Enermax REVOLUTION85+ 920 W Power Supply Review
Power Distribution
Contents
In Figure 21, you can see the power supply label containing all the power specs.
This power supply has four +12 V rails, and we can confirm that the over current protection (OCP) circuit supports four +12 V channels and the unit has four +12 V “shunts” (current sensors), as shown in Figure 22.
The available rails are distributed like this:
- +12V1 (marked black inside the unit): Main motherboard cable, and ATX12V and EPS12V connectors
- +12V2 (marked white inside the unit): Three of the black connectors (the ones that are closest to the red connectors) and one of the red connectors (the one that is closest to the black connectors) of the modular cabling system
- +12V3 (marked yellow inside the unit): Two of the black connectors (the two farthest from the red connectors) and one of the red connectors (the one in the middle) of the modular cabling system
- +12V4 (marked blue inside the unit): Video card power connectors that are permanently attached to the power supply and the last red connector (i.e., the one that is farther away from the black connectors) of the modular cabling system
This distribution is perfect.
Now let’s see if this power supply can really deliver 920 W.
