A power converter for a computer device having a processing unit and a memory device is suggested. The power converter is connectable to the computer device by a coupling circuitry, wherein the computer device requires an actual input voltage. The power converter comprises a voltage regulator, a measuring entity, and a determining entity. The voltage regulator is configured to control an actual output voltage for the coupling circuitry based on a determined reference output voltage. The measuring entity is configured to measure an actual output current of the voltage regulator output to the coupling circuitry. The determining entity is configured to determine the determined reference output voltage such that the determined reference output voltage equals a sum of the actual input voltage of the computer device and the product of the measured actual output current and a resistance of the coupling circuitry.
