    摘要: Apparatus forming a computer system or such-like is disclosed that includes a central processing unit (CPU) and a power supply unit. The CPU provides a digital voltage ID (VID) signal output indicative of the power supply voltage that it desires to receive. The power supply unit has a control input for receiving a digital VID signal from the CPU. The power output from the unit is then provided to the CPU at a voltage level in accordance with the received digital VID signal. A VID offset generator is interposed between the CPU and the power supply unit. This receives the digital VID signal from the CPU, and modifies it by applying a positive or negative offset. The modified digital VID signal is then passed to the power supply unit, which supplies a voltage to the CPU as per the modified VID signal, rather than the VID signal originally output by the CPU.
