In practical operation, a PSU is constantly subjected to changing loads, depending on the activity of the CPU, GPU, and other system components. To properly evaluate performance under such conditions, our reviews include transient load testing.
Our procedure is as follows: while the PSU operates at a steady 20% and 50% load, we apply a transient load of 10 A at +12 V, 5 A at +5 V, and 5 A at +3.3 V for 200 ms. Each test is repeated 50 times at a rate of 5 Hz. This allows us to observe how well the unit can maintain regulation under sudden load fluctuations.
