In Figure 16, you can see the power supply label containing all the power specs.
This power supply is sold as having two +12 V rails. We could clearly see one “shunt” (current sensor) for each +12 V “rail,” and the monitoring integrated circuit has two +12 V over current protection channels. Click here to understand more about this subject.
The two +12 V rails are distributed like this:
- +12V1 (solid yellow wire): All cables but the ATX12V/EPS12V
- +12V2 (yellow/black wires): The ATX12V/EPS12V cable
This distribution is perfect, as it puts the CPU (ATX12V/EPS12V) and the video card in separate rails.
How much power can this unit really deliver? Let’s find out.
