An early microcomputer power supply was either fully on or off, controlled by the mechanical line-voltage switch, and energy saving low-power idle modes were not a design consideration of early computer If the motherboard expects two 12 volt rails (many dual CPU motherboards require one 12 volt rail per CPU) then it won't work. Power supplies label their total power output, and label how this is determined by the amperage limits for each of the voltages supplied. Some cards will refuse to run with only a 6 pin cable in an 8 pin socket. Source
