System Requirements
Power Supplies for 486 Computers
A clean steady power source is necessary to get reliable perfor-
mance from the system. With the high clock speeds of the CPU
(running at
20MH z or above) the quality of the power supply
becomes even more important. Most p o w e r supplies o n the market
meet the standards required by the CPU, however some have been found
to be out of specification. To be certain of the highest performance
by your system, be sure your power supply provicies a voltage
range of 5.25 volts maximum to 4.95 volts minimum.
In areas with noisy power transmission, we suggest the use of a
line noise filter between the power and the computer.
