Do you use your desktop daily? If yes, then you should have a basic knowledge of the power supply unit. Let’s get some cool RGB power supply units for your PC today.

Many of us who use desktops and PCs every day need to be made aware of the importance and usage of the power supply unit. It might not be a very glamorous or exciting part of a PC, but it is its heart.

A power supply unit to a PC is what food is to humans. Supplying power to the PC is a vital task; not using a proper unit might cause much damage. 

Let us read about RGB power supply units and why we need them for our desktops.

What is an RGB Power Supply Unit?

For those new to the term RGB, it stands for red, green, and blue.

Why are we using RGB in power supply units (PSU)?

The answer is quite simple. We are using RGB in PSUs to make PSUs look more visibly attractive. 

The RGB lighting that can be put in various places, such as on the PSU case’s fan blades or even as an RGB ring around the fan, gives RGB Power Supply Units more customizability. Some products have a button on the PSU enclosure that you can press to change the lights. Some PSUs include features like Zero Fan mode that disable the fan when operating at low power for quiet operation. 

According to their power ratings and efficiency, these devices typically work at 100 to 240 volts and produce a wide range of power levels. The greatest of these power supply units (PSUs) incorporate high-performance capabilities with RGB customizability. The PSU is more resilient to power fluctuations and robust, thanks to high-quality components.

Importance of a PSU for desktop


Every PC’s foundation is made up of power supply components. These components transmit power throughout your PC by snatching it from the electrical socket. Your machine won’t perform as you need it to and could not even turn ON if it doesn’t have enough power.

Destabilization that might be difficult to pinpoint is one of the many issues that can result from a power source that does not deliver dependable or clean electricity. In fact, a failing power supply frequently results in additional issues like erratic resets and freezes that could otherwise go unnoticed. A PSU can safeguard components after a PC crash or offer fail-safes for errant currents in addition to providing power.

What should be the wattage of the PSU for your PC?

The power supply powers every component, and if you install the improper power supply, you risk damaging the components. Your components will receive constant energy from the proper PSU when required.

The finest power supply for your PC setup is the one that concurrently powers each component with the appropriate amount of watts. You must manually calculate this by dividing the sum of all component amps by their combined voltage. The overall number of watts needed for your PC construction is the outcome. 

Any PSU calculator will perform this for you and present a list of possibilities. You simply need to enter all the parts of the PC you are building into it. More complicated systems typically demand more electricity to operate. A desktop with multiple GPUs, a high-end motherboard, and a bespoke liquid cooling loop will require a higher capacity computer power supply than a more basic setup.

Modular vs. Non-Modular PSUs

When looking for power supply units, modular and non-modular are the two terms you will come across. A fixed set of wires is provided by a non-modular power supply and cannot be removed. You must leave those cords lying around in your case if your PC doesn’t require all of them.

It is possible to independently plug and remove each cable from a modular power supply. This implies that you can remove any cables you don’t need and store them in the box in case you do. You may reduce clutter, simplify cable management, and even improve ventilation by eliminating the need to locate a secure location to store unwanted wires within your case.

Power supply certification

It’s essential to consider several factors when buying a power supply to make the best decision. Power supply certifications assist in determining the PSUs’ energy consumption. 

The term “80 Plus” refers to power supply certifications. Many classes within the 80 Plus certification indicate the efficacy of each power supply: White, Bronze, Silver, Gold, Platinum, and Titanium. They are organized according to increasing levels of efficiency, starting with white and ending with titanium.

Crucial features for selecting the best RGB PSU

There are a lot of features you should look out for when buying an RGB power supply unit. Before purchasing, make sure the power supply is from a reputed company and read reviews to get the right one. Avoid generic, low-cost power supplies since they frequently have poor quality. Choose reputed companies with reliable support and guarantees. 


Using larger, heavier units are preferred over small, lightweight ones. The internal parts of higher-quality power supplies are always more significant, with better capacitors, chokes, and other parts. They frequently have larger heatsinks for better heat dissipation, all of which add weight. Another benefit is that bigger cooling fans often move more air while quieter than smaller ones.

You must verify the connections to ensure the PSU is compatible with your specific system. A connection that may serve as a 20-pin or a 24-pin connector is referred to as a 20+4 pin.

Also, look for three key characteristics when shopping for a power supply. These three characteristics are power output, rails, and efficiency. These three directly impact the performance of the PSU, while other characteristics and features are also significant.

Now that you have a good idea about RGB PSUs, let us jump to the list of some of the best ones you can purchase from the market.
