    Aerocool cylon 700watt Atx psu

    Hi
    Trying to find a schematic or info on a 7 pin dip ic that has exploded in my psu.
    One of the fets has also had blown.
    The top of the 7 pin ic has blown off into lower earth orbit so I'm a bit stuck.
    The ic is on the high voltage side of board.

    Pin 4 is not connected and pin 7 is missing as far as I can tell.

      I think it's a Tiny Switch type all-in-on regulator. The "missing" pin 7 is probably the spacing between pin 8, the output MOSFET Drain, and pin 6, the Source. Whether it's literally is a Tiny Switch or a similar product, I don't know.

            The first photo shows that they replaced the wrong PWM, it looks like TNY27xPN and turned it over.

              Your right I guessed and I was wrong.
              I can't seem to find the part you posted picture of to buy anywhere?

                    Before installing a new PWM, you need to check the entire wiring of this PWM - resistors, diodes, an optocoupler that is connected to it, if some component is not corrected, the power supply will not start or the PWM will explode again. The main thing is that the standby transformer would not suffer (interturn short circuit of the primary winding).

                      I've taken the exploded pmw driver back off board and the resistor which is open circuit I'll desolder diodes and check them next. how can I test optocoupler operation?

                        aerocool cylon 700w Zener diode identification

                        hi i have a zener zener marked c24 also t5 any one any idea of its value as its blown open circuit?
                        I have removed it from board to test.
                        It's out of a aerocool cylon 700w power supply I think it to do with a ic that exploded I belive for 5vsb.

                          Post a clear picture of the component, What case style? Are you sure it is a zener diode?
