What should you do to enable your personal computer to work on 230 V AC in the UK?

To enable your personal computer to work on 230 V AC in the UK, toggling the voltage switch on the power supply is the correct approach, provided that the power supply unit is designed with a switch for selecting between different voltage inputs. Many power supply units (PSUs) include a voltage selector switch that allows users to adjust the PSU for use in regions with different standard voltages, such as 110 V in the US and 230 V in the UK.

By toggling this switch to the appropriate setting, you align the PSU with the local mains electricity supply, thereby ensuring that the computer receives the correct voltage needed for operation. This is a critical step, as using an incorrect voltage can damage the power supply and, subsequently, the computer components.

Other methods, such as replacing the power supply, using a voltage converter, or upgrading the power cable, might seem feasible but do not directly address the specification of the power supply itself. Replacing the power supply could be unnecessary and costly if the existing one is compatible with 230 V AC after adjusting the switch. A voltage converter can also work, yet it adds additional components that may complicate the setup and are not typically required when a standard power supply allows for switching. Lastly,
