A bad Power Supply could damage many components inside your PC system, but people have many questions about whether a bad Power Supply damages the CPU or not.
I did complete research about bad PSU’s impact on the CPU, and here in this article, I will explain whether PSU damage the CPU or not. So, keep reading this article till the end.
Bad PSU Can Damage CPU
Yes! A Bad PSU can damage various hardware components in our PC system, including the CPU. It can destroy everything in our PC system, but the thing is, it won’t damage your CPU instantly. But if you use a bad Power Supply for a long time, then it could slowly damage your system’s components, including your CPU.
How Can A Bad PSU Damage Your CPU?
If you are using a cheap PSU, a Bad PSU, or an old PSU, and if the PSU has some kind of flaws, then it could cause several PC problems.
This Power Supply situation could cause all sorts of things to our computers. If your PSU starts to fail, the most common thing that could happen is that it will deliver the wrong amount of electricity.
Moreover, due to this bad PSU condition, the voltages and amps might be dropped or rise beyond the safe limits, which can cause the PSU to overheat and also cause the other PC parts to fail.
CPUs & GPUs are the most sensitive parts of our PC system, and if the PSU gets overheated, then it would eventually fail the sensitive components like the CPU.
How To Know If PSU is Damaging CPU?
It is difficult to know whether your Power Supply is causing damage to your CPU or is it something else that is causing damage.
Here, we will explore all the symptoms that will tell you that your PSU is causing damage to your CPU. So, let’s take a look-
If you are facing computer freezing issues, computer booting issues, the computer automatically turning off issues, Beep alerts, or BSoD (Blue Screen Of Death) issues, then these are some of the symptoms that your CPU is degrading. Know How A PSU Can Cause screen issues?
But, these indications won’t tell you whether your PSU is causing this, or is it something else? So, how Do you understand this?
Generally, the BSOD(Blue Screen Of Death) issue usually indicates that your Power Supply is unable to handle the load being put on it by your system. So, if you are facing such issues, then you should check your PSU first.
If you notice your PSU is causing the issue, keep your computer turned off until you get a better Power Supply. Moreover, experts also recommend using a PSU that has twice the maximum wattage of your PC’s requirement. For instance, if your PC requires 250W, then use at least 500W, and for the most part, the 500W PSU is enough.
Overall, it has to be said that if you have a cheap PSU or old PSU and are getting BSOD issues, you should check your Power Supply first.
RememberThe BSOD (Blue Screen) issues don’t always appear due to bad Power Supply; these issues can arise due to the damage to other PC components. So, before replacing the PSU, you should always check whether your PSU is causing this or if it is something else.
Other Reasons That Could Damage The CPU
Not only the bad Power Supply but various other reasons could cause damage to the CPU, and here we are going to explore all the other factors that could cause the CPU to fail. So, let’s explore the reasons-
Usually, the CPU is damaged when its capacitors go wrong, and there are several reasons why these capacitors go bad. So, let’s see the causes-
One of the major causes behind why PC components get damaged is the heating. The overheating can cause CPU failure, and if the CPU cooler you are using is not sufficient enough to cool your CPU, it will fail. Sometimes the increasing room temperature could also cause the CPU failing issues.
Over time every electrical component loses its frequency, and the same thing applies to the CPU. If your PC is more than five years old, its components might not function efficiently, which could cause the CPU to fail.
In Computing overclocking is the practice of increasing the clock rate of a computer to exceed that certified by the manufacturer.
Many gamers want to overclock their CPU & GPU for better performance but to overclock your system, you need at least eight core CPUs & better cooling. But, if your CPU is not that strong or cooling is not good, then due to overclocking, your CPU gets damaged.
Power Surging is a situation where you will see spikes in your electrical system current. Most of the modern PSUs come with Power Surge protection. Read Which PSUs have Surge Protections?
Power Surging can impact your PC negatively, by damaging the sensitive parts of the pc systems like the CPU if the Power Supply you are using doesn’t have any surge protection.
These are some of the reasons that could also damage your CPU. So, if you notice that your Power Supply is degrading, you should check all of these factors besides the Power Supply.
Can An Underpowered PSU Damage The CPU?
An underpowered PSU can negatively impact your CPU in various ways, but it doesn’t damage your CPU immediately; but over time, if your CPU doesn’t get the power from the Power Supply, it will get damaged.
On average, an Intel i7 or i5 CPU takes 65W to 91W of power from the PSU, and if your PSU cannot supply that required power, then it would not work sufficiently.
Can A Bad PSU Cause A CPU To Overheat?
If your PSU has some faults, then it will push out unstable voltage, and due to this issue, it would cause the CPU to overheat. Not only PSU, there are other reasons too that could also cause the CPU overheating issues like bad CPU cooling. Read How A bad PSU Cause A CPU to Overheat?
Many people think that PSU wattage impacts the CPU temperature, but the PSU wattage has nothing to do with CPU temperature. To know more, read this article.
At last, I want to summarize everything for you that an inadequate Power Supply could damage your CPU, but other reasons could also damage your CPU. So, before replacing the Power Supply, you should check all the reasons to identify the actual cause.
I hope this article is helpful for you and if you want to know more about the Power Supply, Motherboards, CPUs, and other PC components, keep following this blog regularly.
