How To Tell If Power Supply Is Bad For Motherboard?

Computers are a set of complex components and functions, and Motherboard is one of the most eminent parts. Whenever users see that the Motherboard is not functioning properly, they may often all be in doubt about whether the power supply is bad or Motherboard. It is important to find the solution, as defects in any of these can majorly affect the functioning of the device. Let’s dive into this article to find out how to tell if the power supply is bad for Motherboard.

How To Tell If Power Supply Is Bad For Motherboard

How to tell if the power supply is bad or the Motherboard?: Signs for Bad Power Supply Unit (PSU)

To define, a PSU is a metal cased box in the CPU which is responsible for providing appropriate power to the Motherboard when the device is turned on. Here are a few indicators that your PSU is faulty:

Is the output not balanced?

The first and the basic indicator of a faulty PSU is the unstable output of power it gives. Remove the connections of the PSU in your device and check the output and inputs with a multimeter. If the output fluctuates reasonably, there may be defects in it. Due to major fluctuations, the Motherboard, too, won’t function properly.

Is your device still staying Off even after turning PSU on?

With minor fluctuations in the output, the efficiency of the device is hampered. But, if you have major fluctuations, the PC will not turn on at all. Therefore, if you see that the device does not turn on at all, it can mostly be the fault of the PSU. Also, there can be other reasons like malfunctioning AVR and power connectors. Thus, this cannot be a solo and reliable indicator of the PSU failure- nonetheless worth considering.

Is there any burning smell coming out of your device?

Power failures or damage in the components often result in a burning smell in the electronic components. This is often evident in PSU most of the time. Accordingly, this fact can be a clear indicator of PSU damage compared to other components. Other relevant indications include additional sounds from fans, sudden power down for computers, and also sparks or fires.

Is your device freezing down suddenly?

Due to variations and sudden surges of the supply, the operation of the PC often gets frozen- making it a sign of PSY failure. But this sign can be equally determining for failure in the hard drive, RAM, and Motherboard as well.

Are you facing Repeated and automatic reboots?

When PSU is not in proper condition, we already discussed that it might lead to fluctuating powers. For this reason, the device may turn off at sudden power failure and restart soon when the power retains its quality. Thus, it may often be a clear indicator of the malfunctioning PSU.

The above factors individually may not give a clear indication. But when they are observed simultaneously, one can make out if the issue is in PSU or not.

How to tell if the power supply is bad or the Motherboard?: Signs for Defective Motherboard

The Motherboard is almost the most important part of the PC. Therefore, if the Motherboard doesn’t work, almost the device gets dull and nonfunctional. Another reason why it is so important is that this board houses almost all the crucial components like drives and RAM. This means all of these get inactive too. With these insights, you can know how to tell if the power supply is bad or if Motherboard.

Are you getting an Endless blue screen?

No matter what minor defects the Motherboard has, it gives out a notification, or this can be discerned as some working defects. But, an endless blue screen has a different story. Almost all the motherboards have a similar meaning of blue screen- STOP Error or “Death screen .”This implies whether there is a crash of the OS or devices. You can have only one option- to restart the device. If you still get the same screen again, there is every chance the Motherboard is defective.

Did you see any indicator on the booting screen?

Commonly called a Power-on self-test, every time the device turns on, Bios tests all the components of the device before loading the OS. In case of any defects in the Motherboard or any other components, it is displayed on the screen itself. Here are a couple of common error signs:

  • There can be blinking lights or beeps
  • Error prompts may appear
  • Check if you are getting any of these, and make sure you are getting closer to your conclusion.

Are you facing power issues?

As depicted in the previous lines, a sudden surge of power can frequently restart the device. It can also damage the Motherboard sometimes. In these cases, the device may not turn on; thus, no power can also be a symbol of motherboard failure.

Can your computer recognize USB and other peripherals?

It can be complicated to diagnose and discern, but it is an important sign of motherboard failure. The extent of the defect can start from recognizing the flash drive connected to the device. And then other components like mouse, cards, and speakers may also stop responding. While these can initially be perceived as a failure in individual hardware components, drastic failures in multiple aspects can indicate an issue with the Motherboard.

So, how to tell if the power supply is bad or the Motherboard?

It may be difficult for a person to determine how to tell if the power supply is bad or Motherboard. But a reliable conclusion can be taken from analyzing a few signs with the device. Since there are some common attributes in PSUand motherboard failure, discerning the actual area of defect can be initially daunting. But, Putting together the results of the above signs and analyzing them can help you get down to a reliable conclusion, as PSU or Motherboard is defective. Check out the above insights and effortlessly determine where the issue actually exists.
