The usual voltages produced by the power supply in a standard personal computer system are 5 volts and 12 volts. For more information see the Related Link shown below.
+5v necessary for microprocessor 8085.
+5v supply is alone needed for Intel 8085 Microprocessor
Put a seprate transformer. It will solve this issue
The power supply in a PC is a complex device using switch mode circuitry and transformers to generate +and- 12v, for modems and communications ports. +and-5volts for the… logic circuitry,3volts for the processor. All these supplies are generated and electronically regulated. It is such a waste when they are thrown a way still working. They are mini masterpieces of electronic engineering and are capable of starting a car!
The 8085 and 8086/8088 operate on 5 volts.
At Least, 115 volts. Which is standard from a wall outlet. If should not matter how many volts your computer needs, but the watts does. For most computers they need anywhere f…rom 100-800 watts.
The maximum supply voltage per the data sheet is 5.25 volts. This is a common max for TTL type IC's.
The term, 'nominal', simply means 'named'. For example, the nominal supply voltage for a residence in the UK is 230 V. But this doesn't mean that the actual supply voltage is …230 V, because the supply voltage is allowed to vary by -6% and +10% of the nominal voltage. In other words, the actual voltage could be anywhere within the range of 216.2 V to 253 V. In fact, during periods of heavy load, the actual voltage would tend towards the lower end of this range, whereas during periods of higher load, the actual voltage would vary towards the upper end.
The two outside contacts (of four contacts) are connected to the power supply in the computer.
Depending on the power supply, +12, -12, +5, - 5 and ground. Some also use 3.3.
It convert 220v or 115 to -12v and +12v by using many components and step down transformer.
In theory, voltage should be the same around the clock. In practice you may get a tad higher voltage at nights, as there's less load on the system. With most people asleep, th…ere aren't as many machines running.
