In Win GreenMe 650 W Power Supply Review

Power Distribution

In Figure 20, you can see the power supply label containing all the power specs.

Figure 20: Power supply label

This power supply is advertised as having four +12 V rails, which is correct, since the monitoring integrated circuit has four +12 V over current protection (OCP) channels, and we clearly saw four current sensors (“shunts”) on the solder side of the printed circuit board. See Figure 21. Click here to understand more about this subject.

Figure 21: Shunts

The four +12 V rails are distributed as follows:

• +12V1 (solid yellow wires): The main motherboard cable and the peripheral and SATA connectors
• +12V2 (yellow/black wires): The ATX12V/EPS12V connector
• +12V3 (yellow/blue wires): One of the video card power connectors
• +12V4 (yellow/green wires): The other video card power connector

This distribution is perfect.
