I want to use a Mini-ITX PC board in a car. I plan to use the 12V "cigar" outlet or take the 12V elsewhere, but from the same 12V source that is dedicated to be used for user devices within a car's cabin. How stable is the 12V voltage?
12V regulated, min=1A, max=10A (load dependent). Over-voltage shutdown will occur at ~13-13.5V.
I dont know what that really means... A comment on other site says it needs 12V+-10%. Will I be OK with this power supply?
In case those 12V+-10% is not enough there are of course more expensive PSUs like this one: M3-ATX (125W). It accepts 6-24V input and costs $69. However, I would like to avoid spending extra in case it is not necessary.
