Thread: I'm confused about something ...

Dude the only thing you need is a Opus. www.opussolutions.com Nothing more nothing less. The PSU that Opus sells its absolutely the best. No worrys about anything. It will turn your pc on once it senses 12v on the remote line.

To hook it up its damn easy. It has three wires that connect to your car, and it also includes instructions on how to do it.
Yellow wire - 12v constant, get this voltage directly from the battery
Red wire - 12v remote, get this from your ignition switch, specifically from the accesory line.
Balck wire - is the ground, connect it to the chassis of your car.

edit: Forgot to mention, the Opus also has a jumper that connects to the jumpers on your motherboard for the power switch. This switch is where the lil magic occurs. It will turn ON and OFF your pc.

Dont even think about it twice, best PSU period.

if your using an epia, you could use a 90w

But if you want to expand and add other things to it, there is nothing wrong with the 150w version. If I were you I would order the 150w psu. Always remember the PSU will only put out what the pc needs.

Good lcuk in your install

You could use a cig adapter. But cproaudio's screen fryed and he contributes this to it being wired without a regulator. I'm not so sure, as the screen is rated to withstand a pretty broad range. My screen is wired to a cig lighter, but I like to live on the edge :-)

If you want regulated power, tap into the OPUS PSU. Make yourself an adapter that gets the 12V leads. It should be the side-by-side yellow and black wires on the 4pin molex connector (the one u use to connect HDs/CD-Roms/or even the floppy). I used an old fan adapter to avoid splicing. I plan to switch back to this approach after hearing cproaudio's story. You can chop off the adapter from the ac/dc or pick one up at the shack.

I'm sure this question has been asked before. I think I even asked it once.

Word of caution: Make sure you get the polarity straight or say bye bye to your screen. Positive better be positive and negative better be negative. Stupid install mistakes are not covered under warranty. For $1Million, I will install it for you.

EDIT: Sorry, it was cproaudio's screen not osirisdon's screen.

Robb,

For the record, no one here is going to hate on you. You did exactly the right thing. Posted a specific question in the correct forum. Most new people get chastised for not seaching because the ask the dreaded question:

"I've got a computer and I wanna put it in the car. What do I do?"

You asked a very specific question:

"What power supply would you recommend for an Epia?"

You'll always get answers here if you ask specific questions. Car computing is a very specialized hobby.

How big is the 150w unit any one ? Just a thought will it fit in my ITX case or is it as big a standrd ATX psu ?

Seen the pics on their site but its realy hard to get an idea of how big it is in real life.

Also does it come with the power connector for the ITX systems ?

I though the AT & ITX plugs where diffrent which is why I am asking...

Thanks

Terran
