There are a bunch of white connectors on my unit.
In addition to the standard 4-pin Molex connectors (8), there is a white mini-drive connector (for floppy drive type devices), as well as all three of the motherboard connectors (the 4-pin, 6-pin and 24-pin).
The SATA and the PCI-E connectors are all black.
Hope that I counted right, after all, I only have so many fingers to work with.
