Description
A power supply rated at 40A and 12V provides a maximum current (amperage) output of 40 amperes at a constant voltage of 12 volts. In electrical terms, this means it can deliver up to 480 watts of power (12 volts x 40 amperes = 480 watts). These power supplies are often used in a range of applications where a stable 12V power source with a moderate to high current capacity is needed, such as for some gaming computers, LED lighting systems, hobbyist electronics, and various industrial and automotive applications.
