Power Supplies
The one component that is
absolutely vital to the operation
of a computer
Power Supplies
Power Supplies
Often referred to as "switching
power supplies", because they use
switcher technology to convert the
AC input to lower DC voltages. The
typical voltages supplied are:
3.3 volts 5 volts 12 volts
Power Supplies
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.
Power Supplies
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

may be needed if you use every
available slot on the motherboard or
every available drive bay in the
personal computer case.
