Kolink Classic Power 400 W Review
Fan Noise »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.
For such a budget-centric PSU, efficiency is quite high at all load ranges.
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.| Load Regulation & Efficiency Testing Data - Kolink Classic Power 400W | ||||||||||

This PSU doesn't struggle with 350 W at almost 35 °C ambient. I didn't put a load of 400 W on it, but instead followed my testing protocol, which had me apply a maximum load of 385 W at 37 °C, which the PSU also handled well.
Light Load Testing
In the following tests, we measure the PSU's efficiency at loads significantly lower than 10% 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 at Low Loads - Kolink Classic Power 400W | |||||||||

The fan spins at low RPM at light loads, and efficiency levels are high.
