      Found this little beauty in a Compaq Presario A64.

      Must have been a thoughtless replacement at some point for the original!

      Fan was very stiff so I guess it ran hot and somewhat overloaded for some time in order to cook more or less every cap in the unit!

        That might actually be worth a fix.

          I think I saw a March, 2001 date code on one of the caps. There's a good chance to original PSU was from Delta, and if it lasted for 15 years, it did pretty good. At any rate, while I wouldn't use that thing for the full rated 300W when brand new, restored it would probably be good for 200W-250W. The two potential limiting factors would be the 2A +5VSB and, more importantly, the 10A rating for the +12V output.

            The PSU predates the Compaq by some years without a doubt.

            I figured the person I acquired the machine off did a quick fix and swapped the PSU out for one from a older machine.

            Usually I am up for repairing such things but the weak 12V rail really means its rather useless for me in this system.

            Machine however is now sporting a 300W FSP unit and it working perefctly

              As far as my experience goes, I used recapped Deers similar to the Mercury above (except the diodes-on-bracket were replaced with actual rectifiers) to power Northwood based PCs. (in fact,one of the PCs I gave runs a P4 2.8 Northwood with a FX5200,a MSI 845E Max mobo and a 120GB WDC HDD)

                Oh Deer!

                It's one of their "2003"/"2005" chip-of-the-year BTX designs (BTX for Deer/L&C typically signifies the primary is located on the same side as the receptacle plug and the secondary is same side as the fan... not the other way around like with other "normal" PSUs).

                That said, with a better rectifier on the 12V rail and bigger output caps, this thing could probably provide up to 14 Amps on the 12V rail, which should be enough to power a Pentium 4 / Core 2 Duo / low power Core i3 or i5 system with on-board or low-power GPU and single HDD. I'm not sure if it's worth the hassle fixing it, though.

                I would do it for fun, but I don't expect anyone else to be like me.

                  The worst trash I could find, this PSU i was installed on a pc, the owner of the pc complained that it did not start all the time, and it squeaked, and it did not work stable the pc.

                  At least it has one good thing, it has 2 thermistors

                  The transformer is super tiny!

                    It's sad how that can be passed off as a 450W PSU. [I'm guessing 100W maybe.]

                    I like the brand of the input capacitors. [jay'long]

                      It will surely be 100W, As it requires power, it bursts xD
                      What is not as it has not yet exploded, nor the capacitors "jay long" xD.

                          I have thought, is to charge to burst, but for lack of machinery I can not do it .
                          I'll think of something like busting her xD.

                                  switch st stps30 45cw 30A (The only thing of decent brand xD)
                                  Actually, unless it's counterfeit, that KA3842 is either Samsung or Fairchild (Fairchild bought some of Samsung's linear IC products around that time).

                                  Those input caps (ignoring the non-brand brand) and the size of those heatsinks would put the realistic output power at around 250W maximum.

                                    I dare not touch a microwave transformer xD. What I want is petarla the 450w indicated, I will put several H4 light bulbs, to see if I can overload it.

                                        Thanks for this information, make it clear that it is the worst psu I have ever seen.
                                        I even put it at less level than deer xD.

                                        If the psu of the forum of jonnyguru exploded with 277, I do not want to imagine my PSU, since with a pentium 4 of 65w of consume gave error to start, I do not want to imagine asking for load of 277 watts, there it explodes in my face.
