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 other people do inside their computers, like extra DVD drives and lights and things.

Take out the PSU (Power Supply Unit) It's the largest box inside your computer with a fan on it. Without power = no computer.

Check the power supply, if its good then your bios might be at fault.
How much kilowatts does it take to run a personal computer?
Most computer use anything from 300 watts to 1200 watts.
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.
If your PC does not start up when you push the power switch what should you look for to resolve the issue?
First, check to make sure that the computer is plugged in.If it isn't, then plug it in.If it is and you still have issues, you might have a power supply problem. In which case, you need to buy a new power supply and install it, or take your computer to a computer store and have them fix it.A power supply, when referring to computers, is that little fan/box thing that you plug the cord from the wall to the computer.
When adding hardware to a computer how do you know at some point if you are in danger of not having the proper power supply for the add ons?
If your computer mysteriously restarts itself with no prompts, this is a major sign that your power supply is not providing enough power to your computer. You cannot harm your hardware by not offering enough power, so don't be worried about that. Things that spin eat up the most power, such as fans, CD-roms and hard drives. Addings lots of PCI cards don't take much power. I have 2 hard drives, 2 DVD drives, an intake fan and a hard drive cooler on my 350W power supply and it runs fine.
Can you get info off computer with failed power supply?
Yes, as long as the rest of the computer is still intact (eg. motherboard, hard drive etc.) You can either: Get a new power supply for the computer and everything should work as normal (power up and everything) Take out the hard drive and put it into another computer to recover the data (there are many ways of doing this, try googling it - that should help.

How can you troubleshoot your computer if it turns on and then turns off?
I've had this same problem myself. It's really easy to fix if you have an old computer or can get old parts. This will only work if you have a desktop pc. The problem may be in your power supply. It's the box inside your computer that the power cord goes into. I'm not promising that this is going to work, but it did for my. Just unscrew the power supply from you computer, unplug the cords from the motherboard and take out the plugs in your hard drive and cd-rom. Then screw the new power supply in and hook it up the same way your other was. That should fix the problem. I don't recommend buying a new power supply. An olld one does just fine. They may not be as compact, but it will do the trick.
The fan in a 250-watt power supply is malfunctioning. what action should you take?
