This power supply has four rails, distributed like this:

• +12V1 (solid yellow wire): Main motherboard, SATA and peripheral power connectors.
• +12V2 (yellow wire with black stripe): ATX12V/EPS12V connectors.
• +12V3 (solid yellow wire): One of the video card power cables.
• +12V4 (solid yellow wire): The other video card power cable.

This distribution is perfect, as it separates the CPU (ATX12V/EPS12V), the video card and all the rest on different rails.

Now let’s see if this power supply can really deliver 750 W.
