One of the most common components in a computer that creates problems is the power supply. As a result, you should be familiar with the signs and solutions to this type of PSU failure on your computer.
Furthermore, because of the power issues, it may harm other components or cause the device to not turn on.
With this lesson, you’ll learn how to spot power supply issues and determine when it’s time to retire your old PSU and replace it with a new one.
Remember that some problems with your power supply may cause it to not shut down, which could lead to it giving aberrant voltages to other components, causing board or other damage.
Symptoms of a failing power supply
The signs of a failing power source might be numerous. It is not a binary component that works or does not operate; it can work partially or in an irregular manner, concealing the fact that there is an apparent supply.
Unexpected shutdowns or restarts
One of the most common signs is that the computer shuts down or restarts without warning, even though there is no power outage in your region. This symptom isn’t usually caused by the power supply; it could be caused by a motherboard or CPU problem.
If the problem is with the power supply, it is because it is incapable of continually giving the required power or voltage, or there may be some overvoltage, problems with the protective system, contacts, or other factors.
BSoD (Basic System of Design) (blue screen)
It’s not always a sign of a poor power supply; it could also be another hardware issue, such as memory or operating system issues.
They can also arise if the power supply is defective. Examine the code or error message that shows on the BSoD (Blue Screen of Death) and search the network for information to rule out RAM, GPU, and other issues.
If it happens every time you start up a demanding video game or piece of software, it could be a problem with your power supply, which isn’t producing enough power when greater performance is required.
PSU fan problems
It could also be a problem with the power supply if the power supply fan stops running or makes unusual noises. It could be that it has reached the end of its usable life,
that the fan is not receiving electricity, that the fan is malfunctioning, that it is dirty (clean it), or that it is rubbing against something.
If you’re going to disassemble the PSU to inspect it, remember to do so with the power off and wait at least 5 minutes before touching any of its components, as some capacitors can store enough electricity to shock you even after being switched off…
Smell of burning or smoke
One of the most evident signs of a failing power supply is this. You may even hear a tiny explosion and smell burning as the computer shuts down unexpectedly.
This is normally caused by an exploding capacitor in the power supply, so you’ll either have to repair the capacitor (which can be difficult if you don’t have the tools) or replace the power supply.
If you open the source to make sure it’s a condenser, you’ll very certainly notice a swollen condenser, rust or dried acid residues, or possibly a charred black area
Why does the power supply fail?
For different reasons, the power supply frequently fails. Knowing them can help you diagnose problems associated to it and even prevent some of them from happening in the first place:
power supplies typically last several years, with some having a 10-year warranty. However, this does not mean they will not break before then, or that you will have a lower-quality typeface that will deteriorate over time.
Overloaded source –
Some people have a source with a capacity of X watts and plug in more items than they can handle or are capable of, for example, utilising splitters for molex connectors. This will overburden the source, shortening its lifespan.
If the electrical supply signal in your area is not particularly steady, with frequent blackouts, surges, or spikes, for example, the PSU will deteriorate.
Although some sources have active and passive protection measures, they are not always successful.
Its transformer and other components operate at high voltages, making it rather hot. He has his own fan because of this.
If your fountain is operating at an extremely high temperature, or if the air intake is clogged, the fan is dusty or failing, it’s possible that a component has perished prematurely and burned out.
Is it possible to extend the life of my power supply?
There is no perfect formula for avoiding difficulties, and even if you have one of the best power supplies on the market and treat it with care, it will eventually fail. However, the following are some suggestions:
Adequate power :
imagine that you mount a configuration with a consumption of 750w. I would suggest using an 800w source to make it more comfortable to use.
If you push it to its limits, you risk exacerbating the difficulties. You can use an online calculator to figure out how to choose the proper power if you like.
Rare or cheap brand name fonts:
I don’t recommend buying rare or cheap brand name fonts. They frequently lack active or passive protective mechanisms, in addition to being of lower quality.
This could shorten their lifespan while also causing damage to other components such as the motherboard and drives.
Keeping your fan in good working order might help it last longer. Lint and dust build up on it, making it harder to spin and limiting the amount of fresh air flow. This will cause it to overheat more than it should, resulting in component failure.
