Computer W/23.8" Display 10 Watts

[Papa]

I'm off-grid. I upgraded to a newer computer with a larger 23.8" display. Clearly, it is NOT a gaming machine, but primarily does CAD and internet. As the image shows, it is pulling 10 watts from my inverter via the OEM 65W power supply.

There are a great number of power saving settings, both in the bios and in the OS.
Do look those up.

The Power bricks that come with notebooks aren't known for their efficiency either.
If you're off grid you might look at waht DC voltage is supplied bt the notebook itself.
If it's the same as (or close to) what you supply to your LED light say; you might skip the whole:
DC to HC AC to LV DC again, saving on that inefficiency.

The BIOS on the above AIO doesn't allow core changes, and little else

I do NOT typically run through psu's when I have the correct DC supply voltage(s) directly from batteries. The above AIO setup was only a test to compare with/without PSU under load.

Matters not now anyway, I've upgraded to 27" 4k thanks to LG's closeout @ $170. Then turned around and bought a Ryzen 7 Mini to feed it. BIOS on it allows 15w, 25w, 35w user selectable. Both the monitor and the mini are 19vdc powered and draw about 18W combined (watching 4k YouTube vids) so I'm not overly disappointed. That's through Manjaro, Which isn't the most efficient OS (even with all the tweaks)

Is the screen one of those 12v DC screens I've been looking at?
I ask out of interest as I've gone and got myself stuck in the 'New South Africa' where electricity is more off than on.

I am looking/hoping at going Solar here.
I will be changing the lighting circuit/s to 12V DC and LEDs powered by a battery charger and a bunch of paralleled car batteries (or similar) as an initial, keep the dark at bay, step.

This system is an old AMD A8-6600K (Richland), 8GB with Linux Mint on a 'broken' Samsung 960 Evo SSD I 'fixed' = free.
(+ HDDs for movies etc)

It's not nearly as efficient as the new Ryzens, but does the job of surfing the net etc and as a 'TV Box'.
It's a bit of a power hog at over a 100 watts for the APU alone so still debating as to whether I can/will downclock and undervolt and put that on the circuit with something like this:

I read that Linux is a little more power hungry than WindBlows.
I find that strange considering all the extra crap that WindBlows runs..?
Personally; I don't care! 69ing a rabid skunk on the podium of a Syrian mosque is preferable to WindBlows!

My router already has a battery backup.
