80 Plus Bronze Vs Gold

When it comes to building a PC, one of the most critical components is the power supply unit (PSU). It is responsible for providing electricity when a computer is turned on, and without it, the whole system is useless. The efficiency rating of a PSU is an important factor to consider when purchasing one. In this article, we will discuss the differences and similarities between 80 Plus Bronze and Gold power supplies.

Before we dive into the details, let us first understand what 80 Plus certification is. It is a certification program developed by the non-profit organization, Electric Power Research Institute (EPRI). The program is designed to measure and certify the energy efficiency of power supply units for personal computers.

There are currently six certification levels in the program, listed in the order of increasing efficiency: White, Bronze, Silver, Gold, Platinum, and Titanium. The 80 Plus White certification requires a PSU to have at least 80% efficiency at 20%, 50%, and 100% loads, while Titanium certification requires at least 90% efficiency at 20%, 50%, and 100% loads.

Now, let us focus on 80 Plus Bronze and Gold certification levels. An 80 Plus Bronze certified PSU must have at least 82% efficiency at 20% load, 85% at 50% load, and 82% at 100% load. On the other hand, an 80 Plus Gold certified PSU must have at least 87% efficiency at 20% load, 90% at 50% load, and 87% at 100% load.

What does this mean in practical terms? A PSU with higher efficiency means that it wastes less energy as heat and converts more of the electricity it draws from the wall into usable power for the computer components. This translates into lower electricity bills, less heat generated by the PSU, and a longer lifespan of the components.

However, the efficiency rating is not the only factor that determines the quality of a power supply unit. Other aspects such as voltage regulation, ripple suppression, and build quality are also crucial. A poorly made PSU, even if it has a high efficiency rating, can still cause instability, crashes, and even damage the computer components.

Now, let us compare the advantages and disadvantages of 80 Plus Bronze and Gold power supplies.

Advantages of 80 Plus Bronze

1. Affordability: Compared to Gold and Platinum certifications, Bronze PSUs are more affordable, making them a good option for budget builds. They are widely available from reputable brands such as Corsair, EVGA, and Seasonic.

2. Efficiency: While Gold certified PSUs are more efficient, Bronze certified PSUs still meet the 80 Plus standard, which means they are reasonably efficient and can save you money on your electricity bills compared to non-certified PSUs.

3. Availability: Since Bronze certification is the minimum requirement for many institutions, including the USA Federal Government, Bronze certified power supplies are widely used in pre-built computers, servers, and data centers. This means that they are more readily available in case you need a replacement PSU.

Disadvantages of 80 Plus Bronze

1. Lower efficiency: While Bronze certified PSUs are efficient, they are not as efficient as Gold certified PSUs, which means they generate more heat, noise, and have a slightly shorter lifespan.

2. Limited features: Bronze certified PSUs typically have fewer features such as modular cables, fanless operation, and high-quality capacitors.

Advantages of 80 Plus Gold

1. Efficiency: Gold certified PSUs are significantly more efficient than Bronze certified PSUs, which means they emit less heat, use less energy, and last longer.

2. High-end features: Gold certified PSUs usually come with additional features such as modular cables, fanless operation, and high-quality capacitors, which improve their overall performance and reliability.

3. Future-proofing: As the demand for energy-efficient computing continues to grow, investing in a Gold certified PSU is a smart long-term decision since it will still be relevant and efficient for years to come.

Disadvantages of 80 Plus Gold

1. Higher cost: Gold certified PSUs typically cost more than Bronze certified PSUs. This may deter some budget-conscious builders from opting for the Gold certification.

2. Availability: Since Gold certification is more rigorous and specialized, there are fewer PSU models available in the market with this certification.


80 Plus Bronze and Gold certifications are two of the most popular efficiency standards for power supply units. While Gold certified PSUs are more efficient and come with more features, they are also more expensive. Bronze certified PSUs, on the other hand, offer a good balance of affordability and efficiency and are widely available. Ultimately, the decision between Bronze and Gold certifications depends on your budget and the specific needs of your system. However, regardless of the certification level, it is crucial to invest in a high-quality, reputable brand PSU that meets your system’s power requirements and has adequate safety features.
