Does PSU Brand Matter? (Brands To Choose & Brands To Avoid)

Choosing the right Power Supply brand can be confusing for those who are new to building PCs.

This article will help you decide which Power Supply brand to choose and which ones to stay away from and explain why your choice of Power Supply brand is important.

It’s important to buy a power supply from a reputable brand because they use high-quality components; therefore, your PSU runs better and lasts longer.

Let’s dive deeper into why the Power Supply brand matters-

Why PSU Brands Matter?

Here are some reasons why it’s important to pick a power supply from a reputable brand-

Internal Components

There are several small components inside the Power Supply, such as voltage regulators, bridge rectifiers, transformers, transistors, main filter inductors, main control IC, fuse, etc.

The most essential internal components inside the PSU are the capacitors. Power Supply from a reputable brand comes with Japanese capacitors.

Japanese capacitors make power supplies more efficient, which means less heat and longer lifespan, and these Power supplies with Japanese capacitors are better than Power Supplies with Chinese capacitors.

Besides the capacitors, the power supplies from reputable brands also have high-quality fans that help to cool down the power supply and the rest of the PC system.

Efficiency Ratings

Power supply efficiency is one of the reasons why we should buy a power supply from a reputable brand. The majority of the PSUs from reputable brands come with an efficiency between 80% and 90%; therefore, these PSUs are more reliable than the other unbranded PSUs.

Let’s dive deeper into why PSU efficiency matters-

The efficiency of the computer Power Supply is its output power divided by its input power; the remaining input power is converted into heat.

Let’s take some examples-

A 600W Power Supply with 60% efficiency ratings running at full load would draw 1000W from the mains and therefore waste 400W as heat.

On the other hand, a 600W Power supply with 80% efficiency ratings would draw 750W from the mains, therefore only waste 150W as heat.

The unbranded PSUs come with 50-60% efficiency, but PSUs from a reputable brand come with efficiency ratings between 80-90%. You can learn more about this Power Supply efficiency in depth.


The lifespan of a power supply is an important factor to consider when buying one, as it gives us the confidence to choose a brand that we can trust for the long term.

Unbranded power supplies often have no warranty or a very short warranty, while power supplies from reputable brands typically have a warranty of 5-10 years. That’s why it’s important to buy a power supply from a reputable brand.
