12900K 'low power' mode? For working from home?

I just had a random thought and I was wondering if it was even possible.
I have a 12900K, 3080TI desktop computer (not laptop) - which I use 9-5 for working from home.

This is light normal tasks such as Outlook, Excel, OneNote etc etc.
Is it possible to somehow set the PC into a lower power state/mode as I don't need this thing chugging along until gaming.

OR - due to me only using these sort of tasks, will it simply use less power anyway?
Thanks!
 
It'll self manage. Just because the frequency might state a set number like 5.2Ghz, doesn't mean it's got a lot of current flowing through it.

The cpu runs quite efficient on it's own.
 
As above it self manages. I have a 12900k, 3090, multiple hard drives (nvme and spinning) and all in all when doing light tasks the whole rig sits at around 100-120 watt mark.

I think most rigs, with desktop class cpus will not be far off. Obviously every pc is different due to other peripherals etc.
 
You can create different power plans even on a desktop system and swap between them - you may need to enable/disable certain options in the BIOS to make most effect and/or to use all power saving features. The savings aren't insignificant if you are only using the high performance plan for periods when gaming, etc. even with modern CPUs which can dynamically manage their power use effectively.
 
Turning off turbo would cap the high power load, but a bit pointless for those kind of tasks, best thing would be to keep an eye on the CPU in task manager to make sure nothing is pegging a core at 100% (like onedrive does sometimes) and clear out any unused apps that are always running.

Removing the 3080 Ti would probably save you more power than any other tuning, but there are options in the BIOS that can shave a few watts. Here's an example for one board: https://gathering.tweakers.net/forum/list_message/72838948#72838948
