1500W PSU Notice About the Noise: High-frequency noise may occur when the PSU is unloaded. This is due to the PWM control chip adjusting cycles to reduce power consumption. The noise generation varies with the production process of the transformer. The fan might generate a loud sound, especially at high temperatures, even when the PSU is unloaded. These phenomena are normal. It is advisable to turn off the AC switch when not in use. If noise is a concern, consider not purchasing this product. Note This set is pre-assembled and ready for AC power connection. Available plug types: US, EU, UK. Differences lie only in the AC cable and voltage requirements. WiFicard and CR1220 battery for date/time display are not included. WiFicard installation requires a battery, and removal after installation is not recommended.
