Mihalov,Thanks for the info. That sounds like it will be a great-sounding power supply. What regulators do you plan to use?
One thing I have been meaning to ask of someone who has the new motherboard... these new Gigabyte boards have the dual-bios setup like the GA-G31M-UD2H board I've tried. One thing that it did that made the startup a little more complicated was that it started up, then stopped, then started again after about 10 seconds (you could see it do this by the flashing on and off of the LED's on the board and on the PicoPSU).
Does the new H55M board do this too?
TIA!

Everything matters!

I am going to use my favourite regulator LT10xx-adjustable version (LT1084CP) for +5V and LM1085IT-3.3 for +3.3V.
My new system board starts also as well as previous, i.e. pressing the button on the front panel, the pause about 4-5 seconds, LED lights up over the button (an accessing to a hard disk), approximately in 3-4 seconds the screen with POST turn on.
Just to be clear...
Your "revised" plan has:
P4 module:
(+12V) regulator LT1083CP
P24 module:
(+3.3V) - regulator LT1085IT-3.3
(+5V) - regulator LT1084CP
(+12V) - regulator LM1085IT-12
-12V not necessary
Toroidal power transformer 60 VA with ONLY two secondary windings at 6V for +3.3V and +5V.
(Originally you had toroidal power transformer 100 VA with four secondary windings at 5-6V for +3.3V, at 6-8V for +5V, at 12-15V for 12V and 12-15V for -12V.)
Peripherical module:
(+5V at 3A) - regulator LM1084IT-5.0
(+12V at 2A) - regulator LT1083CP
Could you please confirm it.
Eventually, as I am not so technical, let me know exactly where the differences are between the two.
Thanks

(I used now the alternative decision of PSU is the so-called hybrid supply, which basis PicoPSU 120, providing all necessary voltages for socket P24 (P20) from entrance voltage +12 V).
This is the photo of my old platform (but the psu remained the same so far).

Thanks for your detailed reply.
Sorry I got confused between your system and your friend's uncompromising ATX linear supply.
This is the one I am interested in.
Does the PDF file of the full linear PS at cMP's site still stand or do you have any revision for it?
I do not know yet. It is possible to make the new revision without the voltage -12 V. Nevertheless it is desirable to have practical acknowledgement of working capacity of such version. Though I do not doubt it.
