I think the question is "HOW DOES HE RUN A COMPUTER". The answer is simple and was given before. He gets himself a universal power supply. That is an oscillator driving a transformer where feedback is used to regulate the output, not the input voltage. First invented by Philips, called SOPS (self oscillating power supply) and works between 90 and 260V. I bought one at a computer meet in Melbourne 650W at $72 about a month ago. but check on line Im sure you can find them . The supply is sealed so you are only plugging in 12V, 3.3V etc so its unhook the old and plug the new. If the computer is new it will be sata. My advice is, find out what your mother board is, google that and get a copy of its connections, then look for a supply. The arguement as to what the eye see's. Well the PAL system in TV was developed because the eye can detect an error in flesh tones at about 5% and a variation in brightness at about 30% so the PAL system turns a colour phase error into a luminance error which can not be detected
