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.




This is an efficient platform, especially 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.


This PSU doesn't have any problems delivering high loads at increased operating temperatures, but noise output does go through the roof.

Light Load Testing

In the following tests, 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 levels are high at light loads, and noise output is minimal since the PSU's fan doesn't spin up.

Ultra-Light Load Testing

The applied load in this test is only 10 W for PSUs with 500 W and less capacity. This is because we dial in 2% of the maximum-rated capacity for all other PSUs and only run this test with 115 V input.


The PSU is too far from the 70% efficiency mark with 2% load.

5VSB Efficiency

The 5VSB rail is not efficient enough, which FSP should improve.

Power Consumption in Idle and Standby

Power consumption is very high in standby with 230 V input.
