Benefits of Using Power Suppliy

The PWS-2K04A-1R Supermicro 2000 watt high-efficiency redundant power supply offers several benefits, including:

  • High efficiency: The power supply has a high efficiency rating, which means that it converts more of the input power into useful output power, and less is wasted as heat. This can help to reduce energy costs and improve the overall energy efficiency of the system.
  • Redundancy: The power supply is redundant, meaning that it has two separate power modules that can provide power to the system. This can help to increase the reliability and availability of the system, as if one power module fails, the other can take over and keep the system running.
  • High power output: The power supply can output up to 2000 watts of power, which can provide enough power for high-performance systems with multiple CPUs, GPUs, and other power-hungry components.
  • Hot-swappable: The power supply is hot-swappable which means it can be replaced without shutting down the system, this can help to minimize downtime and increase system availability.
  • Compatibility: The power supply is compatible with a wide range of Supermicro servers, which can make it easier to integrate into existing systems.
  • Power Factor Correction (PFC): The power supply has active PFC which can help to improve the power factor, reduce harmonic distortion and increase overall power efficiency.

Installation and Maintenance


  • Begin by unboxing the power supply unit and verifying that all components are present and in good condition.
  • Carefully read the user manual before proceeding with the installation.
  • Connect the power supply unit to the server by plugging in the appropriate cables.
  • Ensure that all connections are secure and properly aligned.
  • Turn on the power switch for the server and monitor the power supply unit for proper operation.


  • Regularly check the power supply unit for any signs of physical damage or wear.
  • Monitor the power supply unit's temperature and ensure that it is operating within the recommended range.
  • Clean the power supply unit regularly to prevent dust and debris buildup.
  • Check the power supply unit's output voltage and ensure that it is within the acceptable range.
  • Replace the power supply unit if it shows signs of failure or if it is no longer able to provide the necessary power to the server.
  • Regularly check the power supply unit's fan and ensure that it is functioning properly. If the fan is not working, it should be replaced.
  • Lastly, keep the power supply unit in a cool and dry place. It's important to follow the manufacturer's recommended maintenance schedule for the power supply unit to ensure optimal performance and longevity.

High Efficiency and Power Savings

The PWS-2K04A-1R is a 2000 watt high-efficiency redundant power supply from Supermicro that is designed to be energy efficient and save power. The high efficiency rating means that it converts a higher percentage of the input electrical power into usable power for the computer, reducing the amount of power wasted as heat. The redundant design means that it has multiple power supply units, allowing for automatic failover in case one unit fails. This can help to ensure that the computer continues to function even if there is a problem with one of the power supply units. Additionally, the power savings come from the fact that the power supply is able to adjust its power usage based on the load it is under, reducing power consumption when the computer is idle or under light load.

The cost of electrical energy continues to rise even when there is an ever-increasing demand for more electrical power to run servers. People are also becoming more aware of their environmental footprints, making an efficient server power supply more than just a necessity. Such a power supply can keep your servers up and running without failure with less energy wastage.

The Power Supply You Need for the Servers

As mentioned in the introductory part, you need a highly efficient server power supply. That is the only way you can keep your server running while taking less space and consuming less power. You need a type of power supply that offers a redundancy option. That is to say, it should have two power supply units where the first unit acts as a backup in case the other fails. That configuration will enhance the reliability of your server.

With high efficiency of over 90%, you will not have to worry about hiked utility bills and backup battery bank management. You can monitor everything and be in charge at every stage.

Server Power Supply at the Best Price

Take advantage of the high energy efficiency of the power supply while saving on the total cost of ownership. These power supplies have standardized features that allow for both redundancy and non-redundancy power configurations. They are hot-swapped power supplies that let you change from one PSU to the next without shutting down the server. are also

Low Operational Cost

Many server managers spend a significant amount of resources trying to keep the server rooms under optimal temperature, which increases the operation cost. You can counter that by using more efficient server power supplies. Remember that the heat is a result of wasted power. With efficient power supplies, this wasted power is kept at its minimum, reducing the need for elaborate cooling.
