Enermax NAXN 82+ 750 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), and we could clearly see one “shunt” (current sensor) for each +12 V “rail.” See Figure 17. Click here to understand more about this subject.

Figure 17: Shunts

The two +12 V rails are distributed like this:

• +12V1 (solid yellow wire): Main motherboard cable, the ATX12V connectors, the EPS12V connector, and one of the video card power connectors from the modular cabling system
• +12V2 (yellow/green and yellow/blue wires): The two video card power connectors that are permanently attached to the power supply, one of the video card power connectors from the modular cabling system, and the SATA and peripheral power connectors

This distribution is adequate.

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