Computer system, expansion component, auxiliary supply component and use thereof

A computer system comprising:

• a power supply unit that provides operating energy for the computer system;
• a system board connected to the power supply unit and having a multitude of expansion connections for connection of a corresponding multitude of expansion components, wherein each expansion component is assigned a fixed power budget to supply an associated expansion component;
• a first expansion component connected to a first expansion connection of the system board;
• and
• at least one auxiliary supply component arranged in a region of a second expansion connection of the system board, wherein the auxiliary supply component electrically connects to the first expansion component and delivers at least part of the power budget assigned to the second expansion connection to the first expansion component.

An expansion component for connection to an expansion connection of a system board of a computer system, wherein the expansion connection is assigned a fixed power budget to supply the expansion component, comprising:

• a first plug connector for connection of the expansion component to the expansion connection;
• a second plug connector to supply an operating energy independent from the power budget of the expansion connection;
• at least one third plug connector to supply an additional component or an external peripheral device with an operating energy;
• and
• a power control electrically connected to the first plug connector, the second plug connector and the at least one third plug connector, the power control adapted to limit the power taken-up via the first plug connector to the fixed power budget and to take-up from the second plug-connector at least part of an operating energy exceeding the fixed power budget and taken up by the expansion component and/or delivered via the at least third plug connector.
