Unfortunately, not all PC builders or computer users give power supplies the attention they deserve. They simply assume that as long as the PSU presents the desired voltage, it will work well with their PC. It’s important to clarify that it’s not that simple.
In this blog post, we’ll be diving into the sometimes shocking truth about inadequate power supplies and how they can negatively impact your PC. From a detailed explanation of what a PSU is to how to select one that will provide adequate power for your system, we have got you covered. We’ll also be answering some frequently asked questions about PSUs.
Before we dive in, here is a quick summary of what to expect.

Now, let’s dive into the nitty-gritty of PSUs and how they can doom your PC.
1. What is a Power Supply Unit?
A PSU is an internal component that provides power to other components inside the computer. The PSU is connected to the motherboard, and the voltage is transmitted to other components such as the hard drive, the processor, and the graphics card. The PSU also includes a fan that cools internal components.
2. Why You Need An Adequate Power Supply Unit
An adequate power supply unit allows the computer to run smoothly without any interruption. When the PSU is not supplying adequate power, the computer may operate irregularly and even be damaged. In some situations, the PSU may shut down or cause the system to crash.
3. How Inadequate Power Supply Units Impact Your PC
a. Overheating
When the PSU does not supply enough power, it increases the system’s workload. As a result, the hard drive, processor, and graphics card may overheat. If your computer’s internal components overheat, it can damage them, and ultimately shorten their lifespan.
b. Random Shutdowns
Inadequate power supply units can cause computers to shut down without warning. This happens when there is not enough power to keep the system running or there is a surge that stops the power supply temporarily. Random shutdowns can be frustrating, primarily if they occur while you are working on something important.
c. Hardware Damage
An inadequate PSU can also cause damage to critical hardware components. Suppose the PSU cannot supply the correct amount of power to the system. In that case, there is a risk of damaging the hard drive, graphics card, and other internal components.
4. How To Select An Adequate PSU
a. Wattage
The wattage of the power supply unit must match the power requirements of your PC. You can find the wattage requirements by checking the manual that came with the motherboard or graphics card. The more components the computer has, the higher the required wattage. If the PSU cannot supply enough power for the system, your PC can experience random shutdowns, overheating, or damage hardware.
b. Efficiency
The efficiency refers to how much power the PSU can perform at a particular temperature and load level. The higher the efficiency, the lower the energy wasted, and the less heat generated. A high-efficiency PSU is perfect for computers that are run for extended periods, such as gaming rigs or servers.
c. Modular or Non-Modular
Modular PSUs are more expensive than non-modular ones, but they are more flexible. The modular PSU allows the user to detach and attach cables, depending on the need. As a result, it can reduce the number of cables in the computer, increasing the airflow and reducing the chances of overheating.
5. Frequently Asked Questions
Q: Can a power supply unit be repaired?
A: Yes, a PSU can be repaired if there is a minor fault. However, PSU repairs are best left to specialists. DIY repair can cause more damage or put you at risk of electrocution.
Q: Is it necessary to use a high wattage power supply unit?
A: No, it’s not necessary. The wattage of the PSU should match the PC’s needs. Choose a unit that is slightly higher in wattage than the calculated number to avoid shortening the PSU’s lifespan.
Q: What happens when you connect an inadequate PSU to a PC?
A: When you connect an inadequate PSU to a PC, you may experience random shutdowns, overheating and risk damaging critical hardware components.
Conclusion
Investing in a high-quality power supply unit is just as important as investing in other components when building a PC. It’s critical to ensure the PSU meets the specifications required by your computer components. Inadequate PSUs can shorten component lifespan, cause random shutdowns, and damage hardware.
