well if ur gona spend so much money on ur pc, (ur sig) y not get a thermaltake psu or sumthing, real good qulity and more wattage, if ur gona be making a pc like that, i would get a strong psu.
i am getting a thermaltake PSU . . . purepower 560w . . . its just that for a little bit more, i get a 400W PSU FROM thermaltake . . . so i can at least replace that with a 560w and sell the 400w
