What Is The Difference Between Bronze And Gold Psu?

Power supply units (PSUs) play an essential role in providing uninterrupted and safe power to a computer. When it comes to selecting a PSU for your PC, you’ll often come across the terms “bronze” and “gold.” These are efficiency ratings that help in determining the quality and performance of a PSU.

Bronze and gold are two different standards that determine the efficiency and cost of a power supply. A bronze PSU has an efficiency rating of 80% or more, while gold PSU is rated at 90% or more. The difference between the two ratings lies in how efficiently the PSU converts the AC power input from the mains into DC power that is used by the computer components. The higher the efficiency rating of a PSU, the less power it wastes as heat, which also translates into lower energy bills in the long term. In the next paragraph, we will delve deeper into the advantages and disadvantages of these two ratings when it comes to selecting a PSU for your PC.

What Is the Difference Between Bronze and Gold PSU?

A power supply unit (PSU) is responsible for supplying power to the different hardware components of a computer. There are different types of PSU available in the market, but two of the most popular ones are bronze and gold. Here’s a closer look at the difference between the two:

Bronze PSU:

• A bronze PSU typically has an efficiency rating of around 80%.
• It uses less efficient components.
• A bronze PSU is suitable for low to medium load systems.
• It has a lower price point compared to gold PSUs.

Gold PSU:

• A gold PSU typically has an efficiency rating of around 90%.
• It uses more efficient components.
• A gold PSU is suitable for high-end systems with heavy workloads.
• It has a higher price point compared to bronze PSUs.
• A gold PSU generates less heat and noise compared to a bronze PSU.

In summary, the main difference between bronze and gold PSUs lies in their efficiency ratings, components, price points, and suitability for different types of systems. A gold PSU is better suited for high-performance systems, while a bronze PSU is more suitable for low to medium load systems.


1. What is a PSU?
A PSU is a power supply unit that provides power to all the components in a computer system.

2. What is the difference between a bronze and gold PSU?
The efficiency rating is the main difference between them. A bronze PSU has an efficiency rating of 80%, while a gold PSU has an efficiency rating of 87%.

3. What does the efficiency rating mean?
The efficiency rating indicates the amount of power supplied to the components compared to the amount of power the PSU draws from the wall outlet. A higher efficiency rating means less power is wasted during this conversion.

4. Is a gold PSU worth the extra cost compared to a bronze PSU?
It depends on your usage and budget. A gold PSU is more expensive, but it can save you money on your electricity bill in the long run. It’s especially worth it for heavy usage and high-end systems.

5. What are some other factors to consider when choosing a PSU?
Other factors to consider include wattage, modular or non-modular, brand reputation, and certifications such as 80 Plus and safety regulations. It’s important to choose a reliable and high-quality PSU to ensure the safety and stability of your system.


In summary, the key difference between bronze and gold PSU lies in their level of efficiency. While bronze PSUs offer moderate efficiency, gold PSUs provide a higher level of efficiency. Additionally, gold PSUs are more expensive than their bronze counterparts. When choosing between these two options, it ultimately comes down to your budget, power needs, and desire for increased energy efficiency.
