Allowance is +/-5% on the main rails, +/-10% on the +5VSB and -12V.

That means 11.4-12.6V for the +12V (though I prefer to see 11.64-12.36V)
And 4.75-5.25V for the +5V (though I prefer to see 4.85-5.15V)
I forget the precise numbers for 3.3V, though it has to be pretty tightly regulated. 3.2something to 3.4something I believe.
