Power Supply Ratings

Power Supply Unit (PSU) ratings, specifications, and efficiency levels based on load.

Higher efficiency ratings result in less power loss reduced heat generation and lower energy consumption.

Rating	Specification	Efficiency by Load
80 PLUS	Specifies efficiency at different loads	Varies by certification level (80 PLUS Bronze, Silver, Gold, Platinum, Titanium)
80 PLUS Bronze	Minimum 82% efficiency at 20% load	82% at 20% load, 85% at 50% load, and 82% at 100% load
80 PLUS Silver	Minimum 85% efficiency at 20% load	85% at 20% load, 88% at 50% load, and 85% at 100% load
80 PLUS Gold	Minimum 87% efficiency at 20% load	87% at 20% load, 90% at 50% load, and 87% at 100% load
80 PLUS Platinum	Minimum 90% efficiency at 20% load	90% at 20% load, 92% at 50% load, and 89% at 100% load
80 PLUS Titanium	Minimum 90% efficiency at 10% load	90% at 10% load, 94% at 50% load, and 90% at 100% load
80 PLUS Titanium/Redundant	Similar to Titanium	Similar to Titanium, but for redundant power supplies

*The specific efficiency levels may vary slightly depending on the manufacturer and model of the power supply
