Low wattage Computer and Desktop

With an interest in solar energy I thought it be wiser to first minimise energy wastage before investing in solar panels. So first on my hit list was my trusty computer. An Intel i7 3770k that was wasting 50 watts (not including monitor) idling at a blank desktop and jumping to 75w when browsing. With my computer on 10 hours a day it was turning over 500 watts of energy into heat.

So I ordered a UDOO INTEL CELERON N3160 Board from here for USD149 (power supply cost extra) and a Hynix 128GB SSD M.2 Solid State Drive for storage at US60

I then installed one of the lightest operating systems on it, Linux Mint Xfce 64 bit, which can be viewed here. In installing Linux Mint I had to set the disks manually because the auto install failed on the UDOO. But I am impressed with the functionality and speed of Linux Mint Xfce.

Interestingly, I haven't notice a great deal of difference in the operating speed of the GUI on UDOO when compared to my GUI (Linux cinnamon) on the I7 when browsing or watching video's. I will still keep my old I7 machine when I need the stronger processor for heavier work (development etc), but for just browsing, the UDOO does everything asked of it.

The UDOO idles at about 6w. And typically only uses a few watts more when browsing or watching video's. It has 12v input so I will be able to run directly from batteries.

By using the UDOO I am saving over 450 watts a day. Not a breathtaking saving by any means but every little bit helps. As a side benefit the little computer is totally silent and looks cute in its acrylic case. There are a number of alternatives including the Intel Celeron N3050 NUC which might prove just as good. I ordered the UDOO X86 because it can also run android 7 if I want to migrate down that path.

That is awesome!

I too have been looking at some lower-wattage options, and have settled on an Intel NUC for those low-wattage duties. I am not quite at a place where I can dispose of my desktop yet, but when I am, the NUC will go to full-time use.

I'm curious, have you found a case for that, or what will you be using to protect it??

Very interesting. Thanks for posting. In a low-wattage environment (like a sailboat or a power outage w/ only a generator) that could come in quite useful. I've converted to all LED bulbs, but I haven't conquered the heat issue yet, which is a killer.

I am surprised at the performance but satisfaction will depend on the operating system you select.

Yes I order an acrylic case for it at $7.90. Its really just two acrylic sheets that covers the top and bottom of the board with a hole at top where the heatsink pops out. I like its nerdy looks but NUC case offers greater protection.

That looks like a promising solution for you, and others. I wrote a dissertation back at university about using stand alone solar grids to power portable, consumer grade devices for sustained periods.. in the 30 watt range... and on a day with poor

Back then solar panels were expensive, not sure what you're set up will be like but using a storage solution like an ultra-capacitor paired with a solar panel (maybe some power management too), you could run that UDOO for long periods and have a fully green solution that will last you for 25 years no problems.

That's a lot of money saved over time, especially as the technology gets better, meaning you'll rely less and less on desktop counterparts.

Slightly off-topic, but I am so proud of my cousin. He installed solar panels on his roof and bought a Tesla. We are waiting for figures, but it is looking good and he may be entirely off the grid. He's 82 years old!

Yes agree, if managed carefully, solar can offer savings. In Australia they allow grid tied systems but charge 30c kilowatt for usage and payback at something like 5-10c kilowatt so its really not that beneficial. I have been toying with the idea of getting a smaller battery system that will be charged by solar panels when the sun is shining and by mains on cloudy days when the battery voltage drops below say 12.5v by buying a suitable 240/120v to 13.5v transformer. So I won't need a huge bank of batteries to cover days of clouds. That will allow me to use all the solar energy that I generate. With the exception of deficiencies in transformers etc when the batteries are being charged by the mains.

So I am planning to setup the computer and monitor on small solar/battery/mains system to see how it fares out.

Good for him. Think it be great to have one less dependency on Government services regardless if it works out cheaper or not.

I was forced to build backup power source for furnace. It showed as a lucky move: now I have one phase 230V in switch board fully backed up and 12V and 5V lines in core of the house. I replaced 10 faulty Made in China power sources with 2 solid invertors 12->12 and 12->5. I generally avoid 9 and 7.5V boxes. 12V LED lights are also connected. Now I have 3h backup for everything I need. Lot of electronics and IT infrastructure runs on 12V internally even if they have AC inlet. I will start with my rackmount switch and connect it directly to my central 12V line. Then I can get rid of standard UPS where 230V is converted to 24V to be converted to 230V (powerfailure) to be converted to 12V for final appliance.

Warning: low voltage equals to higher current, higher current equals to higher current density equals to more heat equals to risk of really nasty fire - especially with large automotive batteries. Use fuses and fat enough wires. Even acid/lead batteries may explode - just two weeks ago it happened in one of our remote server rooms. Acid from 2 460Ah batteries was sprayed everywhere.

Or when not using your computer, you can just put it in sleep mode? I'll stick with my i5 4690K. I rather have hot rod performance whenever I need it XD

Same CPU I feel it is reaching the end of its life though lol
