PAL console and computer voltage question

[ataridave]

So Mark, on Classic Game Room, had an episode where he got a PAL slim PS2. And all he had to do to get the right power into the console was swap out another 8.5v slim PS2 power supply, and not use a voltage step up converter. What confuses me about this, is that I was under the impression that ALL PAL hardware, whether it be a gaming console, or a computer, requires 220 volts. Is it just the "newer" hardware that doesn't?

a lot of modern switching supplies have a rating from like 90-240 volts, and on higher powered industrial or computer types there's a toggle switch to choose, the sony suplpies are on the oddball side, once the power leaves the supply its low voltage DC, doesnt care where it comes from

 

in power supplies that use transformers the output would be 2x as a 110 supply, if it doesnt burn up, and in some cases where the device is using the AC wall frequency like old TV's and radios, the difference tween 50-60Hz will mess with the operation

So the PAL slim model PS2s are exceptions to the rule? As far as voltage step up converters do, I don't want to spend a lot of money-this one looks solid: http://www.220-electronics.com/100-watt-diamond-series-deluxe-voltage-converter.html

there is no rule, you have to look what the power supply puts out

 

if it wants 220 in and puts 220 out, you need a step up, if it wants 110 in and puts 8.5 volts out you can run it off a 9 volt battery, it dont care cause its low voltage DC at that point
