How to Choose the Best PC Power Supply?

Even if you don’t know anything about the specifications of a power supply, you still need to learn something about the importance of wattage. If you make the wrong choice, your computer won’t be functioning properly. What’s more, you might risk damaging several hardware components and shelling out your money on upgrades.

To avoid possible mistakes, try using special services that allow you to calculate power consumption. For instance, you can use eXtreme Power or other similar solutions. In most cases, it’s recommended to opt for a power supply with higher wattage power than you need.

It will help you avoid operating at 100% of the maximum load. If you want to better protect your computer, you can buy a 650 watt PSU if your power consumption equals 400.

Modular Support

This parameter is less crucial as it doesn’t significantly affect the performance of your device. Despite that, make sure to purchase a power supply with an easy-to-manage cabling system. Modular systems feature special connectors that come in handy when you need to connect a GPU and various components.

Fan Noise

Every PSU is prone to overheating under heavy load, which is why power supply units are fitted with special fans. If you prefer working alone and don’t want to be distracted by any sound, you will need to buy a PC power supply with noiseless fans. Larger fans are almost soundless as they don’t need to spin too quickly. However, a PSU with smaller fans might be more affordable.


  • • How many watts?

It depends on how many watts your computer consumes. Most gaming computers consume about 500W, so it might be a smart idea to purchase a power supply that supports 600-650W. Even if you decide to upgrade your system in the future, you won’t need to buy another PSU.

  • • What cables are the best?

There are three types of cables: hard-wired, partially and fully modular. The best power supply units come with modular cable systems as they are easier to organize.

  • • Which brand is the most reliable?

It’s better to choose a PSU released by one of the world-known manufacturers as such power supply units come with warranties. Besides, you can contact customer support if any issue arises. Corsair, Seasonic and Antec are considered to be the most reliable brands, but you should choose an option that suits your needs most.

  • • What is an 80 Plus rating?

80 Plus is a special rating system that allows one to see how effective a PSU is. It shows if a power supply unit can handle its tasks at 80% efficiency over its supported load range. If this rating is rather high, it means that a PSU is quite reliable. However, such power supply units come at hefty prices.
