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 power supplies can offer you the same.

Watt Power

To calculate how many watts 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 power supply 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 power supply.

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.

Efficiency Rate

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 power supply, 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.
