This power supply has four +12 V rails distributed like this:

• +12V1 (yellow with black stripe wire): Main motherboard cable, SATA and peripheral power cables (including the ones from the modular cabling system).
• +12V2 (solid yellow wire): ATX12V and EPS12V cables.
• +12V3 (yellow with blue stripe wire): One of the video card auxiliary power cables that come from inside the power supply and the first video card power connector from the modular cabling system.
• +12V4 (yellow with green stripe wire): The other video card auxiliary power cable that comes from inside the power supply and the second video card power connector from the modular cabling system.

This is a nice distribution.

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