i plan on going SFF for a computer in my car. how big a PSU do you think i'll need for this list?

VIA EPIA Nehemiah M10000 1Ghz
512MB DDR
80Gb 5200 HD
802.11g WIFI
DVD-Rom
USB GPS reciever (DeLorme Earthmate)

will a 90w PSU will supply enough power?
 
no way 90 will be enough. I'm pretty sure you will need at least 200 watts for all that stuff.
 
i disagree, he does not need at least 200watts, most sff systems are fully loaded running off stock 200w psus or less

I dont know if 90 is enough, but if not, one of those ~140W matx psus

my crappy guestimate:
VIA EPIA Nehemiah M10000 1Ghz -40 watts (maby too high for this in particular? NO IDEA)
512MB DDR - 10 watts
80Gb 5200 HD -20 watts
802.11g WIFI -10 watts
DVD-Rom - 15 watts
USB GPS reciever (DeLorme Earthmate) - 10 watts

haha, but I really have no idea how much these things all draw

best bet is to google what other people with car rigs use with a similar setup

well if my specs are close to what you said then i should be fine with a 150W one then. I might get a 200w one just in case.
 
Why dont you just get one of those DC-DC ready power supplies designed just for Carputer setups. I forget the company name, some guy on general mayhem was actually selling a complete carputer setup with that psu.
