    OPUS 150watter just bought :/ few questions

    I;ve just placed my order for the OPUS 150watter, after having enough with my invertor and its extreme behaviour. Thats another 170 spent, i just hope its not a waste this time

    anyway i was wondering, is it possible that i could keep my shuttle pc on all the time, and everytime i drive somewhere in my car or will i have to use it 'now and again'? (note i dont have any amps subs etc, just a plain stock car - 45AH battery) - {if the answer to this is no, will an optima yellow top allow me to keep it on all the time?

    What size fuse shall i use for the PSU?

    Thanks for your time.

    I also want to know what size of fuse is best.

    i read that there is already a 15A in de opus itselft but i want one on the battery to so

    150w / 12v = 12.5A -> 15A fuse ?

    or should the fuse on the battery be bigger than 15A ?, i searched the forum for this and found that some use 30A fuse ?

    and another little question:
    is it possible to convert the lilliput's cigratte lighter to molex so i can get the 12v out of the opus to power the lilliput ?
    I think it will be because it's only 9W.
    But haven't seen a pic of somebody who did it.

    Well, i believe a 30a fuse should be fine, but then again i dont want to take a chance.

    @Bitflip, I don't understand your first question entirely. Yes, you can leave your PC on all the time while the engine is running. Once you stop the Engine, the Opus will handle shutting down your PC and the PSU so that your battery isn't drained. If you want, you can also add your own switch(es) to add manual overrides to this behavior. I have no idea if the Opus has enough power to supply your Shuttle. Search around.

    If you want a fuse to protect the wire running from the battery to the Opus then the correct current rating for the fuse depends on the current carrying capacity of the wire you use. Use the search button. There are several threads with links to wire and fuse sizing guides.

    If by 'convert' you mean, hack it off and connect the wires to the molex connector, then yes! Why not? Of course, it depends on how much stuff you want to run on the Opus...if you're not overloading it, there shouldn't be a problem.

    so i just depends on the cable ?
    if i use a cable that can handle up to 35A
    a 30A fuse would be just fine then before the cable melts

    Laidback i have same system as you with a 7200 rpm 3,5" hd.
    so you think it would be possible ?

    Yep, that's the theory. Again though, do a search. There are some really good guides about how to do proper power distribution written by some people with lots of experience.

    I run an m10000, Lilliput touch screen, 7200 rpm 3.5 hdd, USB GPS, Orinoco pcmcia card and a crappy USB sound transmitter thingy from my 100W PSU.

    Put it into Stabdby. It will resume about 7 seconds after you switch on the ignition. 5 seconds for the Opus to sense power, and a couple of seconds after that.

    If you don't want it on every time you start the car, then wire it up to a SPST switch, rather than the ignition wire.

    Thanks for all the feedback guys

    Rando - what i was trying to ask was; people with opus psu already, is there a limit to how long you can use the pc for, i.e before the battery runs down, and the low voltage level kicks in?
