its sitting on a table without a case and rigged 4pin wires and atx connectors since the m2-atx doesnt come with all the parts.

this thing rocks! i have it running on a 7ah sla battery, it runs for about an hour while playing video off the wireless internet. i think it pulls about 80w total strong load, though my meter isnt working right now so i cant tell for sure- im just guessing by the battery life.
i can play milkdrop visualization, it works much better then i thought it would... i cant wait to install this in my car
hey, it may not be in a car but at least its running off a battery! and yes, it made the install before it died
btw- please someone stop me from throwing a smart charger at 10a on there for an attempt at continuous usage. i want to upload a bunch of media to this machine but i dont want to hurt the power supply or pc... i cant imagine it would be good to use a car battery charger as a 12v source....
Have you thought of using a house powered PSU?
Nevertheless, I think you will be ok with the charger and a known good car battery. Charge it for a couple hours then do your thing before you drop below 12 volts. My carputer system is now pulling 5amps off the charger while I respond to you.
It looks like you're running very close to getting a blue screen or shut down. Charge it up quick!!
oh no, that m2-atx can actually run down to 6v and still kick out. at first though, i did not set the power supply right and it did not have the low-voltage shutoff, so i watched my battery hit 10.5v then it started to plummet fast, about .1v every second. i took it off quickly, of course then my pc was dead but it still ran even at 10.2v
after sleeping on it i think youre right, there shouldnt be much of a problem running the pc off the charger, so long as the battery is still hooked up (act like a capacitor).
oh yeah, i had a 150w house atx supply for the 12v feed, but after 1min of use it went down to 11v and would not even power up the pc pos emachines gear haha
Nice job on the new carPC setup. Would enjoy seeing some pics of it in the car.
I just did not have the time or energy to work with a dc-dc psu, so I installed a desktop PC in my Saturn wagon, usins a Vector inverter. Has been working verrry satisfactorily for one year now. I just have to remember to shut down the inverter whenever I exit the car, but have become trined to do that...
Best of luck and blessings on yr carPC endeavor. It's a lot of fun.
hey thats good info bruce, thats what i was going to do at first. but the power supply was an xmas gift- nothing like sending out an email list with hotlinks right to your items
i can also conclude that running a car charger on the small battery while the pc is running seems ok too. i ran it all day, no burnt house and pc is still kickin great.
more surprisingly, the charger was only set to 2 amps and the battery still charged. so, with all the speedstepping or whatever this board/cpu does it helps tremendously. at idle this pc consumes less then 24w. this is exciting because ill certainly be able to leave the usb devices on for a long time, like days, without any problems... and also that means i should be able to have wake-on-lan ready and working while the car is parked.
im so glad i went the matx route and not some itx crap stuffed into a small case that easily stolen. if anyone does find my carpc, it will be in a rat's nest of wires and **** stuffed behind a seat. nobody will even want to touch it when i put the electrical hazard stickers on there hahaha lol
ps- will i always have to take as much grief from everyone when i explain to them my newest project? i get nothing but laughs when i say im putting a computer in my car. "hahaha why?" is what they say... i reply 'music, gps and obdII mainly' and they say "yeah but thats crazy to put a whole computer in a car". whatever. when i get it done i can pull up to them, watch them fumble around with their ipod while i flick on music, fire up the gps and actually get to my destination with comfort to spare
i should have taken a picture... my charger was off and i forgot... and my voltmeter wasnt turned on either.
i realized this and flicked on the voltmeter.... 5.4v!!! pc was still running fine. its charging now... 8.5v and rising fast haha.
pretty impressive to run a pc off 5v. hope i didnt hurt anything.
Many people laugh at the idea, but once they see it the "wow" factor kicks in.
i know how much i like it thats for sure. im regularly in my car trying to do something and just thinking 'you know, a small computer would do this perfect right now' and i swear the list is in the hundreds of uses...
