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