FAQ/ Newbies guide to Power supplies.
Okay so just what are the issues that need to be considered here?
Normal PC all you have to worry about is will your PSU kick out enough current at the various voltages to keep all your random bits of kit running.
With a carputer things are more complicated. I know there's the voltage srop when the starter motor fires your engine up and all sorts of other messy voltage drops/spikes to deal with.
Then there's the issue of running out of battery power and having the thing go flat on you. People have suggested all sorts for this like shutting the carputer down or auto switching to a backup.
Which PSUs offer what options for these?
Are there more complications I've missed?
At the risk of starting a holy war is there a clear 'best' PSU out there at the moment?
