I have a casetronics case, morex 80w power supply car kit, epia mii-10000, 515 mb ram, no cd, itps, 160 gb hd that i am having trouble with. I have seen the ITPS is not getting great reviews these day (like it did when i bought it). Im having power trouble currently so what is reccomened to upgrade to? one thing i did like about the itps is not being able to run computer while the car was not fully on.

Yes, it will power the computer while the car is off. When you remove the key, it will shut the computer down.
You will be able to reuse your morex 80. Basically, the 1280 will replace your ITPS and gets hooked up very similarly. They have the instruction manual online if you want to look at it to see how it works.
I have done some further investingation with my multi-meter reader and have got the following findings:
Engine running (computer turned on)…
Battery terminal: 14.15 volts
Before Itps: 14.15 volts
After Itps: 12.01 volts
Engine not running (computer turned on)…
Battery terminal: 12.25 volts
Before Itps: 11.5 volts
After Itps” 10.5 volts
Hard drive within computer begins beeping: 10.0 volts
Engine not running (computer turned off)…
Battery terminal: 12.25 volts
Before Itps: 12.25 volts
After Itps: 12.25 volts (did not gauge have to assume)
These are my findings, any suggestion as to how i should go about fixing the problem so that i dont have to have the engine running in order to keep my computer on...Remember its my hard disk that's complaining by beeping.
Good investigation. As you see, the ITPS drops your voltage by about 1.5. This is the problem that will cause you endless headaches. It will cause your hard drive to freeze and shred your install, requiring a reformat and reloading of your operating system. (Well, at least that's what happened to me and I had similar readings as you).
The easiest thing to do is to replace your ITPS with a higher qualilty regulator. I chose the Carnetix and it fixed the problem. There are other options such as Opus, or CarPC, etc.
There is another way - you can hook a relay to your system that closes when you turn off the power, bypassing the ITPS. I've seen a thread about this awhile ago. You'd have to figure out how to trigger the shutdown sequence, though. Perhaps a DSSC...
Thank you for the response Bug. Id like to keep the 160gb drive but i believe this is the culprit that is demanding so much power. There may not be a way to keep the computer on while the vehicle is off so i guess i will just have to live with it. I will also look in to that Carnetix you suggested and see how it looks. Thanks again.
Lappie HDD might help u out a lot
Still Planning and Scavenging Parts ------Software-----and anything else i can lay my hands on!!! :)
Acquired a Toshiba Satelite 4000CDT
HDD`s ****ed new one on way! 30gb Toshiba.
Yowza! I forgot that I switched to a laptop hard drive prior to switching power supplies. It was for the same reason you are having trouble. I thought that if I used a lower voltage HD it would solve my problems. It didn't and I got the Carnetix. On the other hand, I can't say it didn't help since I switched to the laptop before changing power supplies.Originally Posted by blackbravo
back when I had my ITPS (1+ year ago) I had the SAME problems....I couldn't understand it, but then again, back then I didn't know hardly anything about computers, etc (like I know that much more now...lol)Originally Posted by Bugbyte
on the laptop hd, I don't think it's that big of a deal?
I'm running a full size 200gig on the M1 (90watts) without any problems....but then again, I don't have a bunch of other stuff on the MOBO either....
good luck with it argetim!
