How to power the PC OUTSIDE the car?

**msink** · 03-22-2004, 10:44 PM

Hello,

Wondering what the best way to power a DC-DC powered car pc is when its not in the car? Do you unhook everything, and then use a AC-DC PS inside the home? Or is their a better way to handle this, maybe with AC-DC converter?

Thanks,

Mark

Like you have the power blocks for laptops. Same idea.

Thank you,
Which type of plug does the Opus 150 and 90W PS take, and is there a favorite converter people are using inside the home?

Thanks,

Mark

Currently I have inverter setup in the car, but soon to be replace with sproggy DC-DC PSU. My Mastero/Sproggy 3.0 can't handle the hardrive. Once I have DC-DC PSU, I just use AC-DC PSU inside the house. It's not that complicated and only 2 connections to plug and unplug.

well you only really need to unplug the atx connector and hard drive.. and parhaps a cd/dvd/cdr whatever drive if you have it. so a normal atx supply should be quite the best route to go

If you are using an Opus, you chould just disconnect the ATX P1 connector from the Opus then put a gender changer on you AC-DC power supply, then hook up your AC-DC with gender changer to the ATX P1. That way you only need to unhook the one power plug.

What about an AC-to-DC converter like this: http://www.tripplite.com/products/in...ed_dcpower.cfm

Would these get the job done to run an Opus supply? How many amps does the Opus need to run?

Uh, well... power = voltage x current... so 90watts / 12 volts = 7.5 amps. It's not so hard to just swap out the power supply though.

For 150W Opus:

AC to DC Supply
120V Input
12~15 Output
10~12.5 Amps

Right?

While my box is not in the car, I use the AC-DC power adapter that came with the case (morex cubid 2677R) which provides +12V DC:

I replaced the existing female power plug and wiring with a new plug wired to the Opus. I then added another female power plug for the remote turn-on signal. I added an SPST switch with a diode to override the remote turn-on signal. When I bring the box inside, I simply connect it to the AC-DC power adapter and flip the switch.

Code:
