Load Regulation
Load regulation refers to the regulation of output voltage changes in the event of load fluctuations. Especially in dynamic areas, the quality of a switched-mode power supply becomes apparent when it comes to keeping the output voltage as constant as possible even during violent changes in the output current. Especially with very small loads or with minimum input voltage and full load, very strong overshoots or even dips can occur in extreme cases, which may even lead to malfunctions or damage. Load regulation should be within 1% for 12 V, as well as for the slave rails (5 V and 3.3 V).
Ripple Suppression (Ripple Suppression)
Ripple suppression is good on all tracks.
Transient Response
Transient response is the amount of deviation in the output voltage as a result of a change in load. If the load changes, the power supply cannot immediately adjust to the new conditions and thus supplies either too much or too little stored energy. The Corsair RM1000x, one of the most powerful 1000W power supplies, is unattainable for the Pure Power FM 1000. The RM1000e performs better at 12V, the most critical rail, while it loses at the smaller rails. I would like to see the transient response closer to 1% on the 12 V rail and it works better on the 5 V rail.
