Its not really practical, as the whole of the 1 Amp will need to come from the mains supply.From 230 Voltage AC to 12 V and 1 Amp DC supply
Not sure how you got that number, it's more like 11.5uF. More realistically you'll be needing more like 15uF, with a 400V rating.Also capacitor value for 1Amp, is very very high, according to reactance of cap X= 1/(2*3.14*f*C). We need X=230 for 1Amp current (I = V/X = 230/230 = 1). SO the capacitance goes 72kF!!
