Hey, I've taken the plunge to get a japanese ceramic white PS3.
But anyway, I know that in previous PS3 models, the PSU has been universal, so you could plug it into any voltage supply around the world with a standard PC power cable and it will work fine. But since the White 40gb PS3's have newer boards inside and talk of lower power consumption I'd rather double check this is still the case for this new model, so as to not plug it in and experience the glowing warmth of a thousand exploding suns!
