Thread: MY CARpute setup need some INPUT from YOU!

To be totally honest. GO WITH THE OPUS. You will waste more money getting a bad power setup than going straight for an Opus.

Power is the one thing people overlook, but it is the most important thing.


You won't regret getting an Opus.

like i said, i know people would say OPUS. but for now, this is what my pocket can afford.

any answers to the other questions?

No offence, but people will say Opus because Opus is the best you can get.

Your pocket will like you MUCH better if you save the $70 or whatever you're spending on the Morex and ITPS and put that towards an Opus, rather than spending that, PLUS the extra $$ on an Opus when you find that the others don't work as well as you want.

Believe me, i've been there, and I am regretting not getting an Opus straight off.

The cheapest way to do a Carputer setup is the right way.


If, however, you don't take my experience from putting myself out of pocket, and decide to waste your money on the Morex/ITPS, then yes, in theory you can just connect them to the battery, through a fused wire. I would however connect the +12V for the screen into the power supply for a much cleaner signal (of course this is going on your use the Opus which is regulated)

what's going to be the downside of my setup (morex 60w+ ITPS) as to OPUS?im going for the morex+ITPS because the case i got came with the MOreex 60w already... but thanks for the suggestion. eventually il go for the OPUS

Downsides with the ITPS as far as I can see:
- computer will lose power when starting the engine (cranking)
- computer may not run while the engine is off
- fewer devices: ITPS and Morex have a 60W max, Opus is 90-150W

You probably won't be able to power the external DVD drive off the ITPS+Morex. Search for power calculator or power simulator to get an idea of your power requirements. I believe full size CDROMs consume a lot of power.

Geez, this is a common theme here, I'm glad people are asking though instead of wasting money. Here's the deal: the ITPS/morex deal will probably work for your computer, the external DVD drive will have to run off an inverter. The computer will not survive cranking but if you use the ITPS the way it's supposed to be used, you computer won't turn on until after you are done cranking anyway. The computer will not work while the car is off. Check the power calculator at www.mini-box.com to see what you'll be limited to as far as power. I know these things because I've hand built an ITPS using the original schematics and I've tested the three I built extensively.

Sorry to drift off topic like this but... I see your in meda AZ. so your no stranger to heat
How do you deal with heat and the carputer? Has it been a problem for you?

Thanks,
Chris

Well... I have yet to actually deal with the heat to be honest. My computer is not in the car yet. However, I have prepared of it. I'm using a case from www.clearpc.ca to house my VIA board, the board is already cooler than most, the case has two 80mm fans (in and out) and the board stands about 1/2 an inch off the side of the case. The case also has alot of extra room in it, it's not a cramped little thing. The computer will sit in my trunk which is generally cooler than the greenhouse of a passenger compartment. The case has alot of air going in and out of it. With temperatures around 120F though, we'll see this summer. I'll let you know. We'll start a new forum for heat management. ha. My desktop has a 120mm fan running full tilt if that gives you any indication.

I wanted to check out that case, but is the site down? Wrong URL?
