"The entire power supply is built into the PlayStation 3. The Xbox 360 requires an external "brick" that can be swapped out depending on the local regulations for electronic devices. The US and Japan uses 110-120V, 60Hz adaptors. We have confirmation from SCEA now that the power supply inside the Playstation 3 is, in fact, universal. The power supply supports 100 to 240 volts at 50 to 60 Hertz, which is useable in all modern power grids -- including Europe. Although European markers require a different physical plug for their infrastructure, there is no need to replace the power supply."
