I have a US Xbox 360 (E series, for inquiring minds). From what I've read on Microsoft's site, the 360 does NOT have a universal switching supply, but rather a 100-127V supply for US consoles (and presumably Japan, Canada, etc), and 220-240V supply for other countries using the appropriate voltage.
I'm looking at using a 220-110 step-down converter but have three concerns:
1) Power in Beijing is 220V/50Hz, correct? Will the Xbox 360 power supply care about the 50Hz/60Hz difference?
2) Will a 200W converter be sufficient? That should give 67% built-in overhead (the E series power supply is rated at 120W) but I want to be sure.
3) I will be staying in an apartment (not a motel/hotel); do most homes/apartments in Beijing have a universal outlet like this, or only the AU/CN type outlets like this? Most converters I can find online that are grounded (the 360 power supply complains if it's not properly grounded, and I feel more comfortable having such a setup properly grounded anyways) have either a US/NEMA plug or a Euro/Schuko plug and I need to know whether I might need an outlet adapter.
Has anyone successfully used a US console in a 220V/50Hz country with a converter? I know the games are region-specific, but will have US games with me so that's not a concern.
