In Figure 15, you can see the power supply label containing all the power specs.
According to the label, this unit has two +12 V rails. Inside the unit, we could clearly see two “shunts” (current sensors), one for each +12 V rail. The monitoring circuit really has two +12 V over current protection channels. Click here to understand more about this subject.
The two +12 V rails are distributed as follows:
- +12V1: The cables attached to the modular cabling system
- +12V2: The cables permanently attached to the power supply
Usually, on power supplies with two +12 V rails, one rail is dedicated to the ATX12V/EPS12V connector. However, on this power supply, the manufacturer added the main power supply connector to the same rail, which is fine.
How much power can this unit really deliver? Let’s find out.
