There should be no need to add additional capacitors.
so are big caps bad or just unnecessary?
I suppose large caps act like shorts until they are charged
however the power supply should generally be sized properly to handle that ...
Basically are caps good or bad?
QuoteThere should be no need to add additional capacitors.Wrong, it depends what the load is. I had to add 10000uF to a good quality switch mode power supply when I was driving four stepping motors. These were switch regulated, without the extra bulk capacitance the surface mount ceramic capacitors on the chips burnt out from the current ripple.
The resultant spikes cause the ceramic capacitors to break down,
It's not a fault of the power supply
