An increase in common mode noise within a data center's power supply primarily generates heat. Common mode noise refers to unwanted electrical noise that is present equally on all conductors with respect to a common ground. This noise can cause disturbances in the power supply system, resulting in inefficiencies.

As common mode noise increases, it can lead to fluctuations in electrical signals, which can elevate the operational temperature of components within the power supply. These fluctuations may cause components to work harder to maintain stable performance, leading to increased power dissipation in the form of heat. This is often seen in power transformers, capacitors, and other electrical components that may not handle the excess noise effectively.

Ultimately, excessive heat generation due to common mode noise can also affect the reliability and longevity of the equipment within the data center, highlighting the importance of noise management in maintaining efficient and safe operations.
