Look at atx psu pinouts. Lepa have always fan turned on, so you just cross PS_ON with COM. If psu start, then you can take energy volt meter and chceck all lines.

I have already done this. The fan is spinning when doing this and I have tested power coming out of cables when doing this.

I have also tried to cross PS_ON with COM when PSU was pluged to motherboard, CPU, RAM. This resulted in CPU fan spinning but the all thing was not looking to be started.

The problem seems to be at the start
