Power Distribution
Hardware Secrets Silver Award

On Figure 14 you can see this power supply label containing all its power specs.

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.

Let’s now see if this power supply can really deliver 750 W of power.
