Power Distribution

In Figure 15, you can see the power supply label containing all the power specs.
Figure 15: Power supply label.
As you can see, according to the label this unit has four +12 V rails. Inside the unit we could clearly see four current sensors (“shunts”) and the monitoring circuit really has four over current protection channels. Therefore this unit really has four +12 V rails (read our Everything You Need to Know About Power Supply Protections tutorial for more information).
The four available rails are distributed like this:
- +12V1 (yellow/black wire): ATX12V/EPS12V cable.
- +12V2 (solid yellow wire): Video card power cables from the modular cabling system.
- +12V3 (yellow/blue wire): Video card power cables that are permanently attached to the power supply and motherboard main cable.
- +12V4 (yellow/orange wire): SATA and peripheral power cables.
Now let’s see if this power supply can really deliver 750 W.
