This new study, which was published in the journal Energy Efficiency, gives a novel examination of the energy use of gaming PCs…
Today, one billion individuals play digital games all across the world. Gaming is the most energy-intensive usage of desktop computers, and the fastest-growing type of gaming platform is high-performance “racecar” workstations created specifically for this purpose.
We discovered massive performance-normalized variances in power ratings among today’s gaming PC components. For example, central processing units differ by 4.3 times, graphics processing units differ by 5.8 times, power supply units differ by 1.3 times, motherboards differ by 5.0 times, RAM differs by 139.2 times, and displays differ by 11.5 times. Complete systems with low, typical, and high efficiencies that operate similarly correspond to 900, 600, and 300 watts of nameplate power, respectively.
While measured power requirements for most components we examined are significantly lower than nameplateby roughly 50% for whole systemsthe bottom-line energy use is huge when compared to that of conventional personal computers.
We estimate that the typical gaming PC (with display) uses roughly 1400 kilowatt-hours of electricity per year based on our actual measurements of gaming PCs with increasingly more efficient component configurations, as well as market statistics on normal patterns of use. A single standard gaming PC uses the same amount of electricity as ten game consoles, six traditional desktop PCs, or three refrigerators. Running a gaming PC might cost hundreds of dollars each year, depending on local energy pricing.
Despite the fact that gaming PCs account for only 2.5 percent of the global installed personal computing equipment base, our initial scoping estimate suggests that gaming PCs consumed roughly 75 billion kilowatt-hours of electricity per year in 2012, accounting for roughly 20% of all personal desktop, notebook, and console energy usage. To put this in perspective, this equates to nearly $10 billion in annual energy expenditures, or the electrical output of 25 average electric power plants.
Based on market trends and predicted changes in the installed base, we estimate that by 2020, energy consumption will have more than doubled if the current rate of equipment sales continues unabated and efficiency do not improve. Although gaming computers will account for only 10% of all gaming platforms installed globally in 2020, their comparatively high unit energy consumption and long hours of use will result in them accounting for 40% of total gaming energy use.
With high-efficiency components and operations, this considerable energy footprint can be reduced by more than 75% while also enhancing reliability and performance. By 2020, this would equate to a global savings of around 120 billion kilowatt-hours, or $18 billion.
There are currently few laws in place to achieve such improvements, and there is little guidance available to assist consumers in making energy-efficient decisions while purchasing, upgrading, and operating gaming PCs. Product labeling, utility subsidies, and minimum efficiency standards are all potential prospects.
Is it true that a gaming pc consumes a lot of power?
A gaming PC’s typical annual energy consumption is roughly 1,400 kWh. This is equivalent to the power used by ten gaming consoles or six standard computers.
Is a computer responsible for a high electricity bill?
Running a gaming PC 24/7 with an energy consumption of 400W per hour will cost $38,19 based on the average US price of 13,26 cents per kilowatt hour (kWh). A system that consumes 600W per hour, on the other hand, will cost $57,28 per month.
Here’s a rundown of systems that consume various watts per hour and how much they’d cost if left on 24 hours a day, seven days a week:
As you can see, gaming PCs can be pretty costly; nevertheless, the majority of systems are priced in the $400W-600W range, with monthly costs ranging from $38,19 to $57,28.
Because energy prices vary by state and country, the figures above can fluctuate significantly depending on where you live. For example, if you live in Louisiana, where the lowest per-kWh rate is 9.34 cents, a 600W system would cost $40,35 instead of $57,28. (saving of 29,56 percent ).
Is gaming associated with a higher electricity bill?
The amount of energy your typical PC consumes is determined by a number of factors, including its hardware, installed software, and how frequently you use it.
A PC that is continuously on and mining cryptocurrencies, for example, will use more power than one that is just turned on once a day and used for browsing or reading emails.
Meanwhile, a PC outfitted with energy-saving components and settings consumes less power without sacrificing performance.
For example, a computer with a 10TB hard disk drive (HDD) consumes up to four times the amount of power as one with an equal-sized solid-state drive (SSD).
Similarly, more RAM, more processors, an integrated video card, and a lower-frequency graphics card lessen the amount of power used by your PC.
One of the most energy-intensive applications of PCs is gaming. Your gaming PC, according to this MakeUseOf article, has more advanced hardware than a conventional PC.
A gaming PC, for example, usually has a more powerful GPU, which consumes more electricity to run. As a result, its energy consumption is greatly increased.
Keeping this in mind, a typical gaming PC takes 300 to 500 Watts of power. When playing VR games, this usage skyrockets, reaching 600 Watts or more.
How much does it cost to keep a gaming PC running 24 hours a day, 7 days a week?
For the example equation below, we’ll use an average of 13.3 cents per KW/h and a 24-hour runtime. In the tables below, we’ve split that down into eight and four hours every day. 5.180.62 cents per KW/h * 0.541 KW * 720 * 13.3 cents per KW/h = $51.81 per month! Monthly cost of running a PC (24 hours/day) if
How much does it cost per hour to run a gaming PC?
Using Outervision’s power supply calculator and our recommended setups from our PC construction instructions, let’s see how the power requirements compare between different levels of performance. Then we may manually compute the cost of electricity per hour in the United States. Because we’re talking about gaming builds, all estimates will take into account a gaming keyboard and mouse, as well as the resulting load draw.
When we compare the four designs, it’s clear that a more powerful processor and video card increase the system’s power usage dramatically. Also, none of these estimates take overclocking into account, which is why each build has a lot of headroom. It also does not scale evenly across platforms. The 8100 isn’t capable of being overclocked in the budget configuration, and overclocking the 7900X in the extreme build has a significant influence on load watts. Extra headroom not only keeps your system safe during overclocking, but it also provides for future growth, which is important to remember if you don’t want to spend money on a new PSU along with your improvements.
But what about the cost of maintaining these systems? If you know the cost per kilowatt hour (kWH) and the system power usage, we can figure it out with some basic math. Choose Energy is a wonderful resource for viewing power rates across the United States if you don’t know your rate or don’t have access to your electric bill. You can also compare prices between states and see the national average cost, which we’ll use in our comparison.
In the United States, the average cost of electricity is 13 cents per kWh, which means it costs 13 cents to power something that uses 1000 watts for one hour. Divide the watt usage by 1000 and multiply the result by your kWh to compute the cost of running your PC at full load for one hour. If you game on a PC that utilizes 300 watts, an hour of gaming will cost you little under 4 cents.
Even the largest cost difference appears insignificant when viewed on an hourly basis. However, if we multiply that by two hours every day for a year, it can start to mount up. The cheap build will set you back 29 dollars each year, while the extreme build would set you back 77 dollars per year, about doubling the amount. When overclocking is taken into account, the cost difference becomes much more considerable.
How much does it cost to power a computer?
According to Michael Bluejay, commonly known as Mr. Electricity, the cost of running a computer ranges from $631 to $5.50 each year.
Even Mr. Electricity acknowledges that’s a big range. For a Windows desktop PC with an LCD monitor and sleep mode activated, a typical annual energy bill is less than $10.
The free Joulemeter tool from Microsoft helps you calculate how much power a Windows desktop or laptop consumes. When measuring a desktop’s energy consumption, Joulemeter’s developers intend for the program to be used in conjunction with an external power meter, though the program’s Manual Entry option generates an approximate power-usage number; the energy use of laptops is determined without the use of an external power meter.
A WattsUp Pro power meter is necessary for precise calculations of desktop power consumption, according to the Joulemeter user handbook. On the vendor’s website, WattsUpmeters range in price from $96 to $196.
The program also calculates how much energy each presently running application consumes. Click the Start button after typing the name of the program’s executable file (for example, “firefox.exe”) in the text box under Application Power on the Power Usage tab. The current readings can also be saved to a file for future reference.
When I used Joulemeter’s manual approach to estimate the energy consumption of two Windows 7 desktops and a Windows 8.1 laptop, the application said the desktops used roughly 75 watts per hour and the laptop used about 25 watts per hour. Our household’s computer energy cost is in the neighborhood of $1 a month, because our local power company charges an average of slightly over 15 cents per kilowatt hour.
This sum, of course, excludes the cost of charging our two iPhones and three tablets. Outlier’s Barry Fischer estimated the cost of charging an iPhone 5 and a Galaxy S3 for a year at 41 cents and 53 cents, respectively, in September 2012. Don Reisinger wrote in a June 2012 post that an
How much power does a computer consume?
If you’ve ever wondered, “How much electricity does a computer use?” we’re afraid there isn’t a straightforward answer. Having said that, we’ll do our best to answer the question here.
Most computers are designed to take up to 400 kilowatts per hour of electricity, but they typically use less.
The average CPU consumes about the same amount of energy per hour as a standard light bulb. A computer with a Pentium-type CPU consumes roughly 100 kWh. With the monitor turned off, this is how it looks. The monitor on your computer usually consumes more power than the processor.
When you turn on your monitor, the amount of electricity used increases. Different computers will consume various amounts of energy. Speakers, printers, displays, and other forms of devices will all require power to operate. Connecting these devices to your computer will also require energy. All of this will have an impact on your electricity usage.
When you launch an application and begin working on your computer or laptop, the same thing happens. Depending on the program you’re using, the amount of electricity your computer consumes will vary. A word processing program, for example, uses less electricity than a computer game. Downloading, uploading, and streaming files will all use more energy than reading a pdf file or doing something else text-based.
As you can see, there are a plethora of reasons why your electricity usage fluctuates. Because of these variables, determining how much electricity your computer consumes is impossible.
Examine the maximum electric capacity of your equipment. That information can be found in the user manuals, on the box your device came in, or by doing a fast Google search. After you’ve totaled those numbers up, calculate the average cost of a kilowatt-hour in your state. These figures will differ from city to city, but the state average will provide you with a reasonable estimate of utilization. Multiply the kilowatt usage by that cost once you have the average cost for your state. This will calculate how much it costs to run your computer for one hour. This final illustration presupposes that your PC is being tested.
Most of the time, you don’t expect much from your computer. It’s most likely powered by electricity, therefore it’ll cost you a lot less than you think. But at the very least, you know how much it will cost.
You may even multiply it by the projected number of hours you use it each day to get an estimate of how much electricity you use on a daily basis.
You can figure out your electricity usage better than we can if you do some research.
How can I lower my PC’s power consumption when gaming?
Every month, I dread the day when the mailman delivers the bills, and the energy one is the one I dread the most. This is the one that regularly drained my bank account, so I began looking for ways to lower my home’s power consumption. Apart from the typical suspects such as the refrigerator, microwave, television, and so on, my computer is the biggest power hog.
How to Reduce Power Consumption on Your PC
We all know how much electricity PCs consume, especially if you have a gaming or multimedia station. These can have a significant impact on your electricity bill, but don’t worry; there are methods to save money. If you’re concerned that your computer is consuming too much power, try some of these easy ways to save money on your electricity bill. I’ll try to discuss the best approaches, and there are three primary categories to consider:
We’ll start by looking at how you can lower your PC’s power consumption by changing your hardware and how you use it. I realize some of these are counterintuitive, but stick with me and give them a shot. Some of you may wonder how that is feasible. I’ll go over each component that consumes a lot of power and show you how to make it work with less.
CPU (Central Processing Unit)
Your computer’s “brain.” This is a massive power user, consuming an average of 100W. (up to 150W in some high end CPUs). There are a few techniques you can take to cut down on this energy hog.
Yes, you are accurate. Some modern CPU models have improved power management capabilities that allow them to use less power, and having a better CPU also means more performance. It is beneficial to have a larger number of cores. First and foremost, the performance will vastly improve. The most significant point is that if you have more cores, your load management will suffer.
For example, if a single core CPU is running at full speed (100 percent), it will consume a significant amount of electricity. If you have a quad core CPU (4 cores), each core only functions at 25% of its maximum capacity, so there you have it. Your CPU will run under 25% load, which implies lower temperatures, longer CPU life, and less power consumption.
According to your CPU maker, open your BIOS menu, CPU settings, and discover the power options:
- ACPI (Advanced Configuration and Power Interface) has two options: S1, which stands for “Sleep,” and S3, which represents for “Hibernate.”
If you have access to these functions, you should turn them on to improve power management. They control how much power the CPU utilizes based on the lead it has. The lower the temperature, the less the cooling have to work, and so the CPU saves power.
Overvoltage, on the other hand, refers to an increase in your CPU’s VCore (or Core Voltage). In the CPU settings, you must reduce the value of VCore. An undervoltage occurs when the voltage is reduced below the default value. If your CPU operates at 2.375V, an undervoltage would reduce it to 1.965V or even lower. However, when changing your computer’s voltages, be cautious. Although there isn’t much harm you can do, there is a chance of instability (this is the BSOD – Blue Screen of Death, for those who don’t know what I’m talking about).
A BSOD is harmless in and of itself; it just indicates that there is an issue with your machine. So, after making any changes to your BIOS settings, I recommend running a stability test (with benchmark programs such as OCCT, SuperPI, Prime95 etc). These are the primary methods for conserving CPU power. However, bear in mind that if you want to overclock or benchmark your PC, you may notice a tiny performance drop.
Larger RAM Memory, like the CPU, is better for your computer’s performance as well as power efficiency. Your computer saves instructions that it uses frequently in RAM memory. So having more memory to store more instructions is preferable to wiping and rewriting them.
This will save a few Watts of power while also improving the performance of your computer. You should also be cautious about how much RAM you utilize on your computer. More RAM will reduce the space available on your HDD (Hard Disk Drive) under Hibernation Mode, as I shall explain later. However, if you are unconcerned about this, go with at least 4 GB of DDR RAM (I would recommend from 8-16 GB DDR3). Learn more about our PC purchase guide to see which options are ideal for you.
Bigger and Better HDD
Probably the most illogical of the bunch so far. How does a larger HDD save energy? When you understand how a hard disk drive works, the solution is straightforward. If you’ve ever opened one, you’ll notice that it resembles an old record player. It consists of metal disks with a reading head that goes up and down the disks to locate the information required. Another thing to keep in mind is that the information is not contained in a single location, but rather is dispersed across the disk’s whole surface (in tiny fragments).
As a result, the reading head must move across the full occupied surface of the disk in order to retrieve that information. Let’s pretend I have a 500GB hard drive. My hard drive is full, and I’d like to view a movie. The HDD’s reading head must put together the entire movie from the disk’s entire surface. That implies it needs to read the information and find my video by moving up and down the entire disk. Assume I wish to watch the same movie on a 1TB hard drive. Because the HDD is only half full at 500GB, the reading head only has to traverse 50 percent of the way around the disk to find the same information. That is half the distance it must travel, resulting in decreased energy use.
Of course, there are other options for dealing with the HDD issue, such as employing a RAID arrangement. For those unfamiliar with RAID, it is the practice of storing the same data on two or more identical HDDs. This will significantly boost the speed of your computer, implying that the disks will work for shorter periods of time and hence consume less power.
I’ll also mention another technique to save your files in the Hard Drive section that can save you money in the long run: SSD (Solid State Drives). So far, these are the fastest drives. They have no moving parts, run at breakneck speeds compared to HDDs, are completely silent, and consume a fraction of the power that a typical HDD consumes, thanks to the absence of sophisticated mechanical mechanisms in favor of integrated circuits.
The only disadvantage of SSDs is their high cost. They are substantially more expensive than HDDs and have much smaller capacities (32-256 GB, but there are a few that go up to 1.2 TB, but they cost a lot). But consider this: if you don’t have a lot of files on your computer and solely use it for web browsing and email, a 64GB SSD would be ideal. Top-of-the-line performance at a fraction of the cost of electricity.
