Hello guys,
I would like a quite old but still good 800 W ATX PSU to be repaired. The problem was an extremely heavy coil whine coming from the small secondary transfomer on the PCB.
I desoldered it hoping the references on the upper side would allow me to find a adequate replacement part. Sadly the written references drove me nowhere but to the manufacturer (I-MAG). I sent them a message like a bottle in the see asking them to send me a datasheet of the transformer. And... They responded ! I received a kind of datasheet (see attachment) but my competencies do not allow...

Unknown transformer : how to find a good replacement part ?

Hello,
Just a quick post to introduce myself.
I am from Belgium, computer scientist for 25 years and also IT teacher for 5 years now.
I learned the basics of electronics during my higher education but I never practiced it professionally. For a few years now, I have returned to it as a hobby. Now I repair more and more things and I have equipped myself for microelectronics (microscope etc.): I have managed to repair some laptops and motherboards, but I still have a lot to learn and that is what motivates me to be here.
KR,
