    Default Interesting design on NMB power supply



    This was uploaded by POM MJ on badcaps, thinking about buying one now that he posted this, interesting design on it.

    Is the primary transformer those two small ones in the corner? And what is all that on the secondary pcb before the secondary heatsink?

    Those two small ones are PFC boost inductors using EE cores.
    The main Xformer is the large coil on the "secondary" PCB.
    Have seen it for a while but still can't understand its oddball design. Really odd.
    Two +12V rails are independently regulated, as far as I can tell.
    It's been a hard day's night and I've been working like a dog.

    here I posted some Pics of a not so odd NMB Design.

    That one could be the one from a FSC Celsius 670.
    Used to have such thing but I was unable to get really good Pics if it - before I sold it...

    €dit:
    OK; here are my pics of the NMB from the Celsius 670 Workstation.

    I was wondering why there was only 1 cap per rail, but then I saw they were 5600uf!

    Yeah, that's a really interesting design.
    Some Pictures got lost somehow, imageshack must have deleted them...
    to bad I couldn't get my hands on the Etasis 750/850 Dual PCB Design used in the ST-75ZF...

    Sorry for the crappy Pics of the Celsius (I think it's also called Kelvin) Workstation...

    Well if you're not good in taking things apart and putting them back together you shouldn't take it apart.

    It's a real pain in the ass to take this things apart and put them back together, especially if you don't know what's waiting for you.

    But aside from that the inside is really interesting and a bit different from other things you've seen

    Ran into this with my dps-700. I put it back together, and no dice. The cable with a bunch of smaller wires on it wasn't seated all the way down, so it wouldn't start.
