Amps = Watts/Volts.
So 400 watts would be 400W/240V = 1.66 Amps. This only means the input usually. The output would be like 60-80% of this figure. Usually 250 watts would mean it needs a 240V supply at 1Amps. Providing like 20Amps 5V and 4Amps 12V. (100 watts + 48watts) with 50 watts going for the -12V, 3.3V and others.
