So here's what I think of the PS3

onna: you can just plug it into the socket. No one makes non-switching power supplies any more, it costs barely anything more to make it switching and it's much more expensive to have two separate power supply manufacturing lines. No modern electronics will break if you give it 240v instead of 100v, it will work just fine.

If you want to get your converter to feel safe then fine, but I wouldn't bother with it. Despite what the sticker says, the PS3 can easily handle 240v, I guarantee the power supply in the Japanese/US PS3 is identical to the power supply in the Euro PS3.
