Intelligent Power Management

Intelligent Power Management (IPM) is a feature of the 720620-B21 HPE 1400-Watts Flex Slot High Efficiency Platinum Plus Hot Swap Power Supply that allows for efficient and effective management of the power being consumed by the system. IPM is designed to monitor the power usage of the system and adjust the power supply accordingly to ensure that the system is running at optimal efficiency.

This power supply has several different modes that it can operate in, including a high-efficiency mode, a power-saving mode, and a power-saving standby mode. When the system is in high-efficiency mode, the power supply will operate at its maximum efficiency, providing the most power to the system while consuming the least amount of energy. In power-saving mode, the power supply will reduce its output to conserve energy and reduce power consumption. The power-saving standby mode is designed to reduce power consumption even further, and is typically used when the system is not in use.

IPM also includes several safety features to protect the system from power surges and other potential power issues. It includes over-current protection, over-voltage protection, and short-circuit protection to ensure that the system is protected from any potential power issues.

Power Efficiency and Output

The 720620-B21 HPE 1400-Watts Flex Slot High Efficiency Platinum Plus Hot Swap Power Supply is a high-performance power supply designed for use in data centers and other high-demand environments. It is designed to be highly power efficient, with a Platinum Plus rating, which means it meets the highest energy efficiency standards set by the 80 Plus organization.

The power supply has a 1400-watt output, which is capable of powering high-demand devices and systems. It is also designed with a hot-swap feature, which allows for easy replacement of the power supply without having to shut down the system. This feature is particularly useful for data centers and other critical systems where downtime is not an option.

The Flex Slot design allows for easy integration into a variety of systems and equipment, making it a versatile option for a variety of applications. Additionally, the power supply is built with high-quality components and undergoes rigorous testing to ensure reliability and longevity.


The 720620-B21 HPE 1400-Watts Flex Slot High Efficiency Platinum Plus Hot Swap Power Supply is a high-performance power supply that is designed for use in HPE ProLiant servers. This power supply offers several key features that contribute to its high performance, including:

  • High efficiency: The power supply is rated at Platinum Plus efficiency, which means it can convert up to 94% of the incoming AC power into usable DC power for the server. This reduces the amount of heat generated by the power supply and improves overall system efficiency.
  • Flex Slot design: The power supply is designed to fit into a Flex Slot, which allows for more flexibility when configuring the server. This means that the power supply can be easily swapped out or replaced without having to reconfigure the server.
  • Hot Swap capability: The power supply can be removed and replaced while the server is running, which helps to minimize downtime. This is particularly useful in critical applications where server uptime is essential.
  • High power output: The power supply is rated at 1400 watts, which is more than enough to power most servers. This provides a high level of power redundancy and ensures that the server has enough power to handle heavy workloads.
  • Safety features: The power supply is designed with multiple safety features to protect the server from overvoltage, overcurrent, and overheating. This helps to ensure that the server remains stable and reliable even under heavy loads.

Many people have resorted to networking as the best alternative to services. There is a growing demand for a reliable networking system that will make it possible to collaborate and share data over the network. As a result, power outages and downtimes are undesirable. If you want to make your system more reliable and immune to disruptions, then buy a power module.

Obtain Increased Power and Cooling with Power Modules

Most of the power modules, such as the 15454-M6-AC Cisco AC power supply, have a total of 8 slots: two for redundancy and 6 for line card slots. These slots provide improved power cooling capabilities to keep the system running under optimal conditions. The form factor is also a universal one that can be mounted on any server rack in any part of the world.

Easy Installation on the Racks

Power modules can be designed to easily mount onto the racks. Some can easily sit on 19-inch, 21-inch, or 23-inch racks, but that depends on the power control module model in question. Each rack size has its design for airflow, which affects how you mount these power modules onto them. Installing power modules is never a difficult task, but you might need technical assistance if you are less experienced.

Warning Alarm for Failed Components

A power module always comes with fans for cooling. The number of fans that you will find in any module also depends on the model. Some power modules have one, two, three, or more fans. The fans are carefully monitored, and a failure of any of them triggers an alarm. For a multi-fan power module, the speeds of other fans are increased to compensate for the faulty one.

Power Modules Designed for Specific Applications

You cannot use just any power module for your system. You need to find the right one for the intended purpose. For example, if your system is HPE ProLiant D-series, then the appropriate power module to buy is 738024-B21 HP power supply. That should apply to any other model because they have different output power ratings.
