What does "PCI-E2/CPU2" mean on the OCZ StealthXStream 600W psu label?

Howdy,

According to the label (URL below), the OCZ StealthXStream 600W power supply has "PCI-E2/CPU2" on the 12V2 virtual rail, and PCI-E1 on the 12V4 virtual rail. What does "PCI-E2/CPU2" mean? Would I be correct in assuming that one of the two PCI-E connectors (i.e. PCI-E2) is fed by 12V2, and the other is fed by 12V4?

But looking at the mechanical drawings at OCZ's website (http://www.ocztechnology.com/drivers/600SXS_MD.pdf), I saw that the two PCI-E connectors are labeled as 12V4. So what in the world does the label mean when it says that "PCI-E2/CPU2" is on the 12V2 rail? I want to apologize in advance for my lack of power supply literacy, and I would greatly appreciate any information. Thanks!

Yep, the first PCI-E (graphics power) connector is on the +12V4 rail, and the second PCI-E connector is on the +12V2 rail. The +12V2 rail is also used for the 4pin/8pin CPU power connector.
