| Power Distribution |
 In Figure 14, you can see the power supply label containing all the power specs.  click to enlarge Figure 14: Power supply label.
According to the label, this power supply has four virtual rails. The difference between a single-rail power supply and a multi-rail one is the presence of individual OCP (over current protection) circuits on each +12V rail. On the manufacturer’s website there is no mention to OCP, however in our tests we could see that this protection was really there and active (at a value that we think was too high, however: 30 A; it should be set around 20 A in our opinion). The rails are distributed like this: - +12V1 (yellow with black wire): Half of the EPS12V connector, ATX12V connector).
- +12V2 (solid yellow wire): Video card auxiliary power connectors, half of the EPS12V connector.
- +12V3 (yellow with blue stripe wire): Main motherboard connector.
- +12V4 (yellow with orange stripe wire): Peripheral and SATA power connectors.
Now let’s see if this power supply can really deliver 750 W of power.
