Answer:

Power supply

Explanation:

A computer's power supply converts alternating current (AC) from the wall outlet to direct current (DC) used by the computer's internal components.

A voltage regulator is an electronic device that supplies the appropriate voltage to a processor. It does not convert the power input from one form to another; it only ensures that the voltage remains at the appropriate level for the device. A surge protector protects a system from power spikes. A UPS (uninterruptible power supply) provides backup AC power using a reserve battery.
