Thread: 12V from my battery to my computer

Bacause you need 12V clean. Not 13V nor 11V, you need 12V regulated.
And in a car the voltage can go from 8V (while crancking) to 14 ou 15V (while running)

Hello,

Why can't I just take the 12V DC from my battery and stick it in my Cubid computer case.

It has a DC-DC converter inside the case.

Won't that take the input voltage and send it to my motherboard?

Please feel free to make me sound stupid because I haven't even read Electricity...For Dummies.

Thanks

if there is a true DC-DC power supply in there, i suggest you check on the input voltage range for the supply. As shades points out, the votage will range from 8-15 volts. so, if the psu in your computer will accept that range, then you are good to go. if not, you have to have somthing else in there to regulate the power before it gets to the psu.

if you dont have a DC-DC power supply, then you are going to have to look into getting an inverter to convert the DC to AC (like your house) so that you can plug in the computer with the normal AC cord. or you could make/buy a DC-DC supply and replace the one in the computer with the new DC-DC.

hope that helps...
