i'm plannin on buying a ps3 but i want a specific model which only comes from usa.(80gb version) basically the power supply is just like a computers to it's a 3 pin kettle cable basically. so the question is if it is safe to use a standard UK cable and plug it into the US ps3 or do i need to get the plug adaptor as the uk power cable will nto work?. usa have 110v i think? and uk have 220v. so would it work without an adapter socket?
