Is it possible to Test a computer’s CPU without the motherboard?

Because the problem could be caused by either the power supply unit (PSU) or the motherboard, determining what is wrong with a computer’s power supply can be challenging.

It is much simpler to pinpoint the source of the issue when each component is put through its own set of tests.

You can get past the fact that power supply units (PSUs) are only meant to function properly when they are linked to a motherboard by employing a piece of wire that is only a few inches long.

With the help of this workaround, also known as the “paper clip test,” it is possible to determine whether or not the power supply unit (PSU) is receiving electricity without making use of the motherboard.

  • Remove the power supply unit (PSU) from the motherboard and the wall outlet, and then pull it out of the computer case. The PSU should be removed in one piece. The paper clip test basically involves sending electricity via the power supply unit (PSU), and if the wire that is being tested touches another component of the computer while it is being checked, it may result in a short that destroys that component. To prevent the power supply unit (PSU) from being harmed by other components of your computer, you should relocate it.
  • On the connector for the power supply unit for the motherboard, determine which wires are black and which are green. ATX power supply can have either 20 or 24 pin connectors, and the wires inside can be any one of several colours. The green cable coming from the power cord is the live feed, while the black wires are for the grounding of the device. There is just one green wire, however there are a lot of black wires that are wrapped around it. There is no such thing as an incorrect or right black wire because all black wires serve as ground wires.
  • Form your wire in such a way that you can test it. Either cut a short piece of insulated wire and remove the insulation from both ends of the wire, or straighten up the paper clip so that it resembles the letter “U.” If you have to use a paperclip, you can protect it from getting damaged by wrapping some electrical tape around the “U” form that it makes.
  • Insert one end of the wire into the green pin connector, then insert the other end of the wire into the black pin connector. While the power supply unit is still disconnected from the wall outlet, all of the power switches located on the power supply unit itself should be set to the “Off” position. Check to see that the wire is hidden in a secure location.
  • Connect the power supply by plugging it in, and set the power switch so that it is in the “On” position. As soon as electricity is supplied to the device, the fan ought to immediately start turning over and over again. During the course of the test, you should connect the device to the wall socket without using a surge protector or any other type of extension cord. It’s possible that your power supply unit is faulty and has to be replaced if you can’t hear the fan inside. Before you begin cutting the wire, make sure the power supply unit is turned off and that it is unplugged from the wall.
