    I have also added a fan controller salvaged from a dead PSU.
    Do you have heaps of p3s at work?
    The design is pretty bad for modern 12V systems is it not?
    28A on the 5V rail, the 12V rail split to 15A and 7A.
    Does it really have two 12V rails? If so why when the 12V output is so low?

        It only has one 12V rail, probably 22A. All the yellow wires are in one group. They usually end up in P4-class systems where the 12V is used for the CPU.

            Can you read off the part numbers for the two diode packs for the 12v on the secondary heatsink there?

            I'm going to guess 2 16A, 200v fast recovery.

                I can read the one facing the transformers. It reads 16F20C3. The others are covered over by the coils and I don't really want to disassemble it.

                    They would have to be identical to function properly. I was right though, 2 16A, 200v fast recovery's. 32A combined, pretty good. I have a wintech 400W (a real 400W) that had the same thing on the 12v.

                        I load tested one today. It was fine on 316W. I increased the load to about 400W and it died a few minutes later. No explosions or fireworks, it just stopped working. I let it cool down and tried it again on a light load, but it was still dead.

                            Take out the diode packs and check for shorts.

                                Done. none found. same on the switchers.

                                    Testing ATX PSUs under load - Does loading the ATX 24 pin also load EPS & PCIE?
                                    by AJ847.63e
                                    Hi Folks,

                                    Just wanted to clear up a misunderstanding of mine (or what I expect is one). Isn't the 12V rail from the 24 pin, EPS and PCIE separated? IE if I put a power resistor on the ATX 12V pin that is not going to load, thus tell me if the EPS or PCIE rails are fine?

                                    I was recently watching ArIs from Hardware Busters video on how to properly test ATX PSUs without using 5 figure Croma substations.

                                    The PCB adapter he used breaks out the 12, 5 and 3.3V pins from the 24 pin and gives you banana plugs to connect to. That is a bit useless is it not? Aren't...

                                    Weird behavior on 3.3V rail of a CORSAIR CX600
                                    by bimole
                                    Hi,

                                    A colleague gave me an apparently ill CORSAIR CX600.
                                    He told me that he heard a banging noise, and smelt the magic smoke.
                                    After tearing down the PSU, no burnt component, everything seems OK, but the PSU often refuses to stay ON. When shorting PS_ON to GND, the fan spins a bit a finally stops. No output voltages.

                                    I tried to treat some apparently bad solder joins and finally it seems to work OK... on the 12V and 5V rails!
                                    It's another story on the 3.3V rail...

                                    Modding Two PSUs to Output 12V
                                    by RukyCon
                                    Hello again, this might be a bit of a far-fetched question, but is it possible to modify a 36v and a 48v power supplies to output 12v? Both power supplies appear to use the same topology, they both also have a dedicated 12v winding wired to the control chips, meaning that as soon as i change it so the main output is 12v, then the dedicated windings will not be able to output 12v, meaning it will not start up. However, if i were to then take the main output and tie it to where the dedicated 12v output would go, then it should be able to run fine?

                                    Anyway here is a quick overview of...

                                    by Xebozone
                                    I have a couple of these PSUs that have the exact same issue on both of them. I find it odd that they both exhibit the same Symptoms.

                                    When plugged into the PC, the PSUs are able to power the LEDs inside the motherboard (the standby 5v circuit I suppose?) But as soon as the power button is hit, the PSU powers on for a split second, then there is a (relay?) click and the PSU shuts off. Hitting power does nothing after unless the power is removed and then turned on again.

                                    I have a PSU tester which has the same results. As soon as the tester plugs in, it powers on for...

                                    Samsung 55NU6900 - Heard a pop then tv is dead, burnt cap & dead fuse
                                    by Pwtzz
                                    Hi All,

                                    Before replacing what I know to be bad even with my novice experience. What I have checked at the moment is the fuse and the obvious burnt capacitor. I haven't bought any replacement parts yet.
                                    I still have no idea how this happened but could just be plain old turned bad. What other stuff should I consider buying as replacement? thanks in advance.

                                    Edit: I saw that a replacement board can be had for about $50. I would rather attempt to fix before just replacement the board.
