PSU its an hp 0950-1977 , -15 +15 +5.2 +12 output , RCD/GFCI main house breaker instantly shut off when i plug psu
measured with ohm and diode all inputs of ac side and capacitors in filtering stage (lacking 3 caps in the picture 2 have small crack but not shorted)
so i measured also all diodes and mosfet and replaced the big caps was a bit leaking , i am thinking even not shorted the filtering caps
is the cause of fault but not sure. tested also all other small caps seems to be fine , today i buy new filtering caps , like this impossible to test
psu when plug breaker off.
