Power Distribution
Contents
In Figure 18, you can see the power supply label containing all the power specs.

This power supply has four +12 V virtual rails, as we could confirm by the presence of four “shunts” inside the power supply (see Figure 19).

The four rails are distributed like this:
- +12V1 (solid yellow wires): Main motherboard cable, SATA, and peripheral power connectors
- +12V2 (yellow/black wires): ATX12V/EPS12V connector
- +12V3 (yellow/blue wires): One of the video card power cables
- +12V4 (yellow/green wires): The other video card power cable
This distribution is perfect, as it separates the video card cables and the CPU in different rails.
Let’s now see if this power supply can really deliver 600 W.
