Hello, Can anyone help me? I m designing a fanless 12V DC-DC ATX power supply for mini-ITX form factor PC. I cant find the current requirements for each supply voltage. The motherboard i gonna try on is intel D510. This is the first project i do on my own. Can provide me some advice and information? THANKS alot!!!
If you are struggling with the current requirement step, I feel you might not have enough experience in electronics and electronics design to completly design a fanless SMPS. Could you pick a different project?
The links will provide the specifications and tolerances you need to meet the design guide specifications. You really are getting into what is a major project.

This link shows a schematic for an early ATX form factor 200 watt PSU. I suggest you look it over very carefully and see how the outputs are derived. That should help a little.

The schematic I posted is the basic circuit for just about all power supplies of that type. Designing and building a PSU like that is not a simple or easy task. That circuit is your basic SMPS for an ATX application. That is also only a 200 watt PSU and nowhere near as complex as the newer designs and much higher power units. Start with the mains power and work from there. That is about all I can tell you. All power supplies of this type look about like what you see, beyond that I don't know what to tell you. There is no easy way around it of a simpler version that I could suggest.
