ofer, LMGTFY. ;-) Here is a direct quote "The power supply can operate on both 60 Hz and 50 Hz power grids. It uses a standard C14 IEC connector and a C13 power cord appropriate for the region it is being used in. The power supply on the "fat" model is capable of delivering approximately 380 W, although the PS3 has never been measured using this much power. The power supply was reduced to 250 watts in the 120 GB "Slim" model. PS3 Slim models have labels indicating localized input requirements for power (110V 60 Hz for North American and Japanese models and 220-240V 50 Hz for European and Australian models), however teardowns have revealed the power supplies are still universal" and here is the source and PlayStation 3 Slim Teardown so hope this will set your mind at ease. Good Luck and may the force be with you ;-)

I believe all PS3's (Slims, and Fats) have universal power supplies.

My understanding is that it was documented on the older PS3s to be universal. I have no personal experience at it, my understanding is that although undocumented the newer, including the slim are universal. I believe I caught this at both the BluRay forum and Llama's forums.
