          why would anyone bother? only EXPERIENCED technicians will have the expertise to pull apart all that info and make something of it, let alone a power supply that will work, and every and i mean every PC has a atx power supply, that is different. Its just easier to go and biuld a sproggy or buy a opus or ITPS *shrug*
          I biult a sproggy, then bought a ITPS and used both, sold that car, and now im going to order one of those new 200watt ones when they come out (very similar to ITPS)

                      The first attachment appears to be only an ATX shutdown/startup controller. It appears to be functional as best as I can tell. I am somewhat familiar with the second attachment. It has no 3 volt tap, and will not power an ATX board. It also requires specialized chips and inductors and has no advantage over a "Sproggy type design. The third supply does have a three volt output stage, and will power an ATX board, but again requires a specialized transformer and Pulse Width modulator chip. It also appears to need a shutdown/start up controller, and from what I can tell, the one attached does not appear to be compatable. As was previously stated, unless you have the technical knowhow to design and build your own supply, you're better off building a Sproggy type supply from parts yourself, or ordering a partial or complete kit.

                      Hope that helps!

                          There is something coming that is similar to ITPS but is capable of 200 Watts? Link?
