Power for Desktop PC??

Former Member

Right now our area is suffering from heavy blackouts and this got me thinking about my desktop computer now rotting away... It is just way to sad and expensive to let it go to waste. So can I power my PC computer via a 12volt car battery without the use of an power inverter?

 

Judging on most of the PC wiring it uses 5volt and 12volt also {negative} -12volt and {negative} -5volt  also there is a 3.3Volt. I included a picture I found on the net to help explain the pins there locations and designation. I hope this helps. I am looking at the ATX 24 Pin connector.  

 

Now I am a complete layman with electronics and have no idea to go about this. That said I know that most cars use onboard computers and even hard drives surely there is enough power to get a gaming computer up and going again?

 

Right now I am using a 700 Watt PSU and it is working really well. But it is no use to me when dead... and running the generator to drive my PC at midnight might be upsetting to others that want some sleep and really a power inverter feels wrong to me as the computer is build to actually use DC not AC and as we know a inverter does consume a lot to function "depending on make and model".

 

So any inexpensive MOD with easy to find parts would be a massive  help.   image

    When I go camping, sometimes I bring my 1KW pure sine gasoline-powered generator.  I can power both my lappy and a projector and speakers with me so that we can watch art film in the evenings.  Yamaha and Honda both make them, mine's blue, so IIRC it's a Honda.  It's small, about the size of a sewing machine.

     

    Still somewhat noisy.  I isolate it with a couple of extension cords intended for electric lawn-mowers.

     

    Sometimes others at the campsite audibly murmur something about my bring tech along with me camping, calling it contradictory or counter-productive or insomniac.  They have never known the thrill of watching a film like Satyricon or Battleship Potemkin when a storm is brewing.  I find turning up the sound a little helps with this.
