What I was saying in my other post is that you cannot go only by the wattage or amps, you have to take both into consideration for the best choice on output. After you figure what you need in terms of power you then need to find a suitable company to buy a unit from, with the extra features you want such as modular, pfc, low dba, etc.

ok so for a four rail psu you only add 3 rails together to get accurate picture of amp supply
but what do you do if its a two rail psu? is that still 75% of the total?
