The "80 PLUS Titanium" certification is a standard for power supply units (PSUs) that indicates high energy efficiency. To earn this certification, a PSU must achieve at least 90% efficiency at 20% and 100% load, and 92% efficiency at 50% load. This means that less energy is wasted as heat, making it a more environmentally friendly option. PSUs with the 80 PLUS Titanium rating are ideal for high-performance computers and servers, as they help reduce electricity costs and improve overall system stability. This certification is part of the broader 80 PLUS program, which includes other efficiency ratings like Bronze, Silver, and Gold.
