How to use less power while PC is on 24/7? [closed]

I've done the thing you're asking.

You need to create a new powerscheme and put everything on low etc, including turning off the screen. I did this to mine bitcoins on a laptop when I closed the lid and resume normally when I opened the lid. The system went from 120 Watt usage to 15 watt usage, or something similar.

You don't mention what OS you are using, so I will assume Windows 10 here.

Right-click the start menu and select Power Options

On the left, click Create a power plan

Select Power saver and name your new plan something like Ultra low energy

Set Turn off the display to 1 minute, and put the pc to sleep, to never.

Then press Create

Next, click Change plan settings on the right of your new powerplan.

Click on Change advanced power settings Set everything relevant to as low as possible, but the most important settings is the following one (it will have significant impact on power reserve and system performance)

Unvold Processor Power management Set the following: - Minimum Processor State: 0% - Maximum Processor State: 5% (you can set this to 1%) but if your system is not that fast, it may crash. 5% is a safe setting that will already safe lots of power.

If your computer uses wireless, You will want to change it to maximum power savings, though using a lan cable and disablign wireless will of course be more effective.

With this new power scheme in place, the laptop will work really slow, but it will also not consume much power.

Want your system back to speed, change the powerscheme.

There are programs to change between powerschemes and it is possible to use powercfg commandline options to switch different schemes.

With the powercfg commandline option, it is even possible to use Scheduled Tasks to make the computer go into extreme power savings mode at 23:00 and get back to normal operations at 7:00.

You ask a complex question without providing enough information (OS, purpose, hardware particulars) to provide an accurate answer.

There is most likely no single thing you can do to fix the problem - it is a matter of finding what draws the most power and reducing - repeat until satisfied or out of options.
