Efficiency

Using the results we gathered, we plotted a chart showing the PSU's efficiency at low loads and loads ranging from 10 to 110 percent of the maximum-rated capacity.

Efficiency with normal loads is not competitive, but it is high in all other load ranges, including the 2% load test, where the unit achieves an impressive, close to 80%, reading.

10–110 % Load Testing

These tests reveal the PSU's load regulation and efficiency levels under high ambient temperatures and show how the fan-speed profile behaves under harsh operating conditions.

Light-Load Testing

We measure the PSU's efficiency at loads significantly lower than 10 percent of the maximum capacity—the lowest load the 80 PLUS standard measures. This is important when a PC is idle with its power-saving features turned on.

Super-Light Load Testing

We measure the PSU's efficiency with a 10 W load if its maximum power is 500 W or less in the following tests. We apply 2% of its maximum-rated capacity load if the PSU is stronger.

Super-Light Load Efficiency - Thermaltake Toughpower GF3 1000 W -115V
