Server Power Supply

When you are putting together the Server Power Supply you need for your company, there are many things to think about. 

One of the components you'll have to consider in the server's system is the electrical power source. 

But understanding the different power supply types can be confusing as there are platinum, titanium and gold power supplies and various powers and multiple power supplies...the list is endless. 

Finding a way to comprehend all of it can be not easy.

Below, we've explained some of the essential points you'll need to know to select the best power source suitable for the server. Read on to learn more.

How to find the proper power supply for your server?

If you're searching for the right power source to power your Dell or HPE server, there are online tools to use to find the proper power supply with the specific model of server you're using. 

For those who have HPE servers, There's an HPE Power Advisor service. If you're operating a Dell server, Dell offers its online service.

It's beneficial to be aware of what sets one type of power supply from the other before deciding.

• Server Power Consumptions

• Power Supply Performance

• Server Power Supply Efficiency

Server Power Consumptions

The more efficient a power source is and the lower the energy you'll consume in the long run. If you're running several in Rack Server, the savings in electricity costs could be significant over the time of the year.

Power supplies made of titanium provide the highest efficiency with 96 per cent power efficiency. Platinum power supplies are somewhat less efficient, at 94 per cent. 

Gold power supplies offer lower efficiency of 92%. Server Motherboard probably uses 50 to 150 watts, and each stick of memory requires about 15 watts. The processor needs between 80 and 140 watts of power.

Power Supply Performance

The effectiveness of a power supply is calculated based on the amount of AC (or, in some instances or some cases, DC) input power is required for the required output power. 

For example, a power supply that needs the power of 200W input to produce 180 watts output power will be evaluated with an efficiency of 90 per cent (180/200 is 0.9).

In addition to the cost of the power used in producing this energy, another drawback of poor power supplies is that the heat generated must be considered. 

The 20-watt difference between output and the input is converted into heat. You'll require cooling equipment to eliminate the heat.

However, the performance of a power source isn't uniform or even about the range of output. 

The majority of power supplies work at their highest efficiency when they're within the upper limits of their capacity. 

That means an 800-watt power supply that produces 400 Watts of power (50 per cent capacity) is less adequate than a power source with the same output of 400 watts power (80 per cent capacity).

Server Power Supply Efficiency

Selecting a power supply efficiency is crucial, but you need to be thinking about more than the efficiency for the source. 

If you can accurately estimate what power usage your server will consume, it is possible to select the proper power supply designed and operates with maximum efficiency.

Power supply will divide the supply chain funtion and passes to the various parts of the server, for example CPU, Server RAM and other units. Each parts requires different units of power supply for its performance. 

For large (enterprise-level) information centres, the cumulative energy losses from multiple servers with poor power supply configurations can be substantial. 

To obtain the most precise measurement, it's typically beneficial to configure and measure the system's actual load. But, this approach may not be practical for many customers since it involves buying, configuring, and running each part that makes up the server. 

In the end, customers who cannot conduct such tests could often be left with the power supply that is higher than the power they require.

Redundant Power Supplies

A Redundant Power Supply is used to provide a backup power source in case of failure of the main store. 

The presence of a redundant power supply in place is crucial for ensuring that you can function even in case of failure of the power supply that is your primary source.

In the case of redundant power sources, each server power supply is different. Some use the primary power supply to supply 100% of their energy requirements until it stops, after which they'll switch over to the second supply. 

Some will split their energy needs across both. It is also possible to set up your server power supply to use one of the two power sources.

Server Performance And Power Supply Efficiency

On one side, a power supply's efficiency rating can help know the power supply's performance. However, the specific system that the power supply works with could affect its performance.

As the case study illustrates, the same power supply can operate at different levels of efficiency in two servers. 

This study demonstrates that the Dell PowerEdge R720 is working more efficiently than the HP ProLiant, the DL380p; however, it will be different from one case to the next.

It's crucial to think about the noise level and the cost of running a specific power source.
