    PSU mumbo jumbo

    Hi all,

    I have been beating my head against a wall trying to get all this sorted in my head and there are too many names, specs and alternatives so I thought I would throw all the questions down and hopefully some other newbies will prevent an innocent wall from punishment.

    Here goes:

    Morex - power supply and regulator package?

    Carnetix - primarily a regultor but can also be used to power LCD?

    ITPS - regulator with startup and shutdown controller

    PW range - power supplies only?

    OPUS 90 & 150W they do everything in 1 box

    Key Power
    Zantech
    Bicker

    Above 3 are full size ATX PSU's, like the one in your desktop machine only then run off 12v?


    With the smaller "snap in" PSU's do they all come with a regulator, is a regulator absolutely necessary, can you swap and change the regulator?

    ie ITPS with PW / ITPS with Morex or Carnetix with PW / Carnetix with Morex


    Could the more powerful (200w) snap in PSU's power a full size ATX with the use of an ATX extension lead, figured it would need the extension lead as physical obstruction may prevent it from snapping in on a full size ATX board.


    If you can use the 200w snap in board for full size ATX, could this also be used to power full size drives, ie 1x3.5"HDD and 1x5.25" DVD


    I have read that not all full size, high power PSU's are regulted correctly (http://www.carnetix.com/additional_i...PeoplePlay.htm) does anyone know if Key Power/Zantech/Bicker fall foul of this?

    What the hell is a sproggy?

    Thanks in advance for any replies, you might have just saved another wall from uneccesary pain

    Best regards

    Darren

    If you want all in one solution, get the Opus or the Sproggy from Mastero and put it together yourself or Mastero can do it for you.

    Morex 60W - PSU only. Prefereably requires regulation. Typically found in "Mini ITX Cases" from companies such as Morex and Travla

    PW* - PSU Only. Preferably requires regulation.

    KeyPower etc - Unless they state otherwise, just a PSU and they require regulation.

    ITPS - Regulator and startup/shutdown controller. Requires at least 13.3V in to give 12V out. Therefore won't survive crank (in most cars) or work with the engine off.

    Carnetix - Regulator and startup/shutdown controller. Takes input voltages from ~5-18V.

    Opus - Regulated PSU with startup/shutdown controller. Survives cranks, input range ~7-18V

    Sproggy - High power, regulated, startup/shutdown controller. May be cheaper than other option. Disadvantages: Have to build yourself, may be difficult to get/find all parts.

    Best solutions (in my opinion):

    Carnetix + PW*/Morex 60W - Already have or are getting Mini-ITX case with 60W PSU inside, tight space requirements (Only 4 wires are run to case, the main unit (which is small anyway) can be placed elsewhere out of the way)

    Opus 90/150W - Don't have any existing hardware, are not getting Mini-ITX case, no size constraints, require more than 60W power (150W Opus will power a P4 system easily)

    I have never used a Sproggy, so I can't comment on those in relation to the other options that are available (i suck at soldering, so making a Sproggy isn't a good option!)

    Confused, thanks for the swift and informative reply

    Do you have any information about the hi power (200W) snap in boards powering a full p4 system, could this PSU be used with the carnetix regulator?

    I think if this works it would be a cheaper approach to an opus, price is an issue at the moment.

    Cheers

    Carnetix is only 60Watts. No good for a 200W power supply.
    Old Systems retired due to new car
    New system at design/prototype stage on BeagleBoard.

    the carnetix will only provide 60w anyway, and most of the power on those snap in type PSUs is just unregulated 12v

    i assume you mean something along the lines of this which would work rather well ... i personally would only run it in conjunction with a ITPS because of the voltage regulation it provides anyway the controller would be nice to have too. that still puts you at roughly half the price of the opus ... but don't expect it to survive a crank. also make sure this is rated for 200 watts continous. a while ago i read a thread that addressed these issues. the poster linked ot an outside document about what companies don't want you to know about power supplies ... or something like that ... now i didn't rtfa but i would use this and try to find the article or find someone who is actually that is using it for their opinion. in my opinion ... save up for an opus

    If you want to send unregulated power to all your components, then yeah!

    The ITPS still only provides 60W of regulated power. To use any more you've have to bypass the regulator.

    True.

    200W unregulated continuous power. No way that's going anywhere near any of my components.

    Link to said article

    If you need more than 60W of power, and don't have an existing DC-DC PSU, then yes. If you don't need more than 60W, and already have a small case with a 12v PSU inside it, get the Carnetix, as i said earlier

    Thanks all,

    seems that i can have up to 200W of power, just not regulated, just not gonna happen either, not on my machine anyway.

    I already have a machine but its a full ATX which isn't in a case, I kinda integrated the whole PC into the dashboard with the glove box now being the motherboards new home, hence the reason I was asking about big wattage power supplies, I am also running full size drives.

    Like I said cost is an issue at the moment but I need to get rid of the inverter, it just isn't up to the job.

    Im hoping to go the Billing aquadrome meeting, anyone else coming

    Darren
