Gigabyte Odin Plus 700 W Power Supply Review

Power Distribution

In Figure 17, you can see the power supply label containing all the power specs.

Figure 17: Power supply label.

As you can see, according to the label this unit has four +12 V rails. Inside the unit we could clearly see four current sensors (“shunts,” see Figure 18) which are connected to an LM339 voltage comparator and then connected to the over current protection input of the WT7520 monitoring circuit. Therefore this unit really has over current protection (OCP) for each +12 V group of wires and thus four +12 V rails (read our Everything You Need to Know About Power Supply Protections tutorial for more information).

Figure 18: Current sensors (“shunts”).

The four available rails are distributed like this:

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

This distribution couldn’t be better, as it separates each video card and the CPU (ATX12V/EPS12V connector) on separated rails.

Now let’s see if this power supply can really deliver 700 W.
