Choosing the Best Power Supply Brand 2020 – The Best PSUs You Can Buy Today

When setting up a workstation, a power supply unit (PSU) should be one of the first things you consider installing. That’s mostly because this component has to supply your computer’s internal circuitry with the exact or almost exact voltage at the right wattage for everything to work properly. Computer processors and memories are sensitive that way. So choosing the best power supply brand is not a luxury but more of a necessity.

What to Look for When Choosing the Best Power Supply Brand

For a long time, the common notion has been that buying a PSU with a higher total wattage is the best way to get better performance. The truth is that huge PSUs with something like 1800W are very useful when it comes to running computers that have multiple drives and that perform the graphics-intensive application. The problem is that they are often quite expensive.

Most computers don’t need that much power because they don’t often run at full capacity anyway. For the most part, if you are running a PC that has mid-level processors, graphics cards and RAM, you probably won’t need a PSU that has more than 600W. You can find out just how much you need by using online PSU power calculators.

That being said, here are some tips on what to look out for when shopping for the best power supply brand:

  • Look at the efficiency ratings: As a rule of thumb, highly efficient PSUs often have more effective components, thus making them consume less energy while producing less heat. This makes them much cheaper to operate. Look for PSUs that have an “80 Plus” certification signifying that they are at least 80% efficient.
  • Go for larger models: While they might be a little bulky, large PSUs have better cooling management and often run on advanced internal components making them more reliable.
  • Buy from a trusted brand: This should be a rule of thumb with every piece of machinery you buy. While this statement isn’t a condemnation on lesser-known brands, the simple fact is that trusted brands tend to take their “household name status” more seriously. This means that they will go above and beyond to stand up to the test, and even when their components fail, as some inevitably will, these brands have better warranty terms and more robust customer service systems in place. This will greatly reduce your level of frustration and even save you from cutting your losses and running.

Now that you know what to pay close attention to, let’s take a quick look at some of the best power supply units in the market today:
