Power Efficiency and Energy Savings

The 865408-B21 HPE 500Watt Power Supply for the Proliant DL380 Gen10 is designed for power efficiency and energy savings. This power supply is equipped with advanced power management features that enable it to adjust its power consumption based on the system's needs. This ensures that the power supply is only consuming the amount of power that is necessary to run the system, reducing the overall power consumption and energy costs.

Additionally, the 865408-B21 HPE power supply is also equipped with a high efficiency rating, which means it is able to convert a higher percentage of the input power into useful power for the system. This results in less wasted power and further energy savings.

Another feature of this power supply is its ability to operate in different power modes, including power-saving mode and high-performance mode. In power-saving mode, the power supply reduces its power consumption to minimize energy usage, while in high-performance mode, it increases power consumption to support high-performance workloads. This allows for further customization and control of power consumption, leading to even more energy savings.

Safety and Compliance

The 865408-B21 HPE 500Watt Power Supply for Proliant DL380 Gen10 is designed to meet safety and compliance standards for use in data centers and other professional environments.

First, the power supply has been tested and certified by various agencies such as UL, TUV, and CE to ensure it meets safety standards for electrical equipment. This includes standards for electrical shock, fire hazards, and electromagnetic compatibility.

Additionally, the power supply is compliant with energy efficiency standards such as 80 PLUS Platinum, which ensures that it is highly efficient and reduces energy consumption and costs.

It also meets various environmental standards such as RoHS, which prohibits the use of certain hazardous substances in the manufacturing of the power supply.

In terms of compliance, the power supply is compatible with the Proliant DL380 Gen10 server, which means it meets the power requirements and specifications of the server and will function properly when installed.

Cooling and Thermal Management

Cooling and thermal management are important factors to consider when using the 865408-B21 HPE 500Watt Power Supply for the HPE ProLiant DL380 Gen10 server. The power supply unit (PSU) is designed to dissipate heat generated during operation, and proper cooling and thermal management can help ensure that the PSU is able to function efficiently and effectively.

One way to manage the cooling of the PSU is by using a fan. The 865408-B21 HPE 500Watt Power Supply is equipped with a built-in fan that helps to dissipate heat generated by the PSU. The fan is designed to automatically adjust its speed based on the temperature of the PSU, which helps to keep the PSU cool and functioning properly.

Another way to manage the thermal performance of the PSU is by using thermal management software. This software can monitor the temperature of the PSU and adjust the fan speed accordingly. This can help to ensure that the PSU is operating within safe temperature ranges and can help to prolong the life of the PSU.

Additionally, proper airflow management within the server can also help to keep the PSU cool. This can include ensuring that there is adequate airflow around the PSU and that any other components or systems that generate heat are properly cooled.
