On Figure 17 you can see iGreen Power 430 W label stating all its power specs.

What immediately caught our eye were the two separated +12 V lines listed on the label (see Figure 17). As we showed on the previous page, only one +12 V circuit is used inside this power supply, so it has only a single +12 V rail. Cooler Master separated the +12 V wires into two groups, called +12V1 and +12V2, but they are connected together on the power supply printed circuit board.

You can see that on Figures 18 and 19. On Figure 18 you can see the two separated wire groups, but they are connected together by the two jumpers (wires) located on the left side. On Figure 19 you can see how these two groups are simply connected together to the same single +12 V rail.

As we discussed on the previous page, the rectifiers used on this power supply have current specs far higher than this power supply can actually deliver. So other components are limiting the amount of current (and thus power) this power supply can deliver, like the capacitors and the coils used on the secondary, the transformer, etc.
