Power Distribution

In Figure 15, you can see the power supply label containing all the power specs.

Figure 15: Power supply label.

This power supply has four virtual rails (this unit has really four OCP circuits, as mentioned in the previous page), distributed like this:

• +12V1 (yellow wire with white stripe): Video card power cable with six-pin connector.
• +12V2 (yellow wire with blue stripe): ATX12V/EPS12V connectors.
• +12V3 (solid yellow wire): Main motherboard cable, peripheral and SATA power connectors.
• +12V4 (yellow wire with black stripe): Video card power cable with six/eight-pin connector.

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 650 W.
