How Much Electricity Does A Server Use?

Some racks can now reach 20kW, depending on the data center, although the average is closer to 7kW. As the demand for data centers has grown and continues to grow, cooling and ventilation has become a significant barrier for high-density server functioning.

What is the cost of running a server in terms of electricity?

At rest, newer two-socket x86 servers with up to eight core CPUs will consume 150 to 200 watts. This energy consumption might double to 400 watts when fully utilized.

A two-socket server can require anything from 1,314 kWh per year (only to turn it on) to 2,600 kWh per year in terms of annual energy consumption.

Allowing for changes in workload demand, a two-socket server’s typical annual power consumption is roughly 1,800 to 1,900 kWh.

Servers are supposed to function 24 hours a day, seven days a week, although most desktops and laptops are not. Here’s how much power these systems would consume if they ran continuously.

Desktop computers require between 45 and 90 watts, therefore they would use between 394 and 788 kWh a year if they ran 24 hours a day, seven days a week.

A laptop with a power consumption of 30 to 75 watts will consume between 262 and 657 kWh per year.

According to Davidson, power efficiency is improving with new generations of semiconductors, which use technologies like speed step to dynamically modify the chip’s clock rate to save power.

The daily kilowatt-hour (kWh) consumption is calculated by multiplying the wattage by the number of hours consumed per day.

Utility bills are determined by multiplying the cost by the number of kWh consumed. According to the United States Environmental Protection Agency, a system that uses 394 kWh at 8.5 cents per kWh costs $33.51 a year.

How much power does a home server consume?

When it comes to building your own home server, you have a few options. On eBay, you could find an ancient enterprise-grade server, such as this HP DL360. These servers frequently feature sufficient RAM, high computing power, and support RAID setups.

The disadvantage of these servers is that they generate a lot of noise and consume a lot of power. Replace the fans with quieter models, such as this from Noctua.

These devices, however, are overrated for most home server settings. However, an old laptop or desktop computer is a terrific place to start.

If you want to create your own home server, there are a few things you need think about:

  • Storage capacity is required.
  • Consumption of energy
  • Options for mounting (rack or not)

Low Power Home Server

I’ve compiled a parts list for you to build your own low-power home server. It should use roughly 10 watts while idle and around 20 watts when running a couple of servers. Hard drives need the most energy, thus the more you add, the more energy you’ll use.


A home server doesn’t require a lot of processing power; an Intel G5400 will suffice in most circumstances. However, the I3 is not much more expensive, has lower power consumption, and provides that little bit of more in case you need it.


Choosing the appropriate motherboard can significantly reduce your server’s power consumption. The Fujitsu motherboard is extremely energy efficient, thanks to the fact that it disables functionality it doesn’t use.

The disadvantage of this motherboard is that it is difficult to come by and is fairly pricey. There are two types available on the market: the D364x-B line has six SATA connectors while the -H line has four.


If you’re solely utilizing Docker images, you won’t require much memory. In those circumstances, 8GB would be more than plenty.

Try to limit yourself to just one memory module, as each additional module increases memory use.

Power Supply

The picoPSUs are excellent power supplies for constructing a low-power home server. The 160 watt version is offered, but the 90 watt version should suffice with the I3-9100.

With the picoPSU, you’ll need to utilize an external power adapter, which is indicated above.

SSD and Storage Disks

SSDs are ideal for use as a boot disk and for storing and installing servers and programs. The NVMe SSD consumes somewhat more energy than standard SSDs, but it allows us to use the four SATA slots for storage.

The Intel and Samsung SSDs use the least amount of electricity. I have a 500GB version advertised, which should be sufficient to run your servers.

We use standard spindle disks for storage. The benefit of 2.5-inch hard drives is that they consume significantly less power than 3.5-inch counterparts.


There are a handful of alternatives on the market if you don’t want to build a home server from the ground up. The Intel NUC, for example, is a terrific compact but powerful system to begin started with.

A Raspberry Pi 4 is also a good place to start. These are quite inexpensive and make excellent little devices for running small programs or services.

A Synology NAS is another popular option for a home server. Although they are primarily NAS (network-attached storage) devices, they are also excellent platforms for running your home server. Synology has a large community with many fascinating and useful apps that you can easily install on your Synology.

Check to see if the model you’re considering buying can run Docker images. The DS220+, for example, is a solid entry-level Synology device.

How much does it cost to run a server 24 hours a day, 7 days a week?

Depending on how you scale and the game you’re playing, renting a server might cost anywhere from $5 to $150 per month.

Running the server, on the other hand, is a different affair. You’ll save a lot of money if you set up a server at your home or company. You only have to pay for electricity rather than a hosting firm.

A server can consume between 500 and 1,200 watts per hour on average. If you multiply 850 watts per hour by 24 hours in a day, you get 20,400 watts per day, or 20.4 kilowatts per day (kWh). So, for a year, it would cost $731.94 to run the game server on your own.

What is the average amount of electricity used by a server per hour?

Energy consumption is one of the most expensive aspects of any datacenter. While April 22 is Earth Day this year, adopting energy-efficient servers can help you lessen your carbon footprint and save money every day.

Purchasing a server is an investment that will pay off in the long run. It’s not just the cost of hardware and software that matters; it’s also the cost of power to keep that server available to users on a constant basis. When you have a fleet of servers running 24 hours a day in a datacenter, the electricity bills quickly build up.

How is the cost of an electric server calculated?

Let’s say our monthly utility cost is as follows:

  • electricity usage: You use 1000 watts of electricity.
  • The cost of energy is 0.28 cents per kilowatt-hour.
  • The daily usage time is 10 hours.

If we know that, our electric bill calculator will inform us that we’ll use 10 kWh per day, for a total of $1022.70 per year.

Let’s have a look at the math by hand:

  • The power consumed is the total of the power consumption and the time spent using it. As a result, we’ll need 10000 watt hours (or 10 kilowatt hours) of electricity every day.
  • The cost of electricity is calculated as follows: cost = power consumed * energy price. It’s simple: 10 kWh per day multiplied by 0.28/kWh equals 2.8 kWh per day.
  • Simply multiply the daily cost by the number of days in a year to get the annual cost. 2.8 per day multiplied by 365.25 days equals 1022.70. As predicted by the electricity cost calculator (surprised?).

Now that you know how much electricity costs, you might be interested in using the price per amount and discount calculators to save money, or finding out how much charging your car adds to your account.

How much power do data centers consume?

The data center business will require between 196 and 400 terawatt-hours by 2020. (TWh). This is the equivalent of 1% to 2% of global data center energy use per year. Data centers in the European Union alone will require 104 TWh in 2020, according to another study. With the Data Center industry’s expansion on the rise, energy consumption will continue to rise. These facilities can range in size from modest 100-square-foot data centers to hyper-scale 400,000-square-foot data centers with tens of thousands of cabinets. When you use any internet service, you are connecting to one of the millions of servers in one of the thousands of data centers across the world.

What is the power consumption of a Dell server?

Each server was run at 100% CPU utilization. The three Dell PowerEdge R720 servers used about 1,150 watts in total.

What is the reason behind the high cost of servers?

Hardware that can resist the demands of a company is required. These requirements range from ideal program performance, such as processing speeds, to storage demands for large numbers of vital or sensitive data, as well as concurrent user requests. The server hardware that most businesses utilize is designed with a specific function in mind. That is to say, the hardware is more capable of handling the demands of multiple users, demanding storage requirements, and large processing requirements.

Processor (CPU)

Business servers require sufficient processing power to handle multiple users’ requests, run expensive software programs and devices, and manage enormous amounts of data over various connections. All of this necessitates a processor capable of completing these jobs quickly and effectively. Stronger servers are often required by industries that use a lot of intensive software, such as architecture or graphic design, to meet all of their performance demands.

Businesses often have a lot of data, which necessitates a lot of memory on their servers to store it. A business server must have enough memory to meet current and future demands over the server’s lifetime (approximately 3-5 years). Look at how much data your company presently has and how many years it took you to gather it, then use that to estimate how much extra space you’ll need in the next five years.

Hard Drives

Any company’s data backup and storage is crucial. As a safety precaution, most firms require numerous hard drives.

A server with three hard drives, for example, will utilize two of them to copy or “mirror” each other, maintaining an identical record of data that is backed up daily. The third feature is redundancy, which functions as a failsafe in the event that a drive fails. There will be no downtime when the drive is replaced because the redundant disk will continue to work.

Server Operating System (OS)

To establish and maintain network connections with the server, you’ll need a server operating system. It’s also the operating system that communicates with the server computer. Your desktop PC, for example, runs the Windows 10 operating system. You can use this software to interface with your computer. Similarly, in order to communicate with and connect to the other PCs and devices on the network, your server machine requires a server OS.

Client access licenses (CALs) must be installed on each desktop computer on the network in addition to the server OS. Their connection to the server is established as a result of this.

Network Adapters

The majority of servers feature built-in network adapters, however others do not. To build an efficient network connection in these cases, you’ll need to add a separate network adapter card to your server.

Because a server manages many more devices than a desktop computer, it requires a higher power supply (300 Watts). If the server has a lot of hard drives, this figure can go up.

Is it okay to leave your computer on 24 hours a day, 7 days a week?

In general, if you’re going to use it in a few hours, leave it on. You can put it in’sleep’ or ‘hibernate’ mode if you aren’t going to use it until the next day. Nowadays, all device makers conduct thorough tests on computer component life cycles, putting them through more severe cycle testing.
