I'm in the process of getting my Home Assistant environment up and running, and decided to run a test: it turns out that my gaming PC (custom 5800X3D/7900XTX build) uses more power just sitting idle, than both of my storage freezers combined.
Background: In addition to some other things, I bought two "Eightree" brand Zigbee-compatible plugs to see how they fare. One is monitoring the power usage of both freezers on a power strip (don't worry, it's a heavy duty strip meant for this), and the other is measuring the usage of my entire desktop setup (including monitors and the HA server itself, a Lenovo M710q).
After monitoring these for a couple days, I decided that I will shut off my PC unless I'm actively using it. It's not a server, but it does have WOL capability, so if I absolutely need to get into it remotely, it won't be an issue.
Pretty fascinating stuff, and now my wife is completely on board as well; she wants to put a plug on her iMac to see what it draws, as she uses it to hold her cross-stitch files and other things.
You must be pretty young, because back in the dark days of spinning HDDs a computer would take 5+ minutes to boot.
Those days were at worst almost 10 years ago.
Stop living in the past with those situations.
And you get an SSD.
And YOU get an SSD.
And you fine sir also get an SSD!
Suspend != boot
Even in 2010 or earlier waking a pc from suspend would have only taken 2-3 seconds because the whole system state is in RAM not on disk.
At least until MS muddied the waters with "hibernate".
Those were different times.
They are not relevant anymore with current self hosting setups.
