    Please add a note to the pico psu series

    please, when there are not any notes that it is not capable for use in the car, people buy it and blow things up, making them angry that no one told them that it didn't work in the car...

    Yes. It took me a little while to figure this out myself. Many people don't read the specs. They just read the title as say "160 watt pico psu" and buy it and then don't feed it with regulated power.

    Many fail to understand the specs anyhow - so many think a car is "12V" as opposed to the (IMO) standard design spec of 8V-16V, else at least the VERY common 15V upper (typically 14.7V) and down to whatever dip is normally experienced - eg, ~11V with lights/brakes first applied, or 9V-10V during cranking and maybe the start-up of hi-powered engine cooling fans.

    But omission of such info means more sales for such "12V Regulated" products (at the risk of future brand avoidance etc).

    A related aside - IMO, PSUs that handle down to an even lower ~6V should be applauded and appreciated. (Even my designs try to meet or exceed a mere minimum of 8V, though I well & truly appreciate my ignition system and startermotor that start a cold (10C) engine - not that that is car PC & PSU related.)


    But I too argue for appropriate warnings. If not for any implied obligations or onus, then at least for goodwill, AND to save us wasting money.

    [Yet again thanks to soundman [maybe we are a bit out of the norm!]. And thanks to kolton for his supporting experience.]

    i am thinking this needs to be retitled as "the mp3car store stinks" to get their attention... i have made a couple recommendations like this in the past, and all appear to have been missed by the powers that be... while it is a nice warning for fellow experienced members, it does nothing in the way of store reputability, or return customers...

    I support you.

    As I do with any support I can offer any claim (fair or misleading advertising etc. hint hint...).

    Ditto. It's not regulating the power. You need an intelligent psu or other regulated psu

    Is there anything wrong with using a PicoPSU with a CNX-P2140? Other than the expense, it looks like a very flexible solution.

    I've used PicoPSUs for many years in miniATX servers, using 12V wall warts. Very reliable, never had a failure. To claim that you shouldn't use them is not fully accurate. Just make sure you feed them filtered 12V power and you are golden.

    Yes, same question. I thought that regulated power supplies were relatively common in car setups. Shouldn't the recommendation be that they must be used with a regulated power supply rather than not being suitable for use in a vehicle?

    ^yes, i agree with both of you-- my take might be a little overzealous (though still ignored by mp3car mods). though, even if you have a pico psu left over from another project, i really don't see a reason to use it in-car, because you still need a power supply that provides regulated power--many times any other psu will connect directly to the motherboard without modification, where attempting to use a regulated psu with a pco psu might require modification to the wiring harness.

    your right.

    there is nothing wrong with the pico psu models, but the way they are marketed on this specific forum. while i agree that the pico psu series does great in the home pc/server area, this forums primary focus is in-car computing, and in a car, using a pico-psu by itself is a bad option-- you would require 2 power supplies to do what 1 will do(and how many people are going to buy 2 psu's for 1 pc?). also, before making this thread, i have read of many new members that choose it as a option for their carpc build because of the low cost--not realizing that it is not suitable for car use by itself. and, by the fact that many people don't post until there is a problem, i suspect that only half of the people considering, or purchasing the pico psu bothered to read any warning of why not to use it by itself in car.
