The power cord plugs into the end of the connector that plugs into the PC.

Check your power supply cables Your power supply cables may not be fully secured. Let's unplug and reconnect your power supply
  1. Disconnect the power cord from the back of your console. Unplug the power cord from the wall outlet and the power supply unit.
    Reconnect the power cord to the console. Then plug the power cord back into the wall outlet and the power supply unit
  2. Make sure that all three connections are firmly secured.
  3. Turn your console back on.

Check the light on the power supply. If this solution worked, your power supply light will be green

Hook up to the CPU


Two cables are needed, Power and Data signal (VGA). Most monitors take the same type of power cord as computer power supplies. (Some computers will allow you to plug in a slightly modified cable that will power the monitor off the computer's power supply. This cord has similar ends on both sides (with the prongs inside a rubber housing). The only issue with this is it makes the power supply work harder and thus can fail sooner.) Most computer supply shops (online and brick-and-mortar) will have the power cables, if you don't have extra cables hanging around.

I hope this helps.

Perform the following steps, in order, until power is restored or it is determined that there is a hardware failure:

1.Disconnect everything from the computer, including the power cord.
2.With the power cord disconnected , press the power button on the front of the computer for five seconds. Plug in the power cord and test to see if the computer can turn on. If not, continue using these steps.
NOTE: If the power supply fan makes an inconsistent grinding sound or stops and starts erratically, replace the power supply

3. With the power cord removed, flip the red voltage selector switch to the opposite position. Wait about five seconds, and then switch the red voltage selector switch back to its original location. Ensure that the voltage selector switch is on the correct setting, 115V for North America.
Performing this step ensures that the voltage switch is engaged and set correctly for your country/region.

4. Plug in the power cord and test to see if the computer can turn on. If not, continue using these steps.
5. Plug a lamp into the same outlet to see if the wall outlet has power. Try the computer in a different outlet in order to eliminate the outlet as a possible source of the issue. Test both to see if the wall outlets have power.
6. Remove all extension cords, power strips, surge protectors and any converters that remove ground. Plug the power cable directly to the wall outlet. Test for power. If this fixes the issue, find the device that is causing the issue and do not use it.
NOTE: If you find the device that was causing the problem was a surge protector, resetting a breaker or fuse on the surge protector may fix the issue.
8. Remove all attached devices except for keyboard, mouse, and monitor.
9. Remove any internal component that was recently added, such as video card, memory, CD, DVD, and hard drives. An added device may take more power than the power supply is rated for. If the problem goes away when the component is removed, the only option is to upgrade the power supply to power supply with a higher wattage rating.
10. Check the power switch:
a. With the power cord disconnected, press the power button on the front of the PC. The button should release easily and not stick in the socket.
  • If the button sticks, it should be replaced or serviced.
  • If the power button does not stick and appears to be functioning, continue using these steps.
11. With the power cord disconnected, remove the case or side panel.
  • Follow the wires from the power button on the front of the computer to their connection on the motherboard.
  • Look at the power switch cables connected to the motherboard. If the cable has become disconnected, connect the power switch cable connector to the connector on the motherboard.
  • Replace the side panel, plug in the power cord and test to see if the computer can turn on. If not, continue using these steps.
12. Find the defective part:
  • With the power cord disconnected, remove the case or side panel.
  • Disconnect all power cable connectors from their connectors on the motherboard and from the back of internal devices (the back of drives). Make sure to label or remember where each cable connects for future reference.
  • Replace the side panel, plug in the power cord, and examine the light on the back of the power supply:

13. If the LED is on solid and is not flashing, the power supply is probably good and the problem is most likely caused by a defective component (processor, memory, PCI card) or a defective motherboard. Have the computer serviced, or remove the components and replace them, one at a time, to find and replace the defective component.

14. If the LED is still flashing (it should not flash with all connectors removed), plug the power cable into a different power outlet that is known to be good. If the LED still flashes, the power supply should be replaced.

15. If the LED light is now off, plug the power cable into a different power outlet that is known to be good. If the LED stays off, the power supply should be replaced.

NOTE: If an electrical storm or power surge has recently occurred, then it is more likely that the power supply, the modem, or motherboard is damaged and requires replacement.

Well my power suply fried and i got another one but when i turn it on the moniter says its disconnected i here the hard drives and all the fans r running what do i do


did you plug everything back to the new power supply?? is your monitor data cable connected properly??
please check everything is properly seated (don't assume... spend 5 minutes checking everything again) and make sure you GROUND YOURSELF by at least touching the power supply first before touching any component inside your pc.. don't forget to unplug the power cord from the power outlet!

some motherboard may have not only 1 but to power connectors, check your motherboard manual to ensure you're plugging everything that you need to plug (no more or less.. just about everything that needs to be plugged.. depending your motherboard and cpu power requirements.

check your memory is seated properly.

is your power supply of the same wattage as the previous one or larger? (if it's larger that's fine.. you gotta make sure you do have sufficient power)

Power cords and mice you can pickup at almost any computer supply place. The power cord should be no more than $5, and basic optical mouse can be bought for $10 -15. I have one of these machines and I think they are 2004 - 2005 vintage.

I think it would get power through the Moniter so I don't think you need a power cord for the CPU. Hope this helped =)

Have tried wall-mart


Well now if you go asking shop folk for this -they wont use their imagination, just in case they get it wrong and you sue. Just be sure that the voltage you need is - what it is - 12V did you say Then go the the electrical isles small items and you will see usually in a bubble pack on the rack a power supply- with a strip of various connectors. The power supply will have a slider switch to select vorltages from 1.5-3-4.5-6-7.5-9-12 volts. These will also have a coloured patch. The connectors are also coloured on the tip. Pick the connector colour that matched the voltage colour- plug in into the cord and lug it into the monitor . And it does not work Huh! Then unplug the connector from the cord and turn it around plug it in- then it it will work.
