Power Distribution

In Figure 23, you can see the power supply label containing all the power specs.

In Win Commander III 700wFigure 23: Power supply label

This power supply is advertised as having four +12 V rails, which is correct, since the monitoring integrated circuit has four +12 V over current protection (OCP) channels, and we clearly saw four “shunts” (current sensors). See Figure 24. Click here to understand more about this subject.

In Win Commander III 700wFigure 24: Shunts

The four +12 V rails are distributed as follows:

  • +12V1 (solid yellow wires): The main motherboard cable and the peripheral and SATA connectors
  • +12V2 (yellow/black wires): The ATX12V/EPS12V connector
  • +12V3 (yellow/blue wires): The video card cable that is permanently attached to the power supply
  • +12V4: (yellow/green wires): The video card cable that is available on the modular cabling system

This distribution is perfect.

Let’s find out how much power this unit can deliver.
