Can I use a 203 W power supply with a 200 W step-down voltage converter?

The question pretty much says it all. I have a 203 W 100-127 V Xbox 360 power supply and a voltage converter rated for 200 W. I am currently in India, where there is a 220-240 V connection (I'm not quite sure exactly which). Will the load be too much for the voltage converter or is this difference negligible?
