There is really no need for one eg: 120v to 100V

I thought America was 110v? I have a US step-down transformer and it says 110v on it. Anyway, I use this transformer to play my Japanese consoles, no problems at all.

The nominal voltage is 120V, what you actually get is slightly more complicated.

http://www.faqs.org/faqs/electrical-wiring/part1/section-14.html

In the UK we've officially changed to match the rest of europe, but the reality is slightly different

"In the UK the nominal supply voltage is 230 -6% +10% to accommodate the fact that most supplies are in fact still 240 V"

Amperage is a draw, which means you can use the amp value as a minimum value and need not be exact. It will only use as much as it needs. It is voltage you need to match up as close as possible.

Not really. If PSU is regulated, then a few more amps won't make any difference, for example 3A instead of 0.5A means only that PSU will heat less.

I decided to bump this thread, because I recently purchased an FM TOWNS II HR model computer and it sometimes powers off when running it through US power without a voltage converter. I did some research and I keep bumping into this:

I asked "batteries plus bulbs" store and they said it's not necessary to use a converter, but how do you explain the FM TOWNS II HR powering off by itself?

Bad power supply most likely bad capacitors. Have it looked at.

the psu will run in the 100v range fine ie: 100/110/120v it's within the 20% tolerance.

Just like any PC, turning itself off is indicative of a fault. It's probably doing it for safety reasons. It could be the PSU, but it could also be something telling the motherboard to shut down. Heat sensor, fan sensor, bad caps etc.

If a Nintendo Color TV Game system is designed for an Output of 9 DC, would, let's say, a 10V DC Famicom or Sega Genesis/Master System adapter be ok to use with it?
