PSU Help

- (Check your motherboard for this), does the large white ATX power connector have 20 or 24 pins (just count them), both on the motherboard AND PSU. Older = 20 pins, Newer = 24 pins, 4 more pins to feed the CPU directly.

Should be 24.

 Spoiler

Any idea on the voltage change? My hardwares most likely were manufactured in China with a view to be sold to Vietnamese market, thus it's safe to assume that they were made to use 220V electricity line. What I don't know is whether or not it matters what power voltage you plug in as long as your PSU is suitable for dealing with it.
Somewhat relevant.
Even more relevant:

You know...
*ZAP* ----220V ---> PSU#1 --xxV-----> hardwares
*ZAP* ----110V ---> PSU#1 --not enough power to run the PSU --/--> hardwares
*ZAP* ----110V ---> PSU#2 ---??? V-----> hardwares

PSU#1 is compatible with 220V power, producing appropriate amounts of power to operate the stuff
PSU#1 is not compatible with 110V power, unable to function
PSU#2 is compatible with 110V power, producing appropriate amounts of power to operate... what? Would this be suitable for the stuff up there?
