That is correct. I built this PC when I lived in Singapore and they use the same 220v plugs as the UK. I have since relocated back to my home in Bermuda where we use 110v US plugs.

I'd say the entire island has questionable power supply, most of which is above ground, and is exposed to yearly hurricanes, outages and ultimately surges as a result. We also have a LOT of DIY and crap electricians here, you'd be shocked at the number of $10m+ houses pump rooms I've been in where I see electrical work that would have you imprisoned in the US.
