| power supply tester | Used to measure the output of each connector coming from the power supply tester. |
| power supply | Also known as a Power supply unit (PSU). A box inside a computer case that supplies power to the motherboard and other installed devices. |
| radio frequency interference | EMI in the Radio frequency range. |
| rectifier | An electrical device that converts AC to DC. A PC power supply contains a Rectifier. |
| resistor | An electronic device that resists or opposes the flow of electricity. A Resistor can be used to reduce the amount of electricity being supplied to an electronic component. |
| riser card | A card that plugs into a motherboard and allows for expansion Cards to be mounted parallel to the motherboard. Expansion cards are plugged into slots on the riser card. |
| soft power | Another term for a Soft switch. |
| soft switch | A feature on an ATX or BTX system that allows an OS to power down the system and allows for activity such as a keystroke or network activity to power up the system. Also called Soft switch. |
| spikes | Temporary surges in voltage, which can damage electrical components. Also called Spikes. |
| static electricity | An electrical charge at rest. Also known as Electrostatic discharge (ESD) |
| surge protector or surge suppressor | A device or power strip designed to protect electronic equipment from power Surges and spikes. |
| tower case | The largest type of personal computer case. Tower cases stand vertically and can be as high as two feet tall. They have more drive bays and are a good choice for computer users who anticipate making significant upgrades. |
| transformer | A device that changes the ratio of current to voltage. A computer power supply is basically a Transformer and a rectifier. |
| transistor | An electronic Transistor device that can regulate electricity and act as a logical gate or switch for an electrical signal. |
| uninterrupted power supply | A device designed to provide a backup power Supply during a Power failure. Basically, a UPS is a battery backup system with an ultra-fast sensing device. |
| volt | A measure of potential difference in an electrical circuit. A computer ATX power supply usually provides five separate Volt: +12 V, -12 V, +5 V, -5 V, and +3.3 V. |
| voltage selector switch | Voltage Selector switch on the back. Often, the voltage selector switch on the power supply can be set to 230 V or 115 V. When in the United States, set the switch to 115 V. |
| watt | The unit used to measure power. A typical computer may use a power supply that provides 200 Watt. |
