    Overloading an opus

    Overloading an opus

    What would happen if you overloaded an opus would it just not boot up or would it harm something.

    I am talking if you like hooked up to many things is it going to burn out the opus or could it harm some of your computer parts. Or does the opus have something built in so it just wont work if you have to much hooked up to it

    If you overload an opus as far as can tell it wont have enough power to power some critical componants like hard drive and motherboard and lcd

    But its not like you are going to hook up one to many things and just fry something, right?

    You should be able to tell if you are hooking up to much, right?

    From my experience if you overload the opus, then it simply won't power up the PC. I have a problem now where the OPUS is right at it's threshold with one Motherboard hooked up, so when I enable the wireless card, the computer blue screens and shuts down. If I try to start the PC with the wireless card on it gets to where windows initializes the Wireless card and reboots because of too much power. With another Motherboard and everything else the same I can run the wireless card, but as soon as it finds an access point the music gets jittery and the PC eventually freezes, then reboots after a few seconds.

    I may have another issue going on here too, but I know the OPUS is right at it's capacity with my system.

    It's more of a long-term (meaning several months) issue. The Opus, to my knowledge, does implement some over-current protection so an immediate up-in-smoke scenario shouldn't happen unless there is a short. It also simply won't power up the PC, or the PC will be unstable if you are too far over it's rated output.

    Over time, however, components will degrade at an increased rate due to electrical and heat related stresses present at close-to or over the rated wattage, even though it may run all your hardware.

    Yes, I'm currently running the screen (only draws 7w) from the OPUS and I have an MSI Lite MB, with PCI Wireless 802.11, PCI SB Live!, and AGP 128MB video card. It's weird how I can have everything on and working while sitting in the driveway including browsing the internet, but when I'm driving around it skips and eventually crashes. I think the wireless card is searching for new AP's and dropping others and it's causing the system to draw too much power somehow.

    Anyways, if I were just getting into it I'd go for one of those EPIA boards or whatever the other people are using with the built in processor.

    When I first got the OPUS I had to call them a few times to get everything set up and he was very helpful. We narrowed it down to my processor being too big (i.e. drawing too much power) for the OPUS, so I downgraded from a 1.1 GHz to a 1.0 GHz and it worked. However, I still highly recommend one of those other boards with carPC's...the reg. mini-ATX work, but they draw more power than what's really needed.

    that video card probibly is not helping either, high powered video cards draw alot of juice, if you dont need it, go with somehting smaller
