Title says it all, Can you please show the link to it like on OKorder or something, thanks.
That PCI controller card does not need a power cable. It draws the power it needs from the PCI slot into which it is inserted.
I agree completely with the reply above However SOME eSATA cards that have external power jacks to power the external drive will have either a four pin Molex plug (same as an IDE/PATA drive) or a Floppy power plug. And back in the day when Firewire was more common any good firewire card had a power socket on it, again, either a Molex plug or a floppy power plug. AD
