thanx, good link, has what I need. the P4 connector is still a mystery, but I'm just trying to dump more current onto the 3.3v section to see if I can power up a Radeon 9700 (appple OEM) in a Quicksilver.

The small package on a B&W which contains the power and reset/nmi switches appears to output ~28v from a standard molex input -- I wonder if that could be used to drive the 28v on a digitalaudio and up MB? I'd wonder if it could generate enough current for the ADC, but other than that...
