What is the 80 PLUS Bronze certification?

The 80 PLUS Bronze certification is an international standard that ensures the energy efficiency of a power supply unit (PSU), particularly in computer systems. It is part of the broader 80 PLUS program, which classifies PSUs based on their ability to convert electrical energy efficiently, minimizing energy loss as heat and improving the overall performance of the system.

To achieve 80 PLUS Bronze certification, a power supply must meet specific minimum efficiency requirements at different load levels:

• 82% efficiency at 20% load
• 85% efficiency at 50% load
• 82% efficiency at 100% load

This means that between 82% and 85% of the electricity consumed is converted into usable energy, while the rest is lost as heat. A PSU with this certification consumes less electricity and generates less heat, resulting in a quieter and more durable system.

Choosing a power supply with 80 PLUS Bronze certification ensures better energy performance compared to uncertified or entry-level models. It also tends to offer more stable voltage outputs, which is important for protecting sensitive components such as CPUs and GPUs.

While there are higher tiers within the 80 PLUS program (such as Silver, Gold, Platinum, and Titanium), the Bronze level offers an excellent balance between cost and efficiency, making it ideal for home users, gamers, and professionals looking for reliable performance without a high price tag.
