The "80 PLUS Bronze" certification is a standard for power supply units (PSUs) that indicates energy efficiency. To earn this certification, a PSU must achieve at least 82% efficiency at 20% and 100% loads, and 85% efficiency at 50% load. This means that less energy is wasted as heat, making it a more environmentally friendly option. In addition to energy savings, using an 80 PLUS Bronze certified PSU can lead to lower electricity bills. These power supplies are commonly used in computers and gaming systems, providing reliable power while ensuring that users benefit from improved efficiency and performance.
