Power Distribution

On Figure 15 you can see this power supply label containing all its power specs.

Figure 15: Power supply label.

As you can see this power supply has four virtual +12 V rails. We could clearly see on the printed circuit board that each rail was really connected to the over current protection (OCP) circuit. The only wires that use a different color are the wires connected to the +12V4 rail.

These rails are distributed like this:

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

The power distribution on this power supply is simply perfect, as with four rails the manufacturer could use individual rails for each main device (video cards and processor).

Let’s now see if this power supply can really deliver 700 W of power.
