Well, today I sent away some files to China to get some pcb's made for an ATX Control Board.  This board will talk with the motherboard and manage the computer power supply accordingly.  It should be able to be plugged into the P24 socket of any ATX compliant motherboard and manage power on and shutdown procedures.  As an extra it has over-current , under-voltage and over-voltage protection for all the rails going into the P24 socket, but not for other rails for HSS/SSD, USB cards, cpu et cetera.  If warranted, these can be added at a later date but not to the ATX Control Board because it does not handle those voltages other than simply turning them on and off remotely via an AC mains relay.  This relay sits on its own little pcb and is controlled from the ATX Control Board.

So, hopefully I can get this to work first time round, and then the fun and games can begin as various power supplies are developed and trialled to sculpt the best sound.

ATX Control Boards and Relay Boards arrived this week.  All the parts are here to populate them, but I am waiting on some transformers and heatsinks for the power supplies that these boards will control.  Hopefully next week everything will be here but in the meantime I will populate these boards and do what testing I can this weekend.

The ATX Control Board is all SMD (a first for me) populated both sides.  You can see the P24 connector that will got directly to the P24 on the motherboard.  The little single sided ATX Relay Board will go down in the first stage of the power supply (a separate box) and will switch the AC for all rails that are not 5V Standby.

The first power supply that I will build up will consist of 8 rails using LT1083/1084/1085 and TPS7A4700 linear regulators, often cascaded to get a good noise result by letting the first stage do the heavy lifting of the voltage regulation and then a second stage inside the computer with minimal voltage drop (and therefore heat dissipation) and hopefully some excellent low noise performance.

Once I get this all working, then I will build the really high performance supply using some newer but more difficult to use linear regulators to see if I can get a better result because of even lower noise.

Hi Anthony,

You worry me a little. I wonderd what you are going to use these regulators for, they are all 1-1.5Ampere max. Everything except the processor? The motherboard can draw some power on the 3,3V for peripherals and mind you that 1,5 A is only 5Watt. For harddisks and PCI usb cards the regulators you mentioned will be ok. Be shure to add sufficient heatsinking even when cascading.

I would use beefier LDO regulators or bootstrapped ones for the motherboard and processor (100w = 8Amps @12V). At these amperes you should have considerable heatsinking even with LDO.

My i5 PC consumes over a 100W on boot. When playing music the LPSU heatsinks get really hot in summer and it supplies less that 70Watt from the powerstrip (for 50 Watts that the pc uses). That heat comes from the 20Watt difference in input and output.

Regards, Coen

Hi Coen,

The LT1083/4/5 are nominal 7.5A/5A/2A respectively, so there is plenty of current available.  Perhaps you have them confused with other LDO's?

The heat sinking is quite something, and if the first stage is run at their maximum current load the LDO's will dissipate about 90watts between them, so I have two great big heat sinks on their way to me that should handle that load with a 20C increase above ambient, which in my experience will still feel quite warm.  There will even be two heatsinked diode bridges for high current rails.  At this stage I have opted for off-the-shelf power transformers and I really don't know what their temperature rise will be, but hopefully not too high.

Anyway, hopefully I can get the ATX Control Board to work first time.

Regards,

Anthony

Hi there all and especially Anthony of course !

It looks like we're 2.5 years from the start of this subject and forum topic;
Right from the start I was involved but I never granted myself the time to really work on it, except for this one occasion where someone else was going to make an example for me, which up to date never got working (but I never hunted down the bloke who so-called could do it).

The last thing you heard from me regarding this was that I bought a Teradak on behalf of a customer - that it sounded better (which I already the next day equalled by means of other tricks), that it was going to be modded in Switzerland by yet another bloke who could do it, and while this is now, I think almost 5 months ago, two weeks ago I was notified that the PSU would be on its way back to me in two weeks of time. yes

In parallel Anthony took a lot of effort in trying out things, tinkering on how to make "a best", that ending up in a design and even physical pinted circuit boards, which btw is also from 5 months ago by now.
Also in parallel, but maybe not known (I forgot) is that our Juan wanted to set up a linear supply (by an acquaintance of him) which back at the time I thought was dangerous because nobody really knew what to expect and certainly not me. But, I should guide and test it. So I said No to that project and/but let Anthony proceed with his (how and why to stop him anyway).

Oh, that Teradak is of course still not back and when it finally is back it has to sound better than it did or otherwise that project (actually not mine, but that customer's) has failed massively.

Now guys, I don't know what it is, but if you all really take such a long time with it then it is only the wait for me to have actually quite other ideas and, say, outsmart all of "it". Not you (I wouldn't dare) but "it" as in : how we can approach all a little differently, sort of start over and find yourself with such few puzzle pieces that things start to work automatically.

Before I forget it, let me say this (in all honesty !) :
Anthony, I don't know whether something went wrong, or that you just "take your time" like all of this world around LPSU's seem to do (in the end including myself), but this is your last chance. I mean, if you don't have something ready for production (but say listening trials) Tomorrow, then I have something for that Yesterday. Happy Happy

And what a F*CKING GOOD SOUND comes from that.


And what a mess it looks like. grazy

What you see in the front contains the LPSU but only two parts in the upper left and upper right corner plus the larger trafo. I can tell you that all fits in the PC you see in the back.
I can also tell you that the temperature of the "regulation" is 23.8C / 74.8F with an ambient temperature of 22C / 71.6F. And it is even playing ! Cool
But didn't I apply such trickery before ?

So you see, it *really* will fit in that PC, because it won't even get warm.



It looks like I got very smart and could work this out on a Sunday morning. But this is not true. It is the evolution of time and how week by week one can see things coming, try a thing, take a next step, try another thing, think a little, and decide for a final step (and now think this took years, say like Anthony's project also is (or seems) not finished yet for reasons).

The fun of this is also, that it requires references again. Thus, like the "sound" of the Teradak could already be superceded a next day with something else, there will also be merit in how that Teradak is overkill and therefore sounds "worse". I mean, I arrived where I am now by "steps" and each step showed its own nature of sound. Some weren't even the best and this is merely because of all ending up so totally black(ground) that there's too much "rest" as we say over here. One may like that, but that too implies a stuffed ear feeling. So it is a balance of black background and some "bite".
Furthermore I can tell you that power supplies to computers are as important to the sound as a D/A converter is and how software is. Possibly the PSU to the PC is even more important (says he who couldn't believe much of this in the first place).

The fun (for me) is that it is not the PSU on its own. It is a whole super big pile of all working together, in that PC housing. If one bit of it hadn't worked out, the LPSU in its current form would not have existed. If another part would not have worked out, the first part could not have been applied.
If XTweaks (which is software) would not have been created by me, we wouldn't even have been able to start thinking about what is happening today. Oh, Minimizes OS was ahead of it all, wasn't it ? Or maybe even Windows 10 is playing its little but crucial role.
ALL. Realy really ALL is required to let this work.

And yesterday it did.



It was even exciting, because at first nothing wanted to work, at the first attempt yesterday. No lights anywhere.
Found out that the voltage was 0.3V under par so that should be the culprit, but after changing that still nothing. This was a surprise because with a slightly (but 100 times more rough) different setup, all worked up to a couple of hours before. So what's up then ?

Remeasuring learned that no Voltage came from anywhere. Ah, ohh, oops, newbie mistake; the fuses in that general box had blown, which is a tiny little bit logical when they are 0.5A.

After they were replaced booting worked as before, but stopped when the display really had to do some work. This is how the video card ended up on the frame of the chassis (see picture).
Now it worked (and still does, now 14 hours later).

So, not 100% finished yet, as something was dimensioned just a little bit too tight. This is a pity because making "that" larger will again change the sound (yep, that's how it appears to work). But maybe I can be smart in some other direction; I already dreamt about a few things.

Addendum :

I expect that questions may be asked which I maybe not like to answer (not in here and not by private email). I have decided - and tell it in advance - to just ignore those questions (that feels a lot more comfortable than saying that you don't like to explain).
This does not mean (at all) that questions are not allowed; of course they are. But I feel that I was able to create something which at this moment is unique and I tend to let it be like that for as long as it lasts.

Later we will see that much more springs from this, or at least can spring from this;
Suddenly there's a whole new "possibilities" world and all is of course for again better sound (yeah, I know, all stumbles over each other over here without ending up to you, but hey ... I always want the best sound of the world for a while Wink).

Peter

Well, it seems that finally the long dream of getting a clean power for our Audio Pc approaches the end. Congratulations to the ones that have participated in it and also a special greeting for Anthony because his perseverance has also served to keep alive the idea that it could be done. Now we wait eagerly for the design, final adjustment and price.

Regards,
Juan

Peter, that is great!

I have dropped the ball since the boards where built due to music room renovations and painting the house,  plus I have until very recently not been able to leave high voltage stuff unattended due to small kids, but all that stuff is behind me now.

I have managed to start and stop the pc with my board but that was all that happened before I put it away and did the house stuff.  Would be keen to share notes though...

Before I forget it, let me say this (in all honesty !) :
Anthony, I don't know whether something went wrong, or that you just "take your time" like all of this world around LPSU's seem to do (in the end including myself), but this is your last chance. I mean, if you don't have something ready for production (but say listening trials) Tomorrow, then I have something for that Yesterday. Happy Happy

And what a F*CKING GOOD SOUND comes from that.


Hi Peter,

I have a case laser cut for my supply sitting here that I will put together next weekend then I will install the power supplies and get it all working in a tidy fashion.  So by the end of next weekend I should have my first functioning ATX LPS operating and ready for listening and tweaking.  That is if you want to do something that way...it does not really worry me and you seem reluctant to share your ideas whilst I have a LOT of ideas that I am willing to share in the course of things.  I can keep a secret, you already know that.

I even have the parts here to build up another completely different supply of most enviable on paper performance plus I am working with a local Australian electrical engineer for something else that is a bit out of the ordinary...and probably something quite special based on the results other computer power supply tweakers are managing in my part of the world.  It is up to you Peter.  I will keep doing my stuff over here regardless of what you do there, but it will have less priority for me if we are not working in parallel.  After all, I also have my 6 channel single ended triode amplifiers to build soon of which I have the first channel on the prototype bench right now (440vdc...yay!) but if you are keen to move forward on this ATX LPS stuff, I am willing to put some priority to that from now on.

Let me know.

Cheers,

Anthony

As you know, I've been using a Teradak for coming onto a year now. I can't remember if it made a big difference in SQ because it was a long time ago, and also there were so many other changes to the system at the same time. I think it did. But right now, I wouldn't necessarily recommend it. Why? Well...

... how we can approach all a little differently, sort of start over and find yourself with such few puzzle pieces that things start to work automatically.

I can think of 2 ways:

1) Use an Intona to galvanically isolate the audio PC from the DAC. Run the audio PC from a different circuit to the DAC. Then don't worry about the PC's PSU - just use a good SMPS.

2) Give up on using an audio PC altogether. Use something like the new Sonore MicroRendu. I've just ordered one... but will need to use it with a Linux-compatible DAC for now  unhappy

Happy to have my ideas shot down.

Hi Mani,

Are you sure that you would need a DAC compatible with Linux to work ? Isn't a dac OS agnostic ? For formats like PCM and/or DSD ok, but not an OS ? scratching

Yes, we will see more of specialized PC designs.

Happy to have my ideas shot down.

Mani, that is not all that difficult. None of such devices take into account what all can be done with a Windows PC (and Mac to a far lesser extent). So you are turning things upside down and only hope it works.
Nobody is working on such things to improve, say, monthly (make that yearly and it's still fine).

Let me tell you that once in a while you come up with these things because you (don't !) see that PC's can make things BETTER while you only think that PC's thus make things worse. This could be correct - but worse in comparison to what ? I mean, shouldn't you have gone back to the CD Player long gone by now ?

Are you okay ?

Oh ? The last time I suggested about exactly what was said in the previous quote and you told in reply that the Teradak for sure implied a big step forward. Actually that was in response to my suggestion it did not because you never talked about it. You then said exactly the same (similar) "yeah, but more things changed at the same time".

I recall that this forum should be about what we know for quite sure, and not what we like to say because of the moon phase.

Well, that was my way of shooting down ideas. Not explicitly, but please mind that you are doing this quite explicitly to the purpose of this thread. And *that* is what nobody likes, I'm sure.
