Enermax Triathlor FC 650 W Power Supply Review

Power Distribution

In Figure 22, you can see the power supply label containing all the power specs.

Figure 22: 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 “shunts” (current sensors). See Figure 23. Click here to understand more about this subject. 

Figure 24: Shunts

The two +12 V rails are distributed as follows:

• +12V1: The main motherboard cable, half of the two red connectors for video card cables, and two of the connectors on the modular cabling system for peripheral and SATA connectors (the ones closer to the red connectors)
• +12V2: The ATX12V/EPS12V connector, the other half of the two red connectors for video card cables, and three of the connectors on the modular cabling system for peripheral and SATA connectors (the ones farther from the red connectors)

This distribution is interesting, as when using one video card with two power connectors, each connector will be connected to a separate +12 V rail.

Let’s find out how much power this unit can deliver.
