You don't need to redesine the circuit.What I did was making a 50hz sine wave generator (it's 220v here) producing 220v through transformer,and putting it to the input of AT PSU.This is very similar to inverter. There were a few problems:you have to use quite a big transformer because of large currents,and it makes some buzzing noise,probably because the generator didn't produce pure sine wave.
HappyPuppy:yes,it seems like you need a very powerful PSU.If you have some idea in electronics you can redesign the Sproggy's DC-DC to make it more powerful.The most current "hungry" voltages are 5v and 12v.If you know using Protel,you can add more 5v and 12v sections to the circuit.
