How is the power supply of a computer measured?

Power supplies are rated at the maximum wattage they can put out. Of course, a computers requirements vary depending on what the computer is doing, so a computer power supply should be of the same, or greater, wattage requirement of the computer when under it's greatest load.


How many cables are supplied by power supply?

Depends on what wattage it is, and the manufacture. You can use adapters types of wire connections, and sometimes you can get splitters.


Are power supplies interchangeable?

Yes. A power supply is most definitely replaceable. When replacing a power supply, make sure you know how much watts your computer requires to run. Be sure you are not buying too little "wattage" of a PSU.


Can the power supply cause the computer to be difficult to turn on?

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.


How many watts are the power supply?

Well it all depends on how high-end your computer is. If it is a rather basic model there are probably between 450 and 500 watts, but if you have a higher-end computer, it will probably have between 600 and 850 watts. This way the higher the ammount of watts your computer has the more power it will have to run the hardware of your computer.

Can i have too much wattage for a PC?

Yes, having too much wattage for a PC power supply can be inefficient and may lead to higher costs upfront. It's important to calculate the power requirements of your components and choose a power supply with a wattage rating that comfortably supports them without excess. Having significantly more wattage than needed can also decrease the power supply's efficiency and waste energy.


How do you determine the power wattage capacity needed by a power supply?

Hi there guys, this is the answer you all looking 4.Add up all wattage requirements for all devices that will use the power supply and then add an additional 30%.


What is the recommended wattage capacity for a power supply for?

If you have a 500 watt power supply and you want to put in a new video card. On the video card's box it will tell you how much power it needs. If it requires less power then you don't need to worry. If it says it requires more, you'll need a bigger power supply with large wattage otherwise you'll kill your computer.


What is the voltage drop across each lamp?

To answer this question a supply voltage must be stated. Also the wattage of the lamps is needed.


What is the pricing strategy that is needed when you are trying to maximize revenue when capacity is a factor?

increase price, decrease supply


How do you calculate motor wattage from its resistance?

All you can do is get in the ballpark knowing resistance of windings and the supply voltage. Current = Voltage divided by resistance. Wattage = voltage x current x power factor. For a motor the power factor is between zero and sone number less than one, with one being just a resistive load. So if you calculate the current and use a PF = 1 you can get worse case wattage.


When computing wattage when to include power factor and square root of three?

In its simplest form the equation to calculate the wattage of an electrical appliance is: Watts = voltage x current. If the appliance is in a AC supply use the Route mean square voltage (the stated AC voltage).


How many voltz and watts can you use to go up to 800watts?

To calculate the voltage needed to achieve 800 watts, you can use the formula: Wattage = Voltage x Amperage. If we assume a standard power supply with an amperage of 10A, then the voltage required would be 80V (800W = 80V x 10A). Make sure your power supply can handle this output to safely achieve 800 watts.


What is the recommended well pump wattage for efficient water supply in a residential setting?

The recommended well pump wattage for efficient water supply in a residential setting is typically between 1,000 to 2,000 watts.


What pieces of information are needed before selecting a power supply?

The main piece of information needed is the load wattage or amperage that will be connected to the power supply. Once this is known the power supply of a greater size that the load should be chosen. Also with this information the size of the wires can be calculated from the power supply to the load. Too small a wire will create a voltage drop at the load end of the circuit. This will cause under performance of the load.


Can i replace a 350 watt power supply with 300 watt?

It is not recommended to replace a 350 watt power supply with a 300 watt power supply, as the lower wattage may not provide enough power for your components. It's best to match or exceed the wattage of the original power supply to ensure proper functionality of your system.
