The "80 PLUS Silver" certification is a standard for power supply units (PSUs) that indicates high energy efficiency. To earn this certification, a PSU must achieve at least 85% efficiency at 100% load, 88% at 50% load, and 82% at 20% load. This means that less energy is wasted as heat, leading to lower electricity bills and a reduced environmental impact. PSUs with the 80 PLUS Silver rating are ideal for gamers and professionals who require reliable performance from their computers. By choosing a certified unit, users can ensure that their systems run efficiently, contributing to longer component lifespan and better overall system stability.
