Hi Peter, am currently saving my nickles and dimes for a Mach II XXHighEnd PC. In the meantime, any way your pc linear power supply could be fitted with my current mb- the one from the old XXHighend PC? If so what might you charge for that?  Happy

Hey there Brian,

Well, things are a leeeeettle bit different from what you might expect. prankster

Fairly soon after the Stealth was created and hit the roads, I also made a linear PSU especially for the old XXHighEnd PC. But I never even announced it. I also never tested it, but it will work ... (it is based on the Stealth's).

This one is far more complicated because it anticipates whatever unknown jobs and as you may be able to envision from below photo, it allows for a million configurations for 3 different voltages at the same time (like 3.3, 5 and 12) but with the storage capacitors configured as you wish. Well, "you", indeed because I am not going to try it.

These configurations are about how capacitors make the sound in such a situation - same as with the Stealth. But the LPSU and its configuration for the Stealth was determined by me, which is a project in itself where it is about capacitor arrangements. Anyway, the Stealth is just as is, while this one is configurable until you drop dead.
To give the idea : Stealth has only 13,600uF of capacitance (this is deliberately so low) while this one can hold 68,000uF for 12V alone which is how this part of the PSU will operate for the XXHighEnd PC. And 15A.

For ourselves we have a crazy document about what jumpers to put where for the configuration which is about all the numbers you see. Below you also see three drawings which are only for ourselves so we could make that document with jumper settings and to prove that no shortcuts occur / paths are used in combination which is not allowed. These are 3 drawings out of 12 we have for the various base combinations of how the voltages van be set up.

You know, you won't be inerested in this at all, but it is a kind of nice to show what happens all behind the scenes and that more projects never see daylight than those which do. This one actually did, but I never utilized it.

To come up with the price out of the blue is a bit difficult at the moment because it is mainly about the testing which never happened and the by now necessary explicit build of such an older PC. But I still have the parts for one, so this is doable. Of course the main thing is about whether it can hold (the power etc.) and whether the heat can be dissipated. But of all was calculated correctly, it can.
Think in the range of 400 - 450 euros. Maybe less.

Lastly, this board was very precisely created for exactly that cabinet of the old XXHighEnd PC. This includes that cut off corner, as it needs to be upright and then also the transformer can be neatly in there.

Call me crazy, OK ?
Peter

Wow Peter, cannot thank you enough for even considering this. Do you ever rest? Your work is amazing.

Anyway, I would be looking for the very simplest linear supply: one output for the mb of the old XXHighEnd PC as well as  proper outputs for the processor on the mb. I simply lack the know how to work with too many options/or choices and I would not be in a proper position to do testing.

No big deal if you are not interested. I agree it's important that folks get to see a bit of the work no one knows about!
