Best Answer

Yes. If the power supply is of a low wattage and has too many pieces of hardware connected to it, it can. Try buying a power supply with a wattage over 300.

One thing to check before replacing the power supply is the voltage selector in the back. If you use 120 volt power, then setting the power supply to 240 volts will cause the PC to only get half of the power it needs.

External peripherals with their own power supply will not impact the power supply or current in the computer. Printers and monitors usually get their power from the wall socket, not the computer, and the same goes for external modems that plug into the wall. Keyboards and mice take negligible power.

What effect does a power spike have on a computer?

A power spike - also known as a power surge - could harm a computer if the computer's power supply has a low joule (unit of energy) rating. A power spike, a sudden increase in energy, can overwhelm a computer's power supply and cause too much electricity to flow to sensitive chips and processors and destroy them. To safeguard against power spikes a surge protector should be bought. A computer power supply with a high joule resistance rating would work as well.


What are the components of a computer power supply?

Sometimes when people buy a computer power supply unit (PSU), there are several components in the box: a AC power cable to connect the power supply to the wall mains outlet, the power supply itself (PSU) that converts mains power into more useful forms of power, and one or more DC power cables that connect the power supply to the motherboard and other parts of the computer. (On a modular power supply unit, those cables can be detached from the PSU). A computer power supply is in a metal box that is difficult to open, so most people treat a computer power supply (PSU) as a single indivisible component. Inside a computer power supply is a transformer to help convert mains power into more useful forms of power, power diodes and power transistors typically mounted to a heat sink, and other components to help the conversion or to filter the power to meet EMC requirements, and often a fan to blow air on the heat sink to keep the transistors from overheating.


What do you call the component in a computer that converts the wall outlet AC power into the DC power used to run computer DC components?

How does the watt rating of a power supply affect devices you can use in your system?

A low wattage power supply in acomputer can effect your system greatly when adding multiple devices. When you put a to many devices that require more wattage that the power supply can provide, all of the devices will be deprived for power, therefor making you computer slowdown and not very efficient. It can also cause the power supply to burn out quicker. There is no such thing as having a computer's power supply with too much wattage. The computer will only use what it needs. The larger the power supply the more devices you can operate on it with maximum output.
