Thank you for contacting Sony Computer Entertainment America LLC (SCEA) today Arpad. My name is Christopher, and I can definitely address your questions about your North American region PlayStation®3 system.
Please be aware that a North American PS3™ system only supports a power supply of 120V AC, 60 Hz. If you use your system in a territory with different television or voltage standards, it could damage your unit. We do not recommend traveling with your system and we also do not have any information about adaptors or converters to override any territorial restrictions.
Sony Computer Entertainment, Inc. (SCEI) has implemented a territorial-based distribution system for its hardware, peripherals, and software. This means that software or peripherals on a console designated for a different distribution territory than the console may not work correctly (e.g. North American games may not function in a system designed for other regions, such as, Japan, Europe, etc.).
You will only be able to play DVD's and PS3™ software titles coded "region 1" or "region ALL" coded in the NTSC format on the North American PS3™ system. Only Blu-ray Discs™ that are marked with "region A" will be supported.
