4 of 4............. I just realized- this is an old AT supply, however, you easily get the idea with the ATX board.

Default Dc-dc Atx P4 Psu

Here is a thumbnail of a 250W 12V DC-DC ATX box I found somewhere in the internet- I don't remember where. I believe it has DC-DC ground isolation, too.

I picked up a 300W DC-DC ATX PSU with 24V input last year on eBay for US$45.00. Of course, the very first thing I did was crack it open to see what is inside. The output section is pretty much the same as a standard line-powered ATX, but the 5VSB is on a separate board, with galvanic isolation. I believe it is either single-ended forward, or centertap push-pull. Need a further look......
