Will a Low Wattage PSU Harm My Computer?
Whenever we talk about computer hardware, the one component that plays a crucial role in the proper functioning of a computer is the power supply unit (PSU). It is the power supply unit that provides the necessary power to all the components of the computer like the CPU, GPU, motherboard, RAM, and others. On the same note, the wattage of your PSU plays an imperative role in determining the performance of your computer. In this blog, we will be discussing everything that you need to know about the wattage of a PSU and its impact on the computer’s functioning.
What is Wattage?
Wattage is the measure of power that any device is capable of drawing. It depicts the amount of power that is being consumed by an electronic device. Wattage comes in different ratings and it is usually marked on the device. For instance, a light bulb that requires 40 watts of power will have the rating of 40W marked on it.
What is a PSU?
A power supply unit is an electronic device that provides the necessary power to the components of a computer. It is responsible for regulating the flow of the electric current from the wall outlet and transforms it into an appropriate power supply for the computer. The PSU usually converts the AC power supply from the wall outlet into a DC power supply that is required by the computer. The PSU has different cables and connectors that provide power to the components of the computer like the CPU, GPU, motherboard, and RAM.
What Wattage is Required by a Computer?
The wattage required by a computer depends on the components that it has. The PSU has to be powerful enough to provide the necessary power to all the components of a computer. As the components like the CPU, GPU, and others consume different amounts of power, the wattage of the PSU required for a computer will vary. Typically, the wattage of a PSU for a gaming computer would range from 500W to 1000W depending on the components.
What Happens if You Use a Low Wattage PSU?
Using a low wattage PSU for your computer can cause a lot of problems. A PSU that is not powerful enough would not be able to provide the necessary power to the components of the computer. This can cause several problems like:
● Overheating of the components – When the PSU is not able to provide the necessary power to the components, the components might start to overheat. Overheating of the components could lead to hardware failures, crashes, or sudden shutdowns.
● Low Performance – A low wattage PSU would not be able to provide the necessary power required by the components of a computer. This can lead to low performance of the computer. The computer might not perform well while playing games or running heavy applications.
● Hardware Failure – Using a low wattage PSU can cause severe damage to the components of the computer. It can lead to hardware failures like a dead motherboard, failed GPU, or even a dead PSU.
● Computer Unable to Boot – A low wattage PSU might not be able to start the computer. It might not have enough power to start the components of the computer.
How to Determine the Wattage of PSU Needed for Your Computer?
The wattage of the PSU that is required by your computer depends on the components that it has. To determine the wattage required by your computer, you need to calculate the power consumption of all the components of your computer. Once you know the power consumption of all the components, you can determine the wattage of the PSU needed. Here is how you can calculate the power consumption of different components of your computer.
CPU – The power consumption of the CPU depends on its clock speed and the number of cores. The power consumption of the CPU is usually indicated in the specifications provided by the manufacturer.
GPU – The power consumption of the GPU depends on the model and brand. The power consumption is usually indicated in the specifications provided by the manufacturer.
Motherboard – The power consumption of the motherboard depends on the number of components that are connected to it. The power consumption is usually indicated in the specifications provided by the manufacturer.
RAM – The power consumption of the RAM depends on the frequency and the number of modules. The power consumption of the RAM is usually not that significant, but it is recommended to take it into account.
Storage Devices: The power consumption of storage devices usually ranges from 2W to 10W depending on the type of storage.
Once you have calculated the power consumption of all the components of your computer, you can add them to determine the total power consumption. The wattage of the PSU needed for your computer should be 30% higher than the total power consumption.
Conclusion
In conclusion, a low wattage PSU can harm your computer in several ways. It can lead to overheating of the components, low performance, hardware failure, and even the computer being unable to boot. The wattage of the PSU needed for your computer depends on the components that it has. It is recommended not to use a PSU that has a wattage lower than what is required. Always opt for a PSU that has a wattage that is higher than what you require to make sure that your computer runs smoothly and avoids any damages.
