Thread: Help! Having issues wiring CarPC Pro v.2.5 shutdown controller & Opus 150W

YOu have a shutdown controller that you don't need.
You don't need an inverter.
The Opus 150w will probably power your motherboard and has a built-in shutdown controller.

Now if you have a laptop, you've got all the wrong stuff.


For anyone reading this thread in the future:
Philly#1 Lex here is a prime example of why myself and a lot of the other long-timers at these forums tell new members to go to the FAQ Emporium and read the posts there and search the forums for various topics and read the threads that result.

Had you done that, you'd know whether you have the right components for your setup, and likely how to wire them up.

Just to clarify what DarquePervert is saying:
Opus 150 already has a builtin shutdown controller and a DC-DC power supply which means you do not need to use the extra shutdown controller you have and there is no need for an invertor either as the opus will provide the power. You just have to make sure your system's power needs can be met with what Opus can put out on its rails. That information you can find in the FAQ section DarquePervert is suggesting you should read.

And we're telling you that that the Opus power supply has a shutdown controller built in.
That shutdown controller is meant for a PC motherboard, not an amplifier. It's not going to accomplish what you want anyway.

I dunno thats a 150 opus... same as mine.... so it wont turn off the USB ports properly so that shutdown controller will come in handy if he wires it before the opus

IMHO Shutdown controller doesn't solve 5VSB issue with ATX compliant power supplies ( like Opus 150W) ... It only switch on/of mobo .

I know now that the shutdown controller was not needed for controlling power, But I want to know if I could wire it before the Opus to control the amps and monitor temps without have to buy other pieces? ChewEboy can you explain what you mean buy wiring before the Opus. Or anyone for that matter. If it can be done please share if not just tell me no it cant be wired before the opus. thanks

I think that shutdown controller is too expensive solution if you use it only for starting amplifier. To start amplifier run wire from your carpc ( may be from 12V drive supply connector) and optionally through some low-cost delayer.

well all the ones that are sold on mp3car all have a volt meter that cuts off when battery power reaches a certaint point....


so it would cut all power to car pc if set in line before it




basicly your soon to find out that the opus 150 is flawed and does not cut power to the USB ports when it shuts the PC down....

so if you have lots of USB things conected like GPS, bluetooth or what ever ya have... the car battery will be drained quick.... leaving you with a flat battery...


(I must of had about 20 flat batterys before finaly working that out)



so you either need to use a shutdown controler or mod the OPUS

the company OPUS will mod the power supply for you if you send it back to them


or you could mod it your self...... see here..... http://www.fmev.com/opusmod1.htm
