How Do You Test A Computer Power Supply?
A computer power source converts alternating current (AC) to direct current (DC) and provides a secure ground in case of electrostatic shock. You should test a power supply before plugging it into your computer to ensure that it is operating correctly and doesn’t pose a risk to your computer. Unplug everything before you begin. When manipulating the power supply, it should be in the off position labeled (O) and unplugged. This will prevent potential electrocution. Connect your 3.5-volt fan to one of the cable connectors leading from the power supply. Low-end power supplies in the 300-volt range will typically have at least three connections. The connection will have a female end with room for four pins. Your fan has a male connector with four pins. Connect your power supply to the wall outlet or other AC source. Turn on the power supply on by flipping the switch in the back to the up (I) position. This should turn on the fan. Inspect the fan for normal operation for several minutes. If
