Power supply unit for a computer system and arrangement having a corresponding power supply unit and a computer system

Abstract

A power supply unit for a computer system including a first converter circuit with a first control circuit that converts an input-side electrical supply voltage into at least one first output voltage, a second converter circuit with a second control circuit that converts the input-side supply voltage into at least one second output voltage, wherein an output of the first converter circuit directly electrically connects to an output of the second converter circuit, a nominal level of the at least one first output voltage is higher by a predetermined voltage difference than a corresponding nominal level of the at least one second output voltage, the power supply unit includes an additional circuit on the input side of the second converter circuit, which additional circuit controls the second control circuit such that the second converter circuit operates with a minimum output power when the first converter circuit provides the at least one first output voltage.
