PC Connections

I plan to spend one month in Kuala Lumpur and need some advice. I am currently in Singapore and the cable connection between my PC and  the wall requires a special adapter to work. Since I live in Thailand, any PC I buy there or in the U.S. does NOT require a special cable or plug. Will a PC I could buy in Malaysia work if I bring it back to Thailand? The answer to the question Why not bring your Singapore PC with you to Malaysia? is that I'm using a borrowed PC here.

I have never had any problem using a Malaysian-bought PC in Thailand
