Power Distribution
Contents
In Figure 19, you can see the power supply label containing all the power specs.
Figure 19: Power supply label
This power supply is advertised as having three +12 V rails, which is correct, since the monitoring integrated circuit has three +12 V over current (OCP) channels, and we clearly saw three current sensors (“shunts”) on the solder side of the printed circuit board. See Figure 20. Click here to understand more about this subject.
Figure 20: Shunts
The three +12 V rails are distributed like this:
- +12V1: ATX12V/EPS12V connector and main motherboard cable
- +12V2: Half of the red modular cabling connectors and two of the black modular cabling connectors (the ones closer to the red connectors)
- +12V3: The other half of the red modular cabling connectors and the other three black modular cabling connectors
This distribution is perfect.
