    Should I ditch my Opus 150 for my CF-bases system?

    Hey guys

    I have migrated to a compact flash based system because of extreme temperatures here.

    I have an Opus 150 that I'm using to power the system. However, I no longer need a "safe" shutdown because NO WRITES are being made to the Compact Flash card due to the way I've set up my XP "embedded" install. All I need is a HARD shut down when the ACC (switched) power line is off. I do still need my system to receive on "on" pulse when the ACC line receives power.

    I'm using enough hardware that I need about 150W of power.

    What is the best way of accomplishing this? Should I ditch my Opus and try a different powering method or should I keep the Opus? It seems to me that the Opus may be overkill for my application now.

    whats wrong with overkill.... theres no waste really that I can see....I'm still using my opus 150 in my laptop install....sure I wouldn't have bought it specificaly for this aplication, but I see no harm in keeping it.....

    I guess that's why I'm posting this...it is overkill, but it doesn't really hurt much.

    The only thing that bugs me about the Opus is that it doesn't turn off for the default 3 minutes after the ACC power line is off. I would like the Opus to totally cut power once the ACC line is off. Any suggestions?

    since you don't care about the hard shutdown, you could wire a relay interupt between the motherboard & 12v feed....turn off key-bang instant off.....turn on key...12v circuit connects & then opus boots system.....but what if you want to just restart the car.... what if you just want to turn back to acesssory without dropping the computer dead... I would leave the delay.....
