  • OPUS to 22" LCD screen

    I have a Sharp 22" 16:9 LCD TV. It runs on 13v and 65watt. If I take 12V from OPUS and connect to the TV, will it work ? Will it break or burn anything ?

    I think thats not the best Idea, becaust 1st thing is that i don't think Opus provides 5,4 Amps on the 12V line.(Don't know the specs) And the other thing is that even if it would provide so much there would be not much left for other components like 3,5" Hard drives ore so on! Your Opus would be overloaded very fast!

    I would rather buy one of those DC-DC Laptop-Power supplies (from Ebay etc) which output constantly 12V and use this for the screen.

      well the main question is, the transformer for the LCD gives out 13V to the LCD screen. If instead of using the transformer and feeding 12v power directly to the LCD, would it burn anything or should it work properly ?

        Whew... Might work... But man... That just seems like it would be risky.

        Any reason you don't just run to walmart and spend 15 bucks on an inverter? Seems like a much safer way to go to me.

        Plus, like he said, if you CAN power that thing off of the OPUS, you're not going to have much left over for the PC... Unless you have like an EPIA system with a single notebook hard drive or something...

        Still, I'd go the inverter route.

          DO NOT FEED the 12V from your car directly to anything that was not design to be connected to a car electrical system.
          The power from a car is unregulated, meaning it can range from 7v to 16v. This will burn your LCD.
          You will always have to put something ( opus, notebook DC-DC, Inverter ) between the car 12v and the LCD to regulate the 12V.

              I am running on an Inverter right now, but it make noise on the screen. I also know the power in my car is unregulated, that's why I thought of using an OPUS or other regulated power supply. I was just wondering if it would damage the LCD if i give it 12V instead of 13v.

              I am however planning to run TWO opus in my system.
              One for the CPU, motherboard, RAM, video card, and sound card, the other one for floppy drive, harddrive, DVD, USB hub and devices, a Xenarc 10" LCD, and MAYBE the 22" screen.

                Ahhh, I see.. Have you tried any noise filters/conditioners or anything like that?

                With dual OPUS's, I'm sure that would help with power problems. Though I'd change the balance a bit. I'd imagine a 150watt OPUS would handel all of your computer stuff without a problem. Then you could have your 22" screen, the Xenarc and the USB off another one.

                I have all of this running on one OPUS with not a single problem so far:

                2.4 ghZ Celeron processor
                One stick of mem
                One 3.5 inch hard drive
                One CD drive
                One DVD drive
                My 7" lilliput touchscreen
                4 port USB hub

                So I'd imagine your whole computer would do fine on one of them, which can iliminate problems that can come up with running 1/2 your computer on one PSU, and ther other half on a different one (I blew up (almost literally, there was smoke) one of my old power supplys doing just this).

                Anyway... With the LCD rated at 13 volts, I can't imagine you'd do any harm by putting 12 volts through it. I can't really see how that could damage it, at worst, it just might not work right... Don't quote me on this, though, as I'm no electronics expert. I'm just saying, not putting enough volts through it is probably better than putting too many through it.

                Good luck, hopefully it will work out for you

                  Speaking of which, would I have any problem powering my computer with two opus ?
                  I probably can power my computer with just one, but if it case there's not enough power, say I need more power to run a DVD drive, could I just get another OPUS and connect the power plug to the DVD drive ?

                    I used to run my DVD drive off an AC power supply and inverter, and my EPIa board off a morex DC-DC power supply, never ran into any problems, except when the inverter kicked the dust and overheated itself ><. If your going to use an inverter, make sure you get one with the right specs! A 100watt inverter will not run 300watts of power, just ask the slight burn hole it made in my tunk carpet a few years ago before I knew baout this stuff .

                      I am going with two OPUS. I still have the inverter for my PS2, VCR, and the 22" LCD.
                      The inverter I have is rated at 700watt with 1400watt peak. Hopfully it won't burn itself out.

                        The 150W has 5A on the 12V...
                        The new 80W power supply will have 7-8A on 12V, but it'll only have 12V or 12V&5V that might be the way to go since it's going to cost about 80-100$
                        But you'll have to wait around 2-4 weeks for it...
                        I'll spout simplistic opinions for hours on end.

                          Why don't you save the money of the 2nd opus and get one of these Notebook car adapters and use this to power your screen. I bought one of these for 30 an it has 120W's
                          An you won't hav any troubles with 2Opus, Power-Good Signal or anything else!

                            I agree, search ebay for a 12-14volt laptop adapter, its regulated , cheap (10-30$), and you can cut the plug and wire straight in... although these low voltage adapters are usually 2-2.5amp rating(check the back of the monitor to see what the AMP rating is...

                            Im using a 13" lcd monitor(just mounted last weekend) and its 12v, i used the car output only at first and it worked fine, but still i got the 12v to 12v adapter from radioshack (1.2 amp max load), and the monitor was 1.25 amp, and it works great with no worries.
