as far as I know the slimline v12+ have a universal power supply works from 110 -240v. The only thing you need is a cable from the plug to the power supply shouldn't be a problem. If you have a HDTV set then the ps2 will work because HDTV support PAL / NTSC. Only problem is only pal games will work if you got no modchip. So I'll recommend to buy a modchip or maybe go to best buy ask if you could swap your pal console for a ntsc one if you buy one 2 games.
