Hi all:
Before i ask some guestions about power supply in MB for PCI card.
I still have a question about that I usually see PCI card used 5v for
power supply source.
But if there are all 3.3V components in my PCI card , so i don't want
add a power regulator to transfer 5v to 3.3v .
So can i only use 3.3v pin in PCI card?
(i saw 3.3v pin is workable in PCI spec 2.2 )

PS:I affraid of it's wrong that i don't use 5v pin and use power
regulator to suppy 3.3v component power.......
if anyone cah tell me,wrong or true?
thanks

Regards.
