    Maybe the PSU was heavily loaded, but the -12v was not, so it rose to over 16v and slowly killed the capacitor?

          Oh, Deer Me! Another Deer, It was branded "Mirage", rated at 500W. It's similar to the A-Power in Post 685. Let's have closer look at it.

          2A four diode treatment - check
          Tiny 330uF input caps - check
          13007 Switchers - check
          Very thin heat sinks - check
          EI-33 transformer - check
          Junk caps - check
          Two 3A fast recovery diodes on a bracket for the 12V rail - check
          Tiny secondary toroid coils - check
          No-name sleeve bearing fan with no oil in the bearings - check
          Big hot load resistors next to the secondary caps - check

          And I think that about covers it. Horrible design from the ground up.

          Sorry about the horrible picture quality. All I had was my tablet

            Oh man that is horrible. Does the fan still spin?

            Not able to supply a useful load in spec - check

            Interesting, it looks like all of the Su'scon caps are good. Did this thing kill the motherboard it was connected to?

                Yuck. I'm surprised they wasted input filtering on this thing. Those are actually decent looking Y caps

                  Yes, it does. It doesn't have any odd sounds either, although I've seen those same fans fail lots of times before

                  I noticed that. It looks like Yang Chun are worse than Su'Scon. No, it didn't take the board with it. I replaced it with an In Win IP-S400EQ3-2 and the PC was fine.

                  No, I don't have the label. I peeled it off and tossed it before I took the pics. I transplanted the innards of a Dell H305P-00 PSU into its case.

                    I'm surprised, and judging by the dust it ran for a long time. A drop of oil and it might last a while assuming the motor isn't on its way out

                    That's embarrassing. Although I think the Su'scon also would have failed had they been on the 5VSB

                    No, I don't have the label. I peeled it off and tossed it before I took the pics. I transplanted the innards of a Dell H305P-00 PSU into its case.
                    Nice! The case must have lots of holes in it. Is it not one of the classic flimsy aluminum-esque cases?

                      The case wasn't too bad. It had plenty of ventilation (similar vent structure to the one in post 685), and even screw holes for a front 80mm fan (which I installed, after cutting out the area in front of it)

                          Had a PSU like that. The lack of PI coils and missing caps made the PSU put out too much ripple even when powering a Pentium II PC!

                            That's pathetic! Was it a Deer as well? Let me guess, one cap per rail <2200μF

                              Yeah, it was my LC-B300ATX. 2200uF for the 3V and 5V rails, 1000uF for the 12V rail. But no PI coils. Hence the ripple. I added the PI coils and more caps in it right now. Haven't posted a picture nor tested it yet with a computer, but I'm sure it's better.

                                250W continuous would entail some risk of an incendiary event. 500W? For how many picoseconds?! I also noticed it has what appear to be safety agency rated Y caps (2200pF, perchance?), and also a common mode input inductor and a somewhat puny looking inrush limiting thermistor (were the rest of the thing not so pathetically wimpy and it really could supply 500W continuous, that thermistor might do double duty as a night light).

                                      Maybe those cheap junk fans could be used to clear solder flux fumes when you do solder work. Or maybe as a fan for test loads. Finding "replacements" won't be difficult.

                                        I agree with you, the fans are good enough only if we oil them, they can last a while, I'm actually very surprised that crappy power supply ran for that long on a computer!

                                          Pixxo PL-500RPG

                                          Weak Pixxo PSU made by Key Mouse. Looks pretty bad overall but it could be worse. The input caps are 820uF, I will have to see if they're actually 820uF. BR is 4A, those 2 Y caps are not safety approved. Uses fake Fairchild 13009 switchers.

                                          Main transformer is pitiful. Besides the input all the caps are ChengX.

                                          All the secondary silicon uses 20A schottky's for each rail. None of the rails have the option to add another in parallel. The toroids are small, missing caps on the secondary filtering. At least it has PI coils though... Fan is branded "kemex"

                                          Oh and look at the 5VSB transformer, there's a cut lead leg under the transformer sticker
