Is it true that leaving my PC on 24/7 won’t affect its lifespan?
Leaving your PC on 24/7 can have a significant impact on its lifespan. While it’s true that modern computers are designed to withstand constant use, the components can still degrade over time due to the wear and tear of continuous operation. The hard drive, in particular, is prone to mechanical failure when used excessively.
In addition, the power supply unit (PSU) and other components can also suffer from prolonged use, leading to a shorter lifespan. Furthermore, the heat generated by the computer can cause damage to the internal components, especially if the cooling system is not functioning properly. This is why it’s recommended to turn off your PC when not in use to give the components a break and reduce the risk of premature failure.
How much does it really cost to leave my PC on 24/7?
The cost of leaving your PC on 24/7 can add up quickly, especially if you have multiple computers running continuously. On average, a desktop computer consumes around 60-80 watts of power when idle, which may not seem like a lot. However, when you multiply this by the number of hours it’s used, the cost can become substantial. For example, if you leave your PC on for 24 hours a day, that’s around 1.44 kilowatt-hours (kWh) of electricity per day.
Over the course of a year, this can translate to around $130-150 in electricity costs, depending on your location and the cost of electricity in your area. This is a significant expense, especially considering that most of the time, your PC is likely to be idle and not in use.
