Cooler Master Elite Power 400 W Power Supply Review

Power Distribution

In Figure 12, you can see the power supply label containing all the power specs.

Figure 12: Power supply label.

As you can see, according to the label this unit has two +12 V rails. Inside the unit we could see two shunts (current sensors) attached to each +12 V rail. The two rails are divided like this:

• +12V1 (solid yellow wire): ATX12V/EPS12V cable, peripheral connectors and SATA power connectors.
• +12V2 (yellow with black stripe wire): Main motherboard cable and video card auxiliary power connector.

This distribution is good since it separates the CPU (ATX12V/EPS12V) from the video card.

Now let’s see if this power supply can really deliver 400 W.
