    SDC should be Pluggable - not a mandatory purchase. Everyone has a different use for these things - and most of us already have one. (just a thought - take this with a grain of salt - it looks like this thing will be expensive - cut costs here)

    Fan - don't necessarily include it. Those who need it can add it. Most people are willing to spend $10+ on a high-quality silent fan and throw out the cheapie. As long as your circuit won't self destruct when overheated - skip the fan.


    Oh yea - get this thing on the market! Skip development of the fancy features *cough* sdc, relays, serial port, etc *cough* and start shipping now!

    Keep in mind - there is a vast market for a DC-DC which puts out 300W. Period. That's It! If it has additional options, cool, but the added development time will hurt your bottom line. (Opus is on the way)

    I'd agree with PatO if you were targetting purely advanced users.... unfortunately though I will suggest you keep in all these features as I think (correct me if I'm wrong) they add value but shouldnt add much bulk to the cost...

    also, integrating SDC, fan control, etc into your small case is a positive for all... integration is key... I dont want a PSU, an SDC, a relay controller, a fan, etc if I could have some of these grouped into one small unit...

    I thikn you are coming along quickly, so keep up the good work and integrate as many useful features as you can!

    I heard from OPUS, that their new PSU is coming in 2 months. So get something out quick!

    i heard the opus will be 200w or 250w.... I still prefer buying from a member, support on here is always good (i personally didnt have a great experience with opus support despite others' experiences)... also your SDC should be much better, and addon boards would also make your product even nicer... plus it is probably smaller than the opus..

    opus is really good, but a large part for it being so highly considered is that it is the sole-player in this market....

    The on-board SDC is going to be a higher priority than the expansion board, so the release of the PSU is not waiting on the development of the expansion board.

    The aim is to make this supply capable of functioning as a standard ATX PSU (although perhaps with an enable-disable input available for external SDC's) when operated without the internal SDC, therefore as long as we get the details of that interface sorted out it's possible that the PSU could be released as soon as dragon's got it ready, and releasing the SDC when that's ready (after all, it's a little harder for me to build an SDC for it when i don't have the PSU to test it on)

    I will speak with dragon on the matter.
    But don't take it from me! here's a quote from a real, live newbie:

    if the hatdware for the PSU is already there, the PIC etc fitted, the firmware could be delivered at a later date right?

    I suppose that's possible, as the PIC in question does support a bootloader for programming via serial. however, the bootloader that I typically use is not licensed for commercial use, so I'd have to find a different one (writing my own would take enough time to defeat the purpose of releasing without firmware)

    However, the idea is that the SDC will be a separate board that plugs into a socket, thus it will be removable. the hope is that putting a certain jumper into the socket in place of the SDC should allow it to operate as standard ATX with an external turn-on line (ACC, or from an external SDC). That way it would be easier to release the PSU without the SDC at all, rather than with SDC but not firmware.

    Don't quote me on any of that though, I haven't finalized it with dragon.

    you sir, are making my mouth watery with all these predictions!

    I can't wait for this, although I'd have to think what to do with my 2 opuses once they go oboslete!
