    Hey, My name is fernando and i have couple of questions.I have been searching on your forum for some answers and while I have gotten many, there are still some things that I am not sure of. I might have overlooked them over the last 3 days of searching so if thast the case I am sorry.

    I have an old pc which I plan to put in my jeep. I am currently shopping for an lcd screen and an inverter. I know that Pc's take up more power than a regular laptop. Am I going to have to buy another battery if all I am putting in my car is those 3 components?

    Once i start doin the labor, i want to connect my inverter straight to my battery and not the cigarette plug in. How do I go about doing this. I know I have to hook up the wire to the + end and then put a fuse inbetween. However I dont know how to get that wire to power the inverter.

    Because I am unsing and Old Pc, am I going to have to go into the trunk( where i plan on putting it) and pushing the on button every time after I start the car?

    Thank you for your time. I am sorry again if these questions have already been answere but I just havnet found them.

    What are the specs on the old pc?? You shouldn't need to put in another battery unless you plan on using the computer with the car turned off (running only on the battery), otherwise the alternator takes care of that issue.

    Seems like you know how to connect the inverter to the battery, run the wires to the battery, fuse the + lead and connect to the inverter..... for the actually connection to inverter just solder on a cig lighter receptacle on the end of the wires from the battery, or cut the plug off the inveter and just connect the wires (use some connectors so it can be removed if needed).

    For the power button just look on the motherboard and find where the power button connector is now (should already be hooked up if in a normal pc case), and just extend those wires up front and connect to a momentary push button type switch (get it from Radio Shack or something).

          Go here and see how many watts your system would use:

          (Or do a search on google for "Power supply calculator")

          Just from glancing at that one inverter I would think it would be ok if it can supply 400W. If you haven't already I would suggest you check out some of the Power Supply FAQs on the forum here before you go throwing in your desktop and an inverter. I use a small inverter with a mini-itx board but am switching to a DC-DC supply as soon as it gets here, have had some noise/hum issues with an inverter that takes a little work to get rid of.
