This power supply has two rails, distributed like this:

• +12V1 (solid yellow wire): Main motherboard, ATX12V, EPS12V, SATA and peripheral power connectors.
• +12V2 (solid yellow and yellow with black stripe wires): The two video card auxiliary power cables.

This distribution is perfect, as it separates the CPU (ATX12V/EPS12V) and the video cards are located on different rails.

Now let’s see if this power supply can really deliver 800 W.
