    What is a sproggy psu?

    I searched ........pages of threads about sproggies but nothing that flat out says it. If someone could just even put a link to help me out, that would be good.

    I recently won this............DC-DC PSU - SPROGGY - LOOK , so now i need to know what i need to complete this sproggy and what they consist of etc. THANKS

        Copied from the page linked:

        Parts NOT INCLUDED

        MAX 787 (MAXIM)
        MAX 788 (MAXIM)
        T6 TRANSFORMER (COILCRAFT, RENCO, WILCO)
        LM2587-12 (NATIONAL)
        47UF / 5AMPS INDUCTOR (COILCRAFT, RENCO, WILCO)
        10UF / 5AMPS INDUCTOR (COILCRAFT, RENCO, WILCO)

        Don't know what you mean by "what will the sproggy do to my pw-60". How about "replace it - they do roughly the same job".

          I got that, ok well i bought this psu before doing research on sproggies and what not, cause i seen it on eBay and NEEDED a DC-DC psu. So now I have the DC-DC psu and the shutdown controller, thats all I needed..........i think. What is the sproggy for? is it just another dc-dc psu or an add on for that other dc-dc psu? Will this setup also prevent from starting up during cranking or is that Just the opus that does that?

          thanks Rob!

            Yep, the sproggy is just another dc-dc power supply. It uses a switched regulator for the 12v so in theory it should avoid a reboot during cranking (claims it can operate down to 8v).

            As dc-dc supplies go it is not that high powered, especially on the 12v line if you are running a number of drives.

            Afaik, there is no shutdown controller built into the sproggy - the chip at the end is for the power good signal.

                  I highly recommend trying to use the sproggy instead of the PW60. The problem with the PW60 is that it only supplies 1A for the 12V supply and most hard drives & CD ROM's require ~1.5amps peak. Don't be surprised if your computer starts hiccuping when powering both a CD ROM and hard drie with the PW60. I just ordered a sproggy 2.8 and I'll let you know how it works out.

                  The sproggy supplies much more power at all voltages. To order the missing parts for the sproggy go to the sites listed below and request samples
