Is keeping your PC on 24/7 a convenience or risk? At My Computer Works, we’re often asked this question repeatedly. Whether you’re a gamer powering demanding rigs, a creative professional who needs constant remote access, or an average consumer simply desiring immediate startup, it’s a good idea to learn if it’s okay to keep your PC running 24/7
In our latest blog, the team at My Computer Works explores whether keeping your PC on all the time is doing more harm than good. Spoiler alert: it depends. So, with this in mind, let’s dive in!
How long can a PC run continuously? Theoretically, contemporary computers can run continuously for years or even several years.
Yet mechanical components like fans and hard drives wear out slowly over time. Fans rotating at thousands of revolutions per minute accumulate dust and slow airflow, and rotating platters in HDDs sometimes lock or make clicking noises. More resilient SSDs also have a limited number of write cycles, and continuous background reading and writing will eventually reduce their decades-long lifespan.
Power Supply Units (PSUs) also undergo stress due to heat and load variations. Excessive heat can cause capacitors and other components to degrade and fail prematurely. Considering this, keeping your PC on 24/7 is not the best idea if you want it to enjoy a lengthy lifespan.
However, if you decide to keep it on all the time, to counteract these risks, make sure your casing has adequate airflow, change dusty filters periodically, and look into acquiring good-quality cooling solutions. You might also want to invest in professional computer servicing and maintenance with My Computer Works.
Besides wear and tear, is it economical to keep your PC running 24/7? A typical desktop uses between 60 W at idle and up to 300 W under load. Running that 24 hours a day translates into 43 to 216 kWh per month. Since you’re looking at an average electricity rate of at least $0.13 per kWh, you’re looking at $5.59 to $28.08 monthly just to keep the power flowing.
A better alternative to saving on costs is to use Sleep Mode or enter a full shutdown. Sleep mode generally consumes less than 5 W, reducing consumption by more than 90%. Shutting down completely drops power to almost zero, although some motherboards will draw a trickle to maintain features such as Wake-on-LAN.

Keeping your machine on can guarantee that system updates download and are installed when it’s not in use. It can also run background processes such as antivirus scans or defragmentation (for hard drives) without disrupting you. For this reason, servers and remote workstations tend to remain on permanently and work well, albeit with a reduced lifespan.
Unfortunately, without regular restarts, system software can experience memory leaks, where processes will not relinquish RAM. Also, resources dwindle over time, and you’ll see slowdowns, crashing apps, or system crashes. The solution may be daily or weekly scheduled restarts, depending on what you’re doing.
There are specific reasons behind keeping a PC on 24/7. Here is when it makes sense to do so:
In addition, network drives, virtual desktops, and cloud-supported services tend to necessitate keeping machines up and running.
So, if you’re just surfing the web and exchanging emails, ask yourself, “Should I turn my computer off at night?” to save energy and decrease wear and tear. How you answer this question will help you make this decision.
Here are some tips on how to monitor PC health and improve performance, longevity, and efficiency:
Ultimately, it depends on your own requirements. If you depend on continuous availability, scheduled operations, or remote access, keeping your PC 24/7 can be a good idea, assuming you implement energy-efficient PC settings, keep your hardware in good shape, and carry out regular shutdowns.
If you don’t require immediate availability very often, shutting down overnight or employing sleep mode will preserve component longevity and reduce your energy bill. So, are you ready to improve your PC’s performance and longevity and learn more about the pros and cons of keeping a PC on 24/7?
