Cougar CMX 700 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 is sold as having two +12 V rails, which is correct, since this unit has two +12 V over current protection circuits (see previous page). Click here to understand more about this subject.

The two +12 V rails are distributed as follows:

• +12V1: Main motherboard cable, the two video card cables that are permanently attached to the power supply, and the SATA and peripheral connectors
• +12V2: The ATX12V/EPS12V cable and the two video card cables available on the modular cabling system

The power supply has a sticker on the modular cabling system saying that one of the video card cables is connected to the +12V1 rail, and the other one is connected to the +12V2 rail. However, this information is not correct, as internally, both connectors are linked to the +12V2 rail using a yellow/green wire.

How much power can this unit really deliver? Let’s find out.
