Which power supply
After reading the forum for a while and reaching a dead end.
This is my first carputer so please bare with my ignorance
System :
zotac dual atom 330 ION motherboard
4 GB RAM
500 GB 2.5 HDD
LCD:
liliput eby701

what im looking for is the right dc-dc regulator that can handle the above mentioned and power the bunch of usb & serial devices to be thrown on it
currently im looking at the carnetix 2140 , opus 320 or the DSATX or are they an overkill for such a setup ?

I would really value your opinions

The Carnetix units aren't well-suited to your motherboard.

The DSATX or high-end Opus would work fine with that setup, but they are overkill, especially with the low-power Atom/ION board.

i think that a m2-m3 should power it, but i am using a similar setup with a dsatx, and love it--no problems like the m series, and i figure that i have more reserve power before i need to worry about overloading the power supply.

i beleive that the carnetix unit is for regulated power, and is not atx compliant(though i could be wrong) the dsatx has worked flawlessly in my setup, the only thing i don't like is the serial interface (i wish it was usb, and had a easy to use GUI). but so far, i have been able to get it to do everything i need without ever using the serial interface
