    Thank you, sounds good.
    I havent bought the PSU yet, so no need for that yet. Still waiting for my car to return from the workshop.

    For me personally the upper limit would be something like 192 hours and the lower limit 1 hour. Is that possible?
    Is there a case available for the DSATX?

    So has anyone found a pre-fabricated enclosure for the DSATX?
    There is no way I can fit it into my PC case, so I have to make it external.

    Or did anyone make a case by themselves and maybe still have the plans for it?

    Thanks in advance, guys.

    Hi Jeff,
    Is the DSATX 220-Watt DC-DC ATX PSU supplied with a 24 pins ATX connector, as now all MB's have 24 pins connector and ATX CPU 12V power cable has 8 pins?
    Thanks

    One more question - is your DSATX 220-Watt DC-DC ATX PSU working with S27-USB-SERIAL Acroname USB Serial Adapter as S19-USB-SERIAL indicated in the user manual is no more available? Thanks

    Its only 20 pin and 4 pin. But thats not really a problem. It would only play a role if you were going to use a CPU that draws a lot of power or overclock a lot. The extra 8 pins are only there to handle the added current (heat) for high power draw systems. So if the DSATX' output amperage is enough for your system, there should not be an issue. I have never had issues with with several mainboard and CPU combinations that had 24 and 8 pin sockets, with only 20 pin and 4 pin connectors in em.
    In theory, if you put out too much current over the 20 and 4 pin connectors, they can overheat and catch on fire in the worst scenario. Since that actually happened quite a lot since there are many people who overclock with stuff like dry ice and up the clock to 8+ GHz and high end AMD CPUs draw a lot of power even without overclocking, 8 more pins were added, to be on the safe side.
    So unless youre planning for such a system, you can rest your mind on this matter. And even if that isnt enough of an explanation for you, you can simply put your PC to maximum load and measure the temperature of the connectors/cables.

    Thanks very much for the info.
    Do you know if the -5V does matter or no , DSATX doesn't have -5V , as my MB pin diagram shows a -5V line, see pics bellow

    -5V is obsolete since ATX 2.0. No worries.

    This is a new Z87 Gigabyte MB, why they are still indicating -5V , I checked with an Asus Z87 too, and is also showing this -5V line , it's strange as this is not necessary anymore!!

    Do you have any experience with this PSU, any noise (rfi) induced in the audio system?
    Is this the best between the OPUS, M4-ATX and the others on the market?
    I'm about to buying one and want to be sure I get the best.

    Thanks very much for your answers

    Read up on it on Google about ATX specifications. -5V isnt needed anymore and many manufacturers dont connect it anymore to anything and some even leave out the cable completely.

    I had several M3-ATX before, which caused a lot of audible interference in my optical-out only audio system and even caused my monitor to flicker. With the DSATX that is gone. Also other people who use the DSATX all said to me that it is a very clean PSU in terms of RFI.
