Features to Look for Before Buying a PC Power Supply
So, if you have a computer that requires more power because you are starting to do more and more intense tasks, you will need more power for them.
However, not all psus can offer you the same.
To calculate how many wattages of power you need, you should consider the number of components you have or that you will acquire over time. For this, you can choose to use an online calculator.
It will calculate the watts you need according to your components. Keep in mind that you will need a psu that has about 100 watts more of the result that the calculator gives you.
Active Power Factor Corrector
The Active Power function allows the energy needed to operate, to be distributed in a more efficient way. This function certainly manages to extend the life of your psu.
Modular and Non-Modular Cable System
Differences between the two may go unnoticed for some. It means that in a modular system, you can place and use only the cables you need to use. This will allow better organization and better air circulation so that your power supply is maintained at an adequate temperature.
The equation is simple; the higher the efficiency rate, the better the results will be. An efficiency rate of 90% means 10% of the energy is wasted as heat. The lower the efficiency rate, the more energy you will spend, which will be reflected in your next electricity bill.
80 PLUS Certification
This certification is related to energy efficiency levels. The higher the energy efficiency rate of a psu, the better the product will get.
This initiative is part of Ecos Consulting company, which is mainly responsible for developing this certification. The range of ratings ranges from Standard, Bronze, Silver, Gold, Platinum to Titanium.
Frequently Asked Questions
Can I install my power supply upside down?
The orientation of the power supply does not matter. Its fan must be able to expel the air successfully, without anything obstructing the passage of the airflow.
My computer does not turn on, can it be because of my power supply?
You should check that the output voltages are within the nominal value range. In case the problem continues, it could be due to damage to the motherboard or software.
My computer turns on but does not start. Is it due to my power supply?
In this case, you must perform the same procedure. Verify that the output voltages are within 5% of the nominal value
