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.

Is this really true? Modern components have fairly robust power saving capabilities. Just because it's got a 750W power supply doesn't mean it's drawing 750W all the time.
My gaming PC takes 250w while gaming, my diy mini pc daily driver desktop takes 40w while working, my mini pc server running proxmox takes about 15w on average. The difference is over 10x in my case.
I said at idle.
Yes, it's really true.
It's not really 10x unless you're comparing to something like an N100 mini PC. It's not unusual for a gaming PC to idle around 100 watts though. That does get expensive if it's on 24/7.
Yeah, a sff mini pc draws below 10 W on idle, so the math is about right, even if a gaming PC can also draw as low as 40 Watt on idle if you buy a reasonably powered gpu.
I assume most people running a dedicated personal server are using that or something similar. In the case of RPi or similar SBC it will be even more.
