What supply voltage does a computer need?
0.8-1.2V Depends on manufacturer and technology options.
EMachines are notorious for coming with under-powered power supplies, and several fires have been known to occur due to overheating and overloading of the PSU. In general, as… a professional repair technician, I would say ALL eMachines need a new PSU on purchase. However symptoms of a direct PSU failure are: Failure to turn on (No fans, no lights, no noise) Crashing or instability, especially during heavy use Strange noises (high pitched whines, 'buzzing') Excessive heat from the PSU (exceeding 140 degrees F) Upgrading ANY component to a higher-powered component, or adding any new high-draw peripherals (even external hard drives that are not self-powered) can cause an immediate overload of a PSU. Troubleshooting a PSU involves removing all non-essential components (wireless cards, NIC cards, extra memory, hard drives, video cards [if onboard is present and useable], extra fans or cooling [NOT the CPU fan!!!], external components, etc. If it suddenly begins working with objects removed, it is likely a shortage of power. Keep in mind some other malfunctions can mimic PSU problems, such as failing motherboards, overheating, and bad RAM.
The nominal mains voltage in the UK is 230VAC, 50 Hz.
In the U.S.A., 110VAC is the usual household receptacle voltage where lamps, TV's etc are connected and the computer, printer & related devices are also connected. Other count…ries may have different operating voltages required for computers.
Conceivably, if you were right at the point of maxing out your old power supply and you gained additional speed by having more ram, you might increase the power demand e…ver-so-slightly by allowing the computer to function faster. Possible but not likely. While you have the case open, it wouldn't hurt to blow dust out of the power supply. Overheating because of dust buildup is as hard on it as anything.
The supply voltage of the 8085 is 5 volts.
A good computer lab power supply has a battery backup that gives you a few minutes to save your stuff when the power goes out.
This is from HP's website: DescriptionIf you are using a voltage adapter [I think they mean voltage "converter"] to work outside the US, you may have difficulties… charging the battery and other power anomalies. SolutionHP and Compaq power adapters are setup for World Wide voltage and frequency specs. They do not require any power conversion. Plugging our adapters into any sort of power converter may cause the adapter to malfunction.The only adapter needed to use our AC adapter in a foreign country is a plug adapter to make the plug fit the wall receptacle.
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!
It convert 220v or 115 to -12v and +12v by using many components and step down transformer.
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 maximum supply voltage per the data sheet is 5.25 volts. This is a common max for TTL type IC's.
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.
What should be the setting for a dual voltage selector switch on a power supply when using the computer in the us?
There is no set amount of power every computer built will need because different parts consume different amounts of electricity. Some people have more components than ot…her people do inside their computers, like extra DVD drives and lights and things.
A: Depends on the circuitry involved an op amp normally has a 90 Db rejection from variation, Logic gates however are more sensitive to power supply variation for the simple p…oint that triggering points changes which translate in false triggering and the circuits miss behaving

The 110VAC to 125VAC range (not the 220VAC to 250VAC range).
