For a 700Watt PSU (A lower Wattage PSU will give lower current values) Input: 115-230V 60/50hz 10A/6A, 60Hz/50Hz Output: +3.3V 22A, +5V 22A, +12V1 21A, +12V2 21A, -12V 0.5A, +5VSB 2.0A This is an adapter which can be plugged into a PC PSU unit. Does not matter if it has 20 or 24 pins works either way. We will get +12V +5V +3.3V and -12V All voltages are fused.
