When purchasing a power supply, you need to consider the power output of the components you have (or plan to put inside) your PC. Your CPU, graphics card and hard drives will be the main power users, so get a power supply that matches the overall power output of your components.
For example, my PC has an Intel i7 3770K and a GTX680 (overclocked) which are fairly higher-end components, and the 650 watt power supply powers those and my 2 hard-drives adequately. If you have a very new processor and graphics card (intel 4xxx series or geforce 7 series for example), then it would probably be good to go 700 or above.
The statement "the power supply must be toasted" is a rather idiomatic way of saying, the power supply must have been destroyed by excess current.
There are a great many factors that must be considered when buying the perfect pearl such as color. Other factors include size and shape.
You can measure the current and power of a 'power supply', using an ammeter and a wattmeter. With the power supply connected to its load, the ammeter must be connected in series with the power supply's input. The wattmeter's current coil must also be connected in series with the power supply's input, and its voltage coil must be connected in parallel with the supply, taking the instrument's polarity markings into account.
a power supply must deliver xxx watts to a load the transformer must match the load capabilities plus its own loss
Case: Your motherboard must be able to fit in your case and must support your motherboard size (correctly placed standoffs). Power Supply: You can't have a shortage of power or else your power supply will get overloaded and "die", or even possibly explode for that matter.
No FireWire does not need a separate power supply to operate. FireWire is used to connect peripheral devices to a computer.
is an embedded circuit or stand alone unit the function of which is to supply a stable voltage to a circuit or device that must be operated within certain power supply limits .

The equipments power requirements, and the mains voltage. The output of the power supply must be able to deliver the correct voltage to the equipment, at the appropriate wattage. Additionally, it should be capable of operating on the supplied mains voltage and wattage.
Personnel; equipment condition; equipment supply; and training must be considered when assessing a UTC in ART.
The power supplied by a three-phase supply, or any supply come to that, is determined by the LOAD, and not by the supply. So you must look at the data provided on the equipment's nameplate to find out what its power rating is.
