Enermax PRO87+ 500 W Power Supply Review

Power Distribution

In Figure 18, you can see the power supply label containing all the power specs.

Figure 18: Power supply label

According to the label the power supply has three +12 V rails, and we can confirm that this unit really has three +12 V rails, as explained in the previous page. These rails are divided like this:

• +12V1 (solid yellow wires): ATX12V/EPS12V connectors and motherboard main cable
• +12V2 (yellow/black wires): SATA connectors, peripheral connectors (the ones available on the same cable as the SATA connectors), and one of the video card power connectors
• +12V3 (yellow/blue wires): Peripheral connectors and one of the video card power connectors

This distribution is perfect, as it separates the CPU and each video card power connector on individual rails.

Let’s now see if this power supply can really deliver 500 W.
