  • n00b question about psu's

    Hey guys,

    I have the following:
    VIA M10000 board
    256 megs of ram
    160 gb 7200rpm hd
    slimline dvd drive

    It already has a dc-dc psu on it, that I plug an AC adaptor into for my house.

    I am about ready to put this into my car. Do I need to buy that m1-atx?

    I am so confused. I did searches but still cannot come up with an answer...

    Any help will be greatly appreciated

        What do you mean what is the voltage into my boards dc-dc?

        1. I gave you all of the facts that I know of. If there is anything specific that you need to know and where I can find it on my machine I will provide it.

        2. I don't know anyone else who has any kind of setup. That is why I came here to ask this question.

        Any help you guys can give me would be greatly appreciated.

          The adapter that you plug into the AC socket should have some numbers on it. A zoomed pic of it would be best, but at the least give us the output voltage and hopefully amperage. It should look something like "18V, 5.3A" or something along those lines. Also the make and model of the computer would help.

            1. as stratag said: look for something like 18-19V. If you are stuck get a decent pic of the back of your ac-dc psu.

            2. You are still not giving us the info. How do you expect people to help if you dont mention everything? What PC case do you have? Where did you buy it from/ do you have a link? There are probably a few hundred people with your setup. As you will soon learn on here most things you will think of have either been thought off and ruled out or have een done.

            This is probably simple case of needing a carnetix PSU but it may actually be easier to fit an M1 or Opus 120 depending on if you need more power.

              My case is a morex case.

              I hope the link and this information helps.

                Right, well now you need to look for people with Mroex cases. A good place to start is clicking the autolink that has just been added to the word morex.

                  Oh and 12V at 5A is 60W so you shoudl be looking at the 12XX series of carnetix PSUs.

                    Should I get this psu?

                    OPUS 80 watt DC-DC power Supply (12V Output) DCA5.080.12

                    Its an 80w. This is just like the M1-ATX right?

                    Or should I be looking at something more like this

                    CarNetix CNX-P1260 12V DC-DC regulator?

                    My case is the MOREX 2699R case. Which says comes with the 60w psu already.

                    I thank you for your assistance and patience with me because I am a n00b at this.

                      I was wondering....is my power supply external since I have the ac-dc convertor?

                      I am soooo confused.

                        you are still not reading are you?

                        The opus is an 80W and comes in 12V or ATX versions. The M1-ATX is 90W and outputs ATX voltages.

                        Did you even read the mp3car store sales info about the carnetix?

                        look:
                        The P1260 is designed to be a pre-regulator for CarPC cases that already contain an internal DC-DC ATX PSU, such as the Travla C-134 or the Morex 26xx/36xx cases, or for motherboards with on-board DC-DC PSUs (VIA TC10000).
                        also:

                        The CNX-P1290 is a 90 watt intelligent DC-DC power regulator designed to provide safe, reliable power to today's newest CarPCs......including Travla & Morex cases, as well as many of the Sumicom and Xenarc PC systems.
                        the 1290 outputs 75W at 12V and then has a secondary output.

                        the 1260 outpus 60W only which is the same as your morex internal PSU needs. Therefore the 1260 would do it but I would go for the 1290. then you can use the 12V to also power your screen (takes 8-10W so you have a margin of 5-7W minimum) and you can also power things like USB hubs off the secondary output if you have lots of devices to reduce the load on the PC usb and this the morex which is limited at 60W.

                        Alternatively, you can take out the morex PSU and use an M1-ATX but i would go with the carnetix.

                        you really should read through all the info and make sure you knwo what you are doing and deduce the solution for yourself.

                          The USB devices I will have will be my wireless keyboard and mouse and my delorme earthmate gps.

                          If I got the 1290 would I replace the exisitng psu in my case and just plug it there.

                          I really appreciate your help. I am sorry I am not done with this. I just want to get the right psu.

                          Thanks

                            No. You will install the 1290 in your car and connect the PSU in your case to it.

                            Don't take the responses personally. You're asking some basic questions and you're a little confused about what you need. Hopefully, you have read the thread in the FAQ Emporium about "Everything you need to know about power supplies" already. If not, click the link in my signature and you'll be taken to a FAQ to the FAQ's and will find a link to that thread.

                            Here's what's going on with your system:

                            1. You already have a power supply in the case of your computer. Good.
                            2. You can plug that supply into your house IF you use the AC-DC converter that you already have.
                            3. You NEED to be able to do something similar in your car.

                            To accomplish that, you'll want to do something similar to what you are already doing in your house with that AC-DC converter. That is what the Carnetix is for. It will regulate the power, taking care of overvoltage and undervoltage situations in the car, supplying clean 12 volt power to the PSU in your case.

                            As an added bonus, it will signal your PC to start up and shut down when your car does.

                            Finishing your installation:

                            Buy the Carnetix 1290, install it in your car and hook your PC up to it.

                              cough cough. - ie you leave the morex in when using the carnetix. The carnetix is a regulator with a little bit of extra stuff to startup your PC. The morex and M1 are ATX PSUs. The M1 is like having thr morex AND carnetix.

                              I think you should do some research on the carnetix to look for issues that other people have had with regards to installing.

                              You can also download the manual which you should always do before you buy anything. Have a good read through and get familiar with how it all works.

                              good luck.
