The 720478-B21 HP 500-Watts Flex Slot Platinum 80 Plus Redundant Hot Swap Power Supply is designed to provide reliable and efficient power to Gen9 servers. It features a cooling and thermal management system that ensures optimal performance and prevents overheating.
The power supply uses a fan to dissipate heat, which is generated by the power conversion process. The fan is designed to run at a low noise level and can automatically adjust its speed based on the power load and temperature of the power supply. This ensures that the power supply maintains a cool operating temperature, even under heavy loads.
Additionally, the power supply has built-in thermal sensors that monitor the internal temperature of the power supply. If the temperature exceeds a certain threshold, the power supply will automatically shut down to prevent damage. This thermal management feature helps to protect the power supply and the server from overheating and potential damage.
The power supply also features a redundant design, which means that it has two separate power supplies installed in the same slot. This provides a backup power source in case one of the power supplies fails. This redundancy ensures that the server continues to operate even if one of the power supplies fails, providing added reliability and uptime.
