All about Power Supplies
In a personal computer (PC), the power supply is the metal box usually found in a corner of the case. The
power supply is visible from the back of many systems because it contains the power-cord receptacle and
the cooling fan.
FACTOIDS ON POWER SUPPLIES
A 400-watt switching power supply will not necessarily use more power than a 250-watt supply. A larger
supply may be needed if you use every available slot on the motherboard or every available drive bay in
the personal computer case. It is not a good idea to have a 250-watt supply if you have 250 watts total in
devices, since the supply should not be loaded to 100 percent of its capacity.
According to PC Power & Cooling, Inc., some power consumption values (in watts) for common items in a
personal computer are:

Power supplies, often referred to as "switching power supplies", use switcher technology to convert the
AC input to lower DC voltages. The typical voltages supplied are:
3.3 volts
5 volts
12 volts
The 3.3- and 5-volts are typically used by digital circuits, while the 12-volt is used to run motors in disk
drives and fans. The main specification of a power supply is in watts. A watt is the product of the voltage
in volts and the current in amperes or amps.
If you have been around PCs for many years, you probably remember that the original PCs had large red
toggle switches that had a good bit of heft to them. When you turned the PC on or off, you knew you were
doing it. These switches actually controlled the flow of 120 volt power to the power supply.
