All is fine - I needed a VCORE for my MB, and the 12V adapter I used worked perfectly.

The situation was, 20 pin PS, 20 pin ATX and 4 pin VCORE on MB. I needed to get 12V to the VCORE socket, and the $2 adapter I found at Microcenter fixed me right up - the machine booted right up once I added the adapter.

I put together a second system, and the MB wouldn't boot up, the lights on the keyboard kept cycling on and off. Turned out, after much head scratching, that the problem was I had reversed the keyboard and mouse connections :^( Switched them around, and booted up fine (sort of, but that's another story)...
