Minimig needs max. 150-200mA without PS/2 components.
With keyboard and mouse the PSU should provide at least stable 500mA. 1A and more are just for reserve and additional stabilizing.
Maximum power consume (200mA) is for about 1.5 sec while the FPGA is "booting". After uploading the firmware (minimig1.bin) the FPGA will internaly checksum the uploaded binary. this takes more power then normal operating but just for a short time.

That seems like a bit high? From Acube:
[color=ff0000]Power: +5VDC (approx 100mA without mouse) [/color][/i]

A standard keyboard would require 50-mA maximum (with three LEDs ON) and mouse would max out at about the same. I'd say 300mA would be sufficient.

I dont know who wrote this, but this one never really measured the current. I did it using a laboratory power suppley. There is a maximum peek of 200mA only while the FPGA is booting (short after loading up the minimig1.bin and 1st reset).

Interesting findings :-) What was the supplied lab voltage, I mean specifically (110V/120V/130V etc).
