely. It could probably do 250W as is but would run really hot.

                                      No, I have no ESR/capacitance meter

                                      The welds appear well, but I leave photo:




                                      And fan:

                                      The fan is normally one of 8cm. Not if it's good.

                                        (8 cm fan is too small to remove the large amount of heat the PSU will generate.Something larger or at least a better brand will last more)

                                        La soldadura parece bien, no de la calidad de marcas Delta o Seasonic pero esta decente.
                                        (The soldering looks good, not likes the quality of delta or seasonic ,but still decent)

                                        Un ventilador de 8cm me parece un poco chiquito para remover el calor que va a generar el PSU. Si fuera algo mas grande o por lo menos otra marca que esa duraria mas.

                                        Pero yo lo repararia por lo menos para 200-250 vatios
                                        (Still i would fix it for at least 200-250 watts)

                                        (Y que viva España)
                                        Yes i love Nichicon MUSE Audio Capacitors...they would look awesome all over any motherboard

                                          My LG XC12 micro-hifi system was acting weird lately (sound from only one speaker) so I opened it to check. Found these little two Honsing gems inside its psu.

                                          One is obvious, the other is bulging also badly on top and on the circumference. Weird thing is I haven't found anywhere the missing cap body, and the unit didn't seem to be opened before, still had paint on some of the screws
