  • I'm so confused about power options

    Too many options, please help. I read the faqs and through that last five pages of threads and I'm still lost. I gather an ideal system consists of a Regulator, startup shutdown controller, and power supply correct? Since there are so many options out there can someone post which works with which or lead me to an already existing thread?

    I am going to be using a epia m10000 board

    So far I bought a pw200m that I am now thinking was a mistake. To complete this power option I was going to go with a carnetix 1260 that is both a regulator and startup/shutdown controller. Now I'm confused because the pw200 supposedly will supply too much power to the cd drive and hardrive.

    Now I am thinking that I should have went with the opus 90 watt power supply which has a startup/shutdown controller. Since the carnetix has a startup shutdown controller too, what regulator do you go with that doesn't have one?

    I've also seen standalone startup/shutdown contollers. Which power supply's and regulators do those work with.

    Thanks,

    Dan

    Actually it sounds like you have a better grasp on the options than many newbies

    Wherever you heard that the pw200 will supply "too much power" is total bunk. A power supply makes power available - if the device doesn't use it, that's fine.

    The opus has a built in regulator - you do not need a seperate regulator.

    The direction you were originally going would work. The opus would also be a fine choice, probably a bit easier as its a one-step solution (and therefore the advice usually given to newbies: "Get an Opus!" ).

        sorry to jump in on you post, but I'm trying to figure out if a 90 watt power supply will be enough to handle what I want, I asked in the newbie forum and they told me to use a power calculator or whatever but I have no idea how much each thing uses and no one seems to want to answer me there. Here are the specs I'm planning:

        VIA EPIA M10000 Mini-ITX Mainboard
        512MB DDR RAM
        Panasonic Slot Load DVD-ROM/CD-RW Combo Drive
        2.5" 80GB HD
        SB Audigy 2 ZS Sound Card
        Lilliput 8" VGA Touch Screen
        M1-ATX 90 Watt - Smart Automotive Power Supply
        OBD-II
        Win XP Pro
        4 port USB hub
        Some kind of navigation (any suggestions?)
        my setup - finally

                The problem with this is interfacing the sextent to the computer. That and it limited to night time hours.

                  This will work splendidly. I power mine with a dc-dc psu like yours and a Carnetix 1260. No problems. Just buy the Carnetix and you'll be done.

                        so would using the PW200m and the Carnetix 1260 be better than using the Opus 150, it seems a better deal to spend $145 for 200 watts vs. $180 for 150 watts (they both will be able to deal with cranking issues and have the startup/shutdown control, right?)

                          The Carnetix is a 60 watt regulator. Even though the PW200 says it's 200, it's not able to supply that continuously and even if it could, the Carnetix wouldn't supply it.

                          The wattage issue is a non-issue (for the most part) if you're using a low power system like the Epia. Mini-ATX boards and P4's need more power and you often need to switch to an inverter if you'll have to supply more than 150 watts.

                            ok, so can i get away with using a 90 watt power supply for my above mentioned setup (fourth post from the top), or do i need to spend the $180 to get the 150 watt supply?

                              Guys,

                              The PW200 is a is a 60 Watt regulator (see THIS article). It provides 60 watts of REGULATED power and provides an UNREGULATED +12V output. This unregulated output is basically a wire directly from your battery/alternator to your motherboard. This WIRE is rated at 12Amps (ie it won't melt @ 12A), and hence the +12V/12A rating.

                              The P1260/P1280 can be used as a pre-regulator for the PW200 so that the PW200's +12V output becomes well regulated and won't fry your mobo. However, the total output of this combination is limited by the P1260/1280 to around 60 watts.

                              A much better combination would be a Casetronic C4-CT-DC150L ($45) with a CarNetix P1900 in front of it. With this combination you can get about 120W (135W if you include the secondary output of the P1900 @5V/3A).

                              Sorry to be so blunt, but many people are confused by the PW200 specs.
