How do i wire a series of computer fans to an AC outlets?

Im in afghanistan, and to pass the time, i find little projects to do. I would like to wire a series of computer fans into a 12v power supply, to plug into a 120v ac outlet. what are the basic principles im looking for? like, what increases as i add more fans, and how much power is too much?

You can't plug the fans directly into the outlet, the fans are DC and the outlet is AC. When wired to a power supply unit that is 12V DC the fans would be wired in parallel, providing the fans are also 12V. For every fan you add the current consumption will go up until you eventually overload the power supply. Too much power is when it is greater than the design or current rating of the power supply. Connect one fan in series with an Ammeter and measure the current.How do i wire a series of computer fans to an AC outlets?
I must've mis-read your question, as it appeared you wanted to operate the fans directly from the 120 VAC line.

Just add up the current that each fan requires and keep that below the maximum rating of the 12 V power supply. You should be able to operate ~10 of them from a 1.2 A, 12 V supply.How do i wire a series of computer fans to an AC outlets?
It doesn't matter how many fans you add as soon as you plug them into a 120v outlet they will burn out. You need to have a reducing transformer thata will bring the voltage down to 12v.
