Psu Efficiency Curve
A precise tool.
What is the Psu Efficiency Curve & How does it work?
Power Supply Unit (PSU) efficiency is a critical factor in determining the overall energy consumption and cost-effectiveness of a computer system. The PSU converts AC power from the wall into DC power that components like the CPU, GPU, and storage devices can use. Efficiency is typically measured by the ratio of output power to input power.
The 80 Plus certification program defines several efficiency levels based on the PSU’s performance under various load conditions. For instance, an 80 Plus Bronze certified PSU must maintain at least 80% efficiency at 20%, 50%, and 100% of its rated power output.
eta = frac{P_{out}}{P_{in}}
eta = Efficiency, P_{out} = Output Power, P_{in} = Input Power
