Cooler Master Extreme 2 475 W Power Supply Review

Power Distribution

In Figure 15, you can see the power supply label containing all the power specs.

Figure 15: Power supply label

This power supply is advertised as having two +12 V rails, which is correct, since the monitoring integrated circuit has two +12 V over current protection (OCP) channels, and we clearly saw two current sensors (“shunts”) on the component side of the printed circuit board. See Figure 16. Click here to understand more about this subject.

Figure 16: Shunts

The two +12 V rails are distributed as follows:

• +12V1 (solid yellow wires): All cables but the ATX12V/EPS12V
• +12V2 (yellow/black wires): The ATX12V/EPS12V connector

This is the typical distribution used by power supplies with two rails, and it is perfect.

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