I'm moving to Japan for a year and need my desktop computer for school and work. It has a large graphics card, motherboard, CPU cooler, and several fans, but I'm considering leaving the case behind and buying a replacement after I arrive. Would it be safer to disassemble and pack the components separately, put some parts in checked luggage, or carry the motherboard and graphics card on the plane? I'm also wondering whether antistatic bags, bubble wrap, and clothing are enough protection. Finally, can I use my existing power supply in Japan with an adapter, or should I buy a Japanese PSU?

Several people have moved only the valuable components and then bought a case, power supply, monitors, and furniture after arriving. One practical setup is to pack the RAM, cooler, and accessories in regular luggage, carry the motherboard, CPU, and GPU separately, and purchase the bulky parts locally. It reduces the risk of damaging the system and avoids hauling a large case across the move.
Check the label or manual on the PSU before deciding. Japan uses 100V power, so the supply needs to support that voltage; many modern units are rated for a wide input range such as 100–240V, while some are not. An adapter only changes the plug shape and does not convert voltage. Also, don’t remove the ground connection just to make a plug fit. Use a properly grounded outlet or suitable surge protection where available, and replace the PSU if its voltage range or plug compatibility is uncertain.
If you still have the original motherboard and GPU packaging, use it. Otherwise, put each component in proper antistatic packaging and surround it with rigid protection and clothing or foam so nothing can move around. Don’t let bubble wrap or other ordinary plastic touch the electronics directly unless the parts are already inside antistatic bags.
The motherboard and graphics card are the parts I’d prioritize for carry-on luggage. Keep them padded and make sure airport security can inspect them if needed.
