On Figure 14 you can see this power supply label containing all its power specs.

As you can see this power supply has two virtual +12 V rails. As mentioned before we could clearly see on the printed circuit board that each rail was really connected to the over current protection (OCP) circuit, but this protection failed during our tests (more about this later) meaning that in practical terms this power supply is working as a single-rail unit.
These two rails are divided as following:
+12V1: Main motherboard cable, auxiliary power cable for video cards and all peripheral cables.
+12V2: EPS12V/ATX12V cable.
Let’s now see if this power supply can really deliver 600 W of power.
