Built a gaming pc to RUN DIRECT from 12V battery and to have a FANLESS CPU cooler to make it quieter. Showing you the build process and the finished product. Exported the video on this and with Davinci Resolve running and rendering the video it pulled max about 210 watts, and idles at about 105. Although not completely silent, hearing the gpu fans, this is closer to the dream of having a quiet machine and one that works great. On off-grid setup, you usually need to convert battery DC power to AC power then to run to your PC which converts AC power to DC power again that powers your PC components. Eliminated the loss of the inverter in the process and got left with just converting DC to DC electricity. Awesome proof of concept for my brothers and sisters out there in the woods enjoying nature and that wish to have a full desktop for upgradeability and power without sacrificing efficiency, or running an extra inverter. br br This guide was made to help others out there to do something similar and for me to share the passion of tech with the world along with innovative ideas, so that is why I provide tons of links for you to make it all happen.
