Switching multi voltage power supplies have electronic parts that can handle input AC voltages from 100~230v and deliver the DC voltage desired by the device. The AC frequency is unimportant, since the DC voltage that all the internal components are powered by has no frequency, since, you know, is is DC.
The video sync frequency has nothing to do with the AC input voltage either, mainly because the video sync frequency is usually generated by an oscilating crystal of some sort.
It's not a multi voltage power supply. My csy2100 is 100-240v input and 50/60hz. His Wii pal PSU is made to receive 230v 50hz and outputs the same DC current amp load.
If he severed the cord and installed a U.S. 120v cord, the PSU would not be able to "adapt" the 120v current to output to the DC current as all Wiis run on. He would need 240v receptacle and a step down transformer to fix the input timing so he wouldn't under run his capacitors and blow his PSU.
the difference between 60hz 240v and 50hz 230 volt is your loading your current at 10 more volts 20% times more per second.
You may be right that the sync is not determined by the input, but why does pal Wii support 60hz sync timing in certain regions? Does it detect 60hz displays or does it detect power input?
