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. I was expecting stronger load regulation at 12 V with the Corsair HX1500i.
Ripple Suppression (Ripple Suppression)
Ripple is low on all rails, with no additional internal cable caps, making cable routing and management a challenging task.
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 transient response of the HX1500i is within 1% at 12 V, which is actually very good, but the competition often performs better.
