How to Choose the Right Power Supply for Your Server

When it comes to the process of assembling the server you need for your company There are lots of things to think about. One of the numerous 400 watt power supply  that you’ll require in your server’s infrastructure is a power source. Understanding the differences between power supply types can be confusing as there are platinum, titanium, and gold power supply, various capacities and multiple server power supply…the list of options is endless. It can be difficult to understand, everything isn’t easy.

Below, we’ve explained the essential points you’ll need to know to select the correct power source for your server. Continue reading to find out more.

Finding The Power Supply You Need

If you’re in search of an energy source that will work with you Dell or HPE server There are tools online that you can utilize to find an appropriate power source with the specific model of server you’re using. For those who have HPE servers you can use an HPE Power Advisor service. If you’re using an Dell server, Dell offers its own online service.

However, it’s beneficial to be aware of what sets one type of power supply from another in making your decision.

Server Power Supply Efficiency

In general, the more efficient the power supply is more efficient, the less energy you’ll consume in the long run. If you’re running several servers in a rack and you save on electricity, the costs could be significant over the time of the year.

Titanium power supply is the most efficient that offer 96 power efficiency. Power supplies made of platinum are less efficient, at 94 percent. Gold power supplies have lower efficiency at 92 percent.

In essence, the effectiveness of a power source is determined by the amount of AC (or in some instances DC) input power is required to generate the required output power. For instance, a power supply that requires the power of 200W input to generate 180 watts of output power will be evaluated with an efficiency of 90 percent (180/200 equals 0.9).

The 20-watt difference between the output and the input is converted into heat. Apart from the additional cost of the electricity used in the production of this energy, another drawback of power supply systems that are inefficient is that this heat must be taken into account, and you’ll require cooling equipment to eliminate the heat.

Naturally, the effectiveness of a power source isn’t linear or even flat in relation to its output range. The majority of power supply are 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 percent capacity) will not be as productive as an 800-watt power source offering the same output power (80 percent capacity).

Why is this important? When selecting a power source, efficiency is a key factor, but you need to be thinking about more than the efficiency of the source. If you can accurately estimate what power usage your server will consume on your, it is possible to select an appropriate power supply measured and will operate with maximum efficiency.

For large (enterprise-level) information centers, the cumulative energy loss due to multiple servers operating inadequate power supply configurations could be substantial. For the most precise measurement, it’s typically beneficial to configure and measure the actual performance of your system. But, this approach isn’t practical for all clients since it requires buying, configuring, and running each part that makes up the server. In the end, customers that aren’t equipped to run these tests may often be left with an energy source that is greater than the power they require.

Redundant Power Supplies

The redundant power supplies serve to act as a backup source in case of failure of the primary power source. The presence of redundant power supply in place is crucial for the ability of your business to continue to run even in case of failure of the main power supply.

In the case of redundant power supply, every server is different. Some servers will make use of the primary power supply to supply 100% of they’re the power requirements until it stops, after which they switch to the second supply. Some will split their energy requirements among both. It is also possible to alter the way you’d like your server to make use of both power sources.

Server Performance And Power Supply Efficiency

On one the other hand, a power source’s efficiency rating can be helpful in understanding the performance of the power supply. But however, the specific system that the power supply works with will affect its performance.

This case study illustrates that the same power supply will operate at different efficiency on two different servers. This particular study shows Dell Power Edge R720 as operating more efficiently than the HP Pro Giant DL380p however, this can vary depending on the particular the case.

How Much Will It Cost To Run My Server?

It’s crucial to think about both the noise level as well as the cost of running a certain power source.

This chart is a great way to compare the price and the level of noise generated by different servers for certain power supply.

To determine the cost of running your server’s power There’s a straightforward formula you can employ. Multiply the number of watts times the amount of time used (per day, month or even a year, depending on how you want to determine) and then divide that number by 1000. Then, divide the result by the cost of electricity per Kilowatt-hour. The result will provide you with an estimate of the total cost of running the power source.
