Pc save electricity
I gave my father my old computer, and with his older one he would connect the PSU cable whenever he wasn’t using it. Now he’s wondering if removing the PSU cord from the power supply or flipping the electricity switch when not using the PC could cause damage. Also, he’s thinking about saving energy.
It is advised to turn off power entirely when leaving or during electrical storms. Doing so won't harm your electronics.
When the PC is turned off/shut down, it wont consume any power, so removing the PSU cord wont
save
any electricity. Although, as the above user mentioned, its always good to unplug when there's a bad weather condition outside.
There is
no
risk of damaging components when unplugging the power cable, assuming the PC is
fully shut down
beforehand.
Not completely accurate.
In older AT power systems, the power switch functioned as a physical break from AC supply.
For ATX setups, when the computer is connected but powered off, the PSU remains active, supplying a standby load and generating 5V. This signal tells the switch to initiate startup and deliver all necessary voltages.
In newer electronics, this power draw is minimal—possibly under a watt—and USB ports may still supply energy when the machine is off, usually marked with a power icon or distinct color.
When either the power strip or PSU is disconnected, it cannot draw power. For practical use, it's safer to replace a power strip switch than the standard outlets.
It is, but it remains something. The time between failures for components is measured in hours, and regardless of how little work they perform, this MTBE reduces it. On old equipment that isn't used often, it's always a good idea to switch it off.
The savings from turning off a powered-off PC are very small.
Regarding reliability, I suspect the physical act of plugging in or unplugging a power cord could cause more harm.
Unless electricity expenses are extremely high, I wouldn’t even turn off the PC.
Consider using sleep instead of hibernation.
Electricity usage is minimal, and switching on/off takes only a few seconds.
