Figure 20 shows the power supply label containing all the power specs.

As you can see, the manufacturer lists this unit as having five +12 V rails. Analyzing the circuit, we could clearly see five “shunts” (current sensors) matching the number of rails advertised by the manufacturer. See Figure 21. We also tested the over current protection (OCP) of each rail, and they worked as expected, proving that this unit really has five +12 V rails. Click here for a more detailed explanation.
Figure 21: Shunts
The available +12 V rails are distributed as follows:
- +12V1: Main motherboard cable, SATA and peripheral power connectors
- +12V2: The ATX12V/EPS12V cable
- +12V3: The two red connectors of the modular cabling system
- +12V4: One of the blue connectors of the modular cabling system
- +12V5: The other blue connector of the modular cabling system
Let’s now see if this power supply can really deliver 900 W.
