    Re: the gutless, bloated, and fried power supply hall of shame

    This was shawly not a 500W like it claimed to be. Notice the heat damage on the output. The wires were melted near the PCB. The funny thing is that when I peeled off the label with the SHAW brand, there ws another label claiming it was a Ritmo. Any ideas who made it? Maybe TaiwanBreakDownComponents Company? The heatsinks were OK-ish, but the 5vsb transistor was a total joke - about the same size as the one on kc8's echo star 480.

        I got a good picture of the wires. I stuck the 12v ones out (which were melted together) so you could see how discoloured they were.

            That looks absolutely horrible. Did the fan seize? If not, I wonder what caused the thermal runaway. It doesn't help either that they put big low-ohm loading resistors on the secondary.
            And, yes, you can tell the 5vsb transistor was undersized - note the burn marks on its spot on the PCB.

              The fan did indeed quit on this PSU, which is probably why it got so hot.

                You wonder why people don't notice their fans making hideous grinding noises.... A friend of mine had a 133Mhz Pentium and the PSU fan was in terrible condition.

                I did not know about capacitor problems at that time but luckily we just replaced the whole PSU.

                  They probably notice, but because the PC still appears to be working, they don't care.

                    Btw, here in Greece, I see many Linkworlds (LPQ, LPH or LPK) that use Sleeve Bearing Globe Fans and as they work at full speed all the time they fail quite often.

                      Sky 550 watt. It looks like TaiwanBreakDownComponents Company got the transformer right, for once as it's a real 35 size, but everything else is wrong. The transient input filtering is missing (other than only 2 Y-caps), the primary switchers claim to be 13009s, but they look too small. On the secondary, we have a 16A fast recovery on the 12v and 20A schottkys for the other two rails. All of the caps are BH. The primaries are 470uF. All of the rails have a pair of 1000uF caps on them, except for the -12, which has a single 470uF. The fan looks like an off-brand (HongGu). Probably could be re-built like my rexpower, but I'm not in any mood that at the moment, so it will probably just die a spectacular death on my load tester or get the sledge hammer treatment.

                        correct me if i am wrong, but it appears that the grounding pin on the AC connector goes nowhere

                        i would desolder the transformer out of it and find a junk small one to put in before you fry... the tranny might be good for a unit with a small tranny but good everything else

                        500w mein ezel, das ist sehr schlecht! (english: 500w my ass, that (power suppy) ist very bad!)

                          The ground wire does actually connect to the case. It's just not easy to see in the picture. But it is still a gutless wonder.

                              Shame. It didn't look that bad actually. Definitely not 500W, but I would have expected it to do 250W continuous, maybe 300W for short durations.
                              At least you got spare parts now .

                                Yes it did. It had no PI filter coils on the secondary and no way of adding them.

                                    Not sure. The primary swithers looked OK, although I didn't test them and they had gotten so hot that the plastic rings around the screws had melted. A few of the nearby resistors looked burned out, though. The burn mark is actually almost invisible on the component side of the PCB. Unforunately, I can't get any more pics as after it blew up, I scavenged the transformer and wires and gave it the sledge hammer treatment.

                                        Here's another shocker. Tiny transformer, miniscule heatsinks and half a PCB. The best part is, it's an FSP (more specifically, a Gigabyte "300W"). It did actually do 320W on the load tester, but the DMM wouldn't settle when I was reading the voltages.
