Two PCI-E(6+2 Pin) Power Cables.

This is a very detailed guide, that is very awesome. Seriously I'm impressed.

However, under your own recommended power supply, there are only TWO PCIE cables. So you apparently you disagree with EVERYONE on the overclocking thread the you need 4 pcie cables to power the S3.

This is the issue we keep harping on, not the power draw, not the 12V rails, its the wires. Everyone says you need 4, then everyone suggests you buy a power supply with 2. I fully expect that I'm missing something here, but so far, people just keep acting like they don't understand why I'm not getting this. But when you tell me I need 4, then you give me 2, I'm going to ask questions.

These days I always recommend using 4 cables for S3 even if not overclocking.
But if we go for a PSUs considering the PCI power connector cable numbers, there is no meaning in it.
In the above suggested power supply as already said there are only 2 PCI-E(6+2) power cables.
So you can plug them into your S3. Additionally for the other two cables you can easily buy,
two Molex->PCI connector cable from ebay or other sites for less than a dollar.

Going with the molex to pcie idea, I was under the impression that would pull from the +5V@20A, NOT the +12V@38A. I was also under the impression we had to pull from the +12V rail? Putting these together would imply to me it's a bad idea to use the molex to pcie idea?

This does make a lot of sense though, and does deal with the incongruencey I was dealing with. I was under the impression that you can't do the molex idea, but it at least explains the needing 4 wires, and being handed 2 wires, so thank you.

Other people have been saying two pcie connectors on one pcie cable is the same as two pcie cables, which makes no sense to me. If you are going to plug in two pcie connectors per blade from one pcie cable, you might as well plug in one pcie connector per blade.

The two black lines in the 4 lines is COM, the yellow is +12VDC(pin 1) and the red is +5VDC.
There is no problem in using them as your second PCI power cable to S3 blades.
The double PCI power connectors on a single PCI cable will not serve the purpose.
For this CX500 power supply connect the PCI power cable(6+2) to each blade.
And if you want to connect all the four PCI power ports, use 2 molex to pci to connect one each blade as secondary.
