Figure 15: Power supply label.

This power supply has four virtual rails (the 500 W model has only two), distributed like this:

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

This configuration is listed on the power supply label, which certainly helps advanced users (not shown in Figure 15).

This distribution is perfect since it separated the CPU (ATX12V/EPS12V connectors) from the video card(s).

Now let’s see if this power supply can really deliver 600 W.
