Efficiency

Using the results we gathered so far, 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 is high enough with normal loads, but low with light loads.

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.

I tested 100%, but not 110% load because the 3 kVA UPS connected to the 4 kVA AC Source had a problem keeping up. I should upgrade the UPS, but a quality 4 kVA UPS isn't exactly cheap. Efficiency of the M2000 under harsh conditions is amazing for its capacity.

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 for when a PC is idle with its power-saving features turned on.

Efficiency is incredibly low with light loads.

The 5VSB rail is highly efficient.
