yes and I have read that thread. Very interesting stuff but let me point out:

- I have not seen the psu finished, but let us assume it has been completed and rocks as it should.

- can anyone build it? The layout Uncle Jimbo ha devised is surprisingly simple yet effective. Multiple volts, independent rails, limited number of components and none of them are very expensive.

- How much would a toroidal transformer cost you if you decided to build that psu?

- What would happen if it broke? To whom would you turn to? A market product would be too expensive to buy so repairs would have to be made. How many hardware failures would occur and what would be the total cost for the end user?

- The type of modular design we have here is bulky (but not by much. low wattage psus are not that big) but has the benefit of being custom in terms of number of units. The mutiple relays are for the amps envolved. Also with some attention to ventilation the PSus can be disposed in different manners. I have found the most efficient in terms of space on the floor vs height but combinations are possibile.

- How efficient would my system be compared to the one Hipro is building? Let us say I load each one of my psus at 50% capability or slightly more. Isn't that the point on the performance-to-watt curve where psus can achieve max efficiency?

I have not even started building the system but honestly it starts to sound a "distributed vs central" debate similar to the ones which often emerge when reading about computational power requirements in modern super computers.

Anyway I am just weighing pros and cons before ordering components. What needs to be addressed is probably the switching mechanism for the tec voltages but that can wait.
