The Antec TRUEPOWER 480 provides +5V 38A and +12V 28A and +3.3V 30A and -5V 0.5A and -12V 1.0A and +5VSB 2.0A The total maxoutput is 480 watts 625 = (5 * 38) + (12 * 28) + (3.3 * 30) but 625 > 480 .... trying to recollect if it was a sin() or cos() ....... of how many degrees ....... and what to to with the negative voltages .... and then ...... Tilt! ..... Tilt! My minimalist recollection of high school electronics from 1968 permitted me to conclude that amps by voltage was easier for me to understand.
