Figure 17: Power supply label.

This power supply has two virtual rails (which is unusual for a power supply from this power range), distributed like this:

• +12V1 (solid yellow wire): Main motherboard cable, SATA power cables, peripheral power cables, one of the six-pin video card power connectors and one of the six/eight-pin video card power connectors.
• +12V2 (yellow with black stripe wire): ATX12V, EPS12V, one of the six-pin video card power connectors and one of the six/eight-pin video card power connectors.

There is not much you can do with only two virtual rails and lots of cables. One suggestion we have for Seasonic is to label outside the power supply the rails each cable is connected to, this would certainly help advanced users.

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