    That sucks as it is the only obvious thing I can see.
    Looks very much like glue to me. They typically use glue on big capacitors and other large parts during assembly.

    Many times a fault is not visually obvious. Capacitors can also dry out, causing the same failure but no visible signs. Only way to check for sure is with an ESR and capacitance meter.

      Glue/RTV is also used for mechanical stability under shock and vibration.

        They have the Fairchild F, with no dash through the F and they just look cheap. I will post a picture of them later tonight
        Ahh yes, I have seen those! I pulled a pair of 13007's and 13009's out of a pair of YueLin YLP-013's. I just called them "Jairchild" as I could not find any manufacturer information.

        In fact, I just found them:

          Mine actually look different though, I couldn't for the life of me get a good picture of them with my phone but this is the best pic I got

            They are definitely fairchild parts you have there.

              It's weird though, the one you can't see on the left has a different style F than the one on the right.

                  This thing came in a case. CWT, you should be ashamed! This thing is so bad. No input filtering, 330uF input caps (They're actually 220uF) 13007's, one of the smallest main transformers I've seen in an ATX PSU, 16A for 3.3V and 5V. 10A for 12V. hardly any filtering, tiny output coils. Look at the grounding wire for the transformer This thing is just horrible.

                    Surprisingly the Sun-Pro built Thermal Master's are actually built better.

                    CWT really should be ashamed.

                        I presume it came out of a CoolerMaster case. In which case (pun intended), they too ought to be ashamed.
                        I love putting bad caps and flat batteries in fire and watching them explode!!

                          Yes you are right. What do you think it could do? I think this is a rare instance where the transformer would saturate before the 13007's would blow LOL

                              That might be even worse than that 420W Okia (also built by CWT).

                                  No beef! It's funny because if every one of the rectifiers on the 3 main rails was pushing their rated amperage, it would be just a hair over 250W

                                  Were they CWT as well?

                                  *general question* How come fast recovery rectifiers tend to have a higher peak repetitive reverse voltage compared to schottky's? Or is this not something that is very important if you were to replace a fast recovery rectifier with a schottky?

                                    I'd give it 200W without blowing up, but nothing at all with the ripple in spec.

                                      The Okia had room for pi filters on all outputs and didn't have that one random strand of wire coming out of the transformer for grounding. How is that supposed to work?

                                        I was going by the heatsinks, and was a bit over-generous, maybe. I considered guestimating 235W, a common rating back in the late 90s.

                                          Please double-check tell me this really is NOT the grounding wire! If it is, it would be absolutely ridiculous. Maybe a bad joke on CWT's part?
