Are you worrying that Powering Down your computer every day may cause it to die sooner? There is more to the solution than a simple yes or no.
When personal computers’ boot times were on par with those of nuclear reactors. Shutting them off at the end of the day was often discouraged. That reasoning does not, however, hold true for contemporary PCs with faster CPUs and even faster SSDs that load up very quickly.
Does that imply that turning off your computer at the end of the day is secure? Or would many power cycles prematurely wear it out?
Do Constant Powering Downs Damage Your PC?
In fact, Powering Down your computer at the end of the day puts it under more strain. On the other hand, carefully turning it off doesn’t really cause wear, at the risk of appearing petty. The actual harm, so to speak, happens when you turn on your computer later. Similar to how a car’s internal combustion engine has the highest wear. During starting due to the high amounts of friction produced by the moving parts. A personal computer also experiences startup-related wear.
But does that seem right to you? Except for a few fans and the hard drive. Which is getting harder to find, a contemporary computer has essentially no moving parts. How, therefore, can startup wear occur in a device with solid-state electronics?
That is the result of inrush current. Transformers, inductors, and capacitors included in electronic circuits require large amounts of current to start up. Compared to the power demand during regular operation, this is much higher. All of these parts are found in the power supply unit (PSU) of your computer, with the more recent models (produced in the last 15 years) including Active Power Factor Controller (APFC) capacitors that drain 30A of inrush current.
Much worse, less expensive PSUs with subpar inrush current safety circuits perform even worse. When selecting a PSU for your PC. Using our buying advice is a wonderful method to steer clear of these blunders.
In conclusion, computers do suffer from numerous power cycles. Your PSU, motherboard, and graphics card all experience wear each time you turn on your computer as a result of the capacitors charging. There is no avoiding it, either.
Evening shutdowns are acceptable
Should you just leave your PC running always if shutting it down every day causes wear? Do you also keep your car’s engine running unattended all the time? We sincerely hope so, because even taking into account the wear brought on during starting. It would still be hard to justify the fuel expenses (and carbon monoxide accumulation in your garage!).
The same is true of your own PC. Modern computers are there to survive a staggering 40,000 power cycles, according to the Rocky Mountain Institute’s Home Energy Brief. If things continue that way, a computer that is turn off at night will outlive its owner. Even while repeated power cycles increase the wear and tear on cooling fans and mechanical hard drives, this is not a problem given the typical PC’s five to seven-year service life.
When that happens, you’ll probably update to newer hardware to stay up with modern operating systems, applications, and games. At the end of the day, shutting off your PC is essentially safe. Your electricity expenses significantly rise as a result of the increased power usage brought on by 24/7 operation.
Capacitors Hate Being Run Endlessly
Additionally, keeping your computer on all the time drastically shortens its lifespan. And that’s due to the capacitor, which is a common computer PCB’s weakest link. For the electrolytic kind, the lifespan of these vital voltage control and filtering parts is limited and is normally around 32,000 hours. This is equivalent to a little over 3.5 years.
The usable lifespan of your PC is significantly reduce by operating your computer continuously rather than by using more durable solid capacitors, which last far longer. It is also simpler for computer manufacturers to provide component guarantees proportionate to the underlying capacitor quality since capacitors have a limited lifespan. In reality, the likelihood of a component failing just outside of the warranty period increases with component cost in a system that runs nonstop.
To make matters worse, for every 50°F (10°C) rise in temperature, a capacitor’s useable lifespan is reduce by a factor of two. Additionally, this explains why gaming laptops, which have a propensity to overheat, last less than standard desktop PCs.
Let Your Computer Sleep Instead
What should you do when Powering Down isn’t an option now that we’ve proven that leaving your computer running always is a poor idea? This is valid, for instance, if you want to access your PC remotely. In this situation, it is preferable to configure your computer to go into sleep mode. The RAM is the only component in your system that suspends during this power-saving mode, allowing the RAM to operate at a low power level while reducing the wear on other crucial components.
Additionally, it supports wake-on-LAN protocols, which enable remote access without necessitating a fully powered-on PC. You may even use the hibernation option, which also turns off the power to the RAM modules, to take things a step further. To discover the distinctions between sleep and hibernate modes, we suggest consulting our helpful hibernate mode guide.
In other words, either option allows your PC to enter either low power or total sleep mode, which is ideal for minimizing wear on both moving elements like fans and hard drives as well as for limiting capacitor deterioration.
Both ways Will Be Fine for Your PC
It’s true that a computer that is left on all the time won’t live as long as one that is turned off at the end of the day or is allowed to sleep/hibernate. You are more likely to replace your PC before it experiences a catastrophic failure even in the worst-case situation.
Having said that, wasting electricity on a computer that can be turn off or left in power-saving modes is unfair. It’s safer and preferable to shut off your computer if you don’t have a strong need to keep it on all the time.
Frequently Asked Questions
1. How long can a gaming CPU last?
Regular use seldom results in a CPU failure. The majority of manufacturers provide an of 7 to 10 years before performance starts to degrade. The CPU could keep functioning after 10 years until new technology renders it outdated. A CPU that has been operating for more than 10 years will have a lot of dirt that will block its cooling system.
