That PSU requires regulated 12vDC. Your car doesn't provide regulated 12v.
hi mate. my name is kristian and i am from australia. i was referd to this forum for some help on my carputer setup i have.
i have a gigabyte ga d525 tud atom board with 4gb of ddr3 ram and a 500gb samsung laptop. i cant seam to power the system at all properly. i am using one of these http://cgi.ebay.com.au/ws/eBayISAPI....=STRK:MEWNX:IT.
i can get it in to the car have it running but then it will shut off and then wont restart. i will have to remove the power supply and replace it back in to start it again.
i think that the board thinks theres a brown out of power and shuts it off and puts it in to protection mode. but i am stumped with it i have tryed 2 power supplies, and i think its the varience in the current thats chucking it in to precetion mode.
however i am running a dual battery system in my vehicle so the alternator should keep a charge to the second battery.
if you can help that would be great. my carputer project has been going for months now and i just want to fix this powering issue
But my car has a regulator for a 12 system....
But that is NOT a REGULATED 12V supply which means a voltage regulated to 12V.
That may mean 12V +/-0.1V or +/-0.5V, but not the usual ~12.5V to 14.5V of a 12V vehicle or the typical 8V - 16V range experienced when cranking with old batteries (can be 8V or lower) or initial and transient over-voltages (14.5-16V).
But there are several suitable automotive 12V dc-dc converters (ATX supplies etc) that are purpose built for PC applications. And even I am impressed with their programmable features (and I'm a very fussy Aussie - but I'll leave recommendations for the others hereon with far greater knowledge than me in that area).
BTW - the summary of this reply is "DarquePervert x 2!".
I'm just pre-empting confusion between a regulated 12V supply and a regulated 12V system.
