Figure 15: Power supply label.

According to the information present on the product box this power supply is labeled at 40º C.

As you can see this power supply has three +12 V virtual rails, distributed like this:

• +12V1 (solid yellow wires): Main motherboard cable and ATX12V connectors.
• +12V2 (yellow with blue stripe wires): Two of the power cables for video cards, standard peripheral plugs.
• +12V3 (yellow with black stripe wires): The third power cable for video cards, SATA power plugs.

We liked the way power was distributed on this power supply, especially because the CPU (ATX12V/EPS12V connectors) does not share the same rail as any of the video card auxiliary power cables. When this happens the power supply may shut down even if your system is running inside specs, as the over current protection (OCP) may enter in action if you are pulling more than that particular rail can deliver.

Let’s now see if this power supply can really deliver 525 W of power.
