Amacrox Free Earth 88PLUS 600 W Power Supply Review

Power Distribution

In Figure 16, you can see the power supply label containing all the power specs.

Figure 16: Power supply label

This power supply has four +12 V rails, and we can confirm that the over current protection (OCP) circuit supports four +12 V channels.

The available rails are distributed like this:

• +12V1 (yellow/black wire): Connectors for video cards labeled “PCI-E3” and “PCI-E4”
• +12V2 (yellow/blue wire): ATX12V/EPS12V connector (“CPU1”)
• +12V3 (yellow/white wire): ATX12V connector (“CPU2”) and connectors for video cards labeled “PCI-E1” and “PCI-E2”
• +12V4 (solid yellow wire): Main motherboard cable, SATA power connectors, and peripheral power connectors

This distribution is perfect, as separates the CPU and the video cards in individual rails.

The names of the rails as listed on the power supply label are different. We used the names on the power supply printed circuit board. But the presence of a list on the unit label and the labeling of the video card power connectors and ATX12V connectors is definitely handy for the user concerned about rail distribution.

Now let’s see if this power supply can really deliver 600 W.
