Hi, before you plug that O2 not sure if you already do so.
I also live in a 220v country at first used a 110-220v step down converter for the O2 and Octane and they worked fine.
One day i realized that the PSUs where universal so i decided to get rid of the step down converter an plugged them to the wall.
The power supply's on my o2 and Octane blow up and give out lots of smoke, they where dead i have to order new PSUs from Ebay.
From that day i always used step down converters on my SGIs.
