From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Which distros are energy efficient? I have a capable desktop, and I mean to push it, but I don't want to be using energy if it's not necessary. I'm not looking to rescue an old laptop, for example.

I hear CachyOS is fast. Does that translate to energy efficient?

(Does the OS even matter that much for efficiency?)

Why did you delete the post with system specs, @staircase@programming.dev?

That information would really help people to give you advice and your pc isn’t as unique as you think it is…

Here's the list

  • AMD 9950X
  • Deepcool AK620
  • MSI B850M GAMING PLUS
  • TEAMGROUP 2x32GB DDR5-6000 CL38 Memory
  • KIOXIA EXCERIA PLUS G4 2TB PCIe 5.0 SSD
  • AMD 9060XT 16GB GPU
  • Jonsbo D32 PRO MESH MicroATX Case
  • Corsair SF850 PSU
  • 3x ARCTIC P12 120mm Fan
  • 1x ARCTIC P14 140mm Fan

Probably unplug three of those fans and block off the case openings to get some sort of laminar flow.

Switch to a more efficient power supply. Yours is platinum but it may be worth it to look into a list of low standby power units.

Maybe take out half your ram. It probably doesn’t matter though, I’m thinking about the need for lpddr to get past the 1tb barrier on old servers.

The b850 boards will have efficiency settings in the bios that will make the biggest difference.

Before you change anything though I would recommend first putting a watt meter inline and measuring.

Theres a bunch of stuff you can manually do in software but its fractions of a percent and makes your experience very nonstandard.

The biggest thing is probably gonna be turning off the computer when you’re not using it. It’s not like you’re gonna be spinning down a bunch of hdds…

Thanks but not considering hardware adjustments. I'll look at the bios board efficiency, turning it off, and the wall meter thing
