Power Distribution

In Figure 23, you can see the power supply label containing all the power specs.
Figure 23: Power supply label
As you can see, the manufacturer labels this unit as having four +12 V rails, which is correct, since the monitoring circuit has four over current protection (OCP) channels, and we could clearly see four shunts (current sensors) on the solder side of the printed circuit board.

The four rails are distributed as follows:
- +12V1 (solid yellow wire): Main motherboard cable, SATA and peripheral power connectors
- +12V2 (yellow/black wire): The ATX12V/EPS12V cable
- +12V3 (yellow/blue wire): The video card power cable that is permanently connected to the power supply
- +12V4 (yellow/white wire): The video card power cable on the modular cabling system
This distribution is perfect, as it separates the CPU and the video card power cables on individual rails.
How much power can this unit really deliver? Let’s check it out.
