Figure 13: Power supply label.

As you can see this power supply has two +12 V rails, which are distributed like this:

• +12V1 (yellow with black stripe wire): Main motherboard cable, peripheral power connectors, SATA power connectors and video card power connector.
• +12V2 (solid yellow wire): ATX12V/EPS12V connector.

The rails are well-distributed, as the CPU (ATX12V/EPS12V) and video card are on different rails.

Now let’s see if this power supply can really deliver 500 W.
